I. Overview
The HYW3 Series Intelligent Universal Circuit Breaker (hereinafter referred to as “the circuit
breaker”) is suitable for distribution networks with AC 50/60 Hz, rated working voltage up to 690 V
and rated current below 6,300 A. The circuit breaker is mainly used for distribution, feeding and
power generation protection to protect circuits and power supplies from HHH load, undervoltage,
overvoltage, imbalance of current and voltage, short circuit and grounding. The circuit breaker can
also be directly used for overload, undervoltage and short-circuit protection of motors and
generators. The core component of the circuit breaker adopts the intelligent controller, which has
accurate selective protection, so as to avoid unnecessary power failure and improve the reliability,
continuity and safety of power supply. The circuit breaker is also equipped with an open
communication interface to realize telemetering, telesignaling, telecontrol and teleregulation, thus
meeting the requirements of the control center and automation system.
The circuit breaker complies with GB/T 14048.2 and IEC 60947-2.

3.1.2 Function introduction
● Main protection functions (The functions of the controller have been set according to the requirements when leaving the factory. Please
contact our company if resetting is required)
Overload long-delay inverse time protection, short-circuit short-delay fixed time and inverse time protection, short-circuit instantaneous
protection, grounding or leakage current fixed time and inverse time protection, N-phase protection, current imbalance protection caused by
disconnection, load inverse time monitoring and other protection functions.
● Measurement and operation monitoring
Real-time measurement of various power grid operating parameters, such as frequency, power factor, and active power; real-time indication of
running status, such as fault status, alarm status, system self-diagnosis status, and normal running status.
● Inquiry
Running parameter inquiry, protection parameter setting value inquiry, historical fault record inquiry, self-diagnosis fault information inquiry and
power grid measurement parameter inquiry.
● Parameter setting
The following protection parameters can be directly set on the controller panel: Current value and time value of overload long-delay protection,
inverse time current value of short-circuit short-delay protection, fixed time current value and time value, current value of instantaneous
protection, current value and time value of load monitoring, set value of N-phase protection, current value, time value and inverse time
coefficