3.2.2 Short-circuit Short time delay Protection Characteristics
Intelligent controller's short-circuit Short time delay protection methods comprises inverse time protection and
denite time restriction protection.
1. Inverse time protection: When the fault current exceeds the present setting current value but is smaller than
the maximum setting short-circuit current (10Ir), the controller will carry out protection (10Ir)2*Tsd=I2*t
according to the inverse time curve. When the fault current exceeds the maximum setting short-circuit
current (10Ir), the controller will carry out delay protection according to the present delay setting value.
2. Definite time protection: When the fault current exceeds the present setting short-circuit current, the
controller will carry out delay protection according to the present delay setting value.
3. When overload long-delay setting time Tr = 5s or 10s, the short-circuit protection enforced setting will be
denite time protection (unadjustable).
Technical parameters of short-circuit short time delay protection characteristics are listed in Table 2.
3.2.3 Short-circuit Instantaneous Protection Characteristics
The operation time of short-circuit instantaneous protection (including the original breaking time of the circuit
breaker) should be less than 100ms. Parameters of the controller's short-circuit instantaneous protection
characteristics are listed in Table 3.
Table 2. Technical parameters of short-circuit short time delay protection characteristics
Table 3. Technical Parameters of Short-circuit short time delay Protection Characteristics
Note: When delay setting value is set to “I2 T ON”, the controller will carry out protection according to the inverse time method,
and the denite time function will automatically become invalid. When delay setting value is set to “I2 T OFF”, the
controller will carry out protection according to the denite time setting, and the inverse time function will automatically
become invalid.

3.2.4 Unsymmetrical Earthing / Leakage Protection Characteristics
Intelligent controller's earthing protection methods comprise inverse time protection and definite time
protection.
1. Inverse time protection: When the fault current exceeds the present setting current but is smaller than 5Ig, the
controller will carry out protection (5Ig)2*Tg=I2*t based on the inverse time curve. When fault current exceeds
5Ig, the controller will carry out protection based on the current delay setting value (which is the denite time).
2. Denite time protection: When the fault current exceeds the present setting earthing current, the controller will
carry out delay protection according to the present delay setting value.
Technical parameters of earthing/leakage protection characteristics of the controllers are listed in Table 4.
Table 4. Technical Parameters of Earthing/Leakage Protection Characteristics
Single-phase earthing protection is a metallic protection when fault current exceeds 800 ampere. This is generally applied
to neutral-point direct earthing system. There are two kinds of protection modes for the controller. One is the vector sum
mode of internal transformer (earthing protecting). The controller carries out protection according to the three-phase
current and neutral polar current vector. The number of poles of circuit breakers can be divided into three types, 3PT, 4PT,
and 3P+N. This method in general is suitable for a balanced load. It is not suitable for an imbalanced load or a motor load.

Another is transformer mode of external leakage. The controller gets the output current signal from a current transformer
directly to protect. Generally, the secondary output of the transformer is 5A/1A (secondary current is 1A if primary current
of transformer is less than 400A, else is 5A). This mode has higher sensibility especially applied to protect earth fault
whose current is smaller beginning from tens of amperes. There are two methods of ground signal's sampling. One is
rectangular transformer sampling mode (shown as follow Mode1, Model 2). Another is ring transformer sampling mode
in which the transformer's diameter is 100MM (Mode 3 for reference).

3.2.6 Phase Failure Protection Characteristics
Phase failure protection provides protection for phase failure according to the present three-phase current
imbalance rate. The current imbalance rate equation is shown below.
δ=| I-Iav|/Iav
In the equation：Iav is the average of three-phase current.
The feature of phase failure protection is xed time protection. The delay setting value is tδ. If the setting is "OFF",
the phase failure protection function is o.
Technical parameters of phase failure protection characteristics of the controllers are listed in Table 6.
3.2.7 Other Functions
Test functions
The controller uses the instantaneous mode to simulate tripping for testing. After the test, tripping action will be
generated. This test is used for coordinating the controller with the circuit breaker for onsite-tripping tests, routine
check, or repairing and checking the coordination between the controller and the circuit breaker. Press the red
restore button on the panel of the controller before closing the circuit breaker for starting the operation. Do not
use it during normal operation.
Fault record functions
If there is any controller fault (either tripping or self-diagnosed faults), all relevant conditions and data of the fault
will be recorded. After restarting after a fault or power failure, fault memory function is still available and can keep
ten latest fault cases for later analysis. Concrete query methods are presented in 8.2.3.
The tripping type of faults include overload, short-circuit, sudden tripping, earthing/leakage (optional), and phase
failure.
Self-diagnosed faults include overheated, worn contact, and failure to trip.
Table 6. Technical Parameters of Phase Failure Protection Characteristics
The controller can program the output of two passive signal contacts for load monitoring. The output signal
contacts can be used for monitoring alerts, controlling the load of tripping sub-circuit and ensuring a normal
power supply for the main system. There are two types of load monitoring methods available (the user can choose
one of them).
1. Method 1: It can be used to control two sub-circuit loads. When the working current exceeds 1.2Ic1 or 1.2Ic2, controller will
delay the output of signal contacts according to inverse time characteristics. The characteristic curve of inverse
time and the characteristic curve of overload long-delay are the same, but the setting current value can be set
independently.
2. Method 2: It is generally used to control sub-circuit loads. When the working current exceeds 1.2Ic1, the controller will output
signal contact point break sub-circuit load according to inverse time characteristics. The characteristic curve of
inverse time and the characteristic curve of overload long-delay are the same, but the setting value has to be
Ic1 ≥ Ic2. If after tripping the sub-circuit load, the current will return to normal. When the current is lower than Ic2
for 60s continuously, the controller will output another signal contact to pick up the broken load and restore the
power supply of system.

Self-diagnosed functions
When the working environment of the controller exceeds 65oC or when 60% of the contact has been worn o,
or when the circuit breaker cannot be tripped, the light "TAL" on the controller panel will be on to alert the user.
Relevant parameters will be recorded for later inquiry.
Thermal memory functions
Repeated overload can heat up the conductor or other devices. The controller can simulate the heating conditions
as well as the overload long-delay, short-circuit delay, and other fault or delay actions to generate the thermal
eect (simulating characteristics of the double-metal piece). The overload long-delay thermal eect energy will
be completely released in 30 minutes after eliminating the fault. For short-circuit delay thermal eect energy, it
will be completely released in 15 minutes after eliminating the fault. During the period, the delay time will be
shortened if the reclosing circuit breaker has overload long-delay or short circuit short-delay. This is to provide
circuits and devices better protection.
If the controller is turned o rst and then turned on, all the accumulated thermal eect will be cleared.
The factory default of this function is "ON", which means that the thermal memory function is running.
System clock function
The system has a clock function for recording the time and date when faults happen. For adjusting the system
clock, the method is presented in 8.2.3.
Alert signal function (Only for XSIC-P controllers)
The controller has four sets of independent signal contact output. This function can be set using the control panel
or remote communication. For contact function, please refer to Table 7. For the factory default of the four contact
sets of the controller, please refer to Table 8.

INSTRUCTIONS
Simulating calculation of circuit breaker contact wearing rate
The controller will simulate and calculate the circuit breaker's main contact wearing rate according to information
such as the fault current at tripping. The contact value of the controller from the factory is 100%, indicating no
wearing of the contact point. The contact will be worn by a certain level due to every fault induced tripping. If the
value obtained from subtracting the corresponding amount of wearing from the current contact value is less than
40%, the system will send out a self-diagnosed fault alert signal (by the "TAL" light and the contact signal, if such
functions have been set) to notify the user to carry out maintenance.
After changing the main contact of the circuit breaker, the user can reset the initial wear rate to 100% through the
main-machine interface or remote communication.
Table 8. Factory Default Setup for the Four Contact Sets of the Controller
Note: 1. When the overload monitoring function is turned on, the functions of contact 3 and 4 are xed to "Load 1
Unloading Output" and "Load 2 and Unloading Output".
2. When the controller has communication functions, contact 1 and 2 are xed to "Remote control: tripping"
and "Remote control: closing".

5.3.2 Three-lock-two-key interlocking device
The three-lock-two-key interlocking devices are used on occasions where the breakers are
xed dispersedly. The locks are xed on the panels of the three breakers separately. When the
key had been inserted and rotated to horizontal position, the breaker can carry on make-break
operation. The closed breaker will be broken if rotate the key anticlockwise from horizontal to
vertical position. At the same time, making operation is forbidden and the key is allowed to
take out. It ensures that there are not more than two breakers can be closed at the same time
because there are only two keys for three locks.
5.3.2.1 Key lock
The structure of the breaking lock is the same as the three-lock-two-key. However, there is only
one key for one lock. If the o button of the breaker is locked, the on button will be disabled.
5.3.4 Button lock
The cover on the ON/OFF button with padlock position attached on ACB panel. This device
doesn't come with padlock.
5.3.5 Racking lock
It is used in drawout type breaker and it is possible to lock the disconnection, connection, test
positions.
5.3.6 Position lock
The red color button will pop up and lock the breaker main body in the position of
disconnected, test or connected.
Press the red button for continuing draw in/out the main body.
The padlock can be attached on this device.
5.3.3 Door interlock
This prevents the compartment door to be opened when the circuit breaker closed. The cdoor
interlock xed in the foot right corner of the drawer seat.
a. The door interlock is allowed to close or open at will if the breaker is at the disconnection
position (relative to cradle).
b Breaker can be pushed in or pulled out to any position between connection and
disconnection if the compartment
door opens.
c. Breaker will be locked once the door is closed after the breaker leaving the disconnection
position.
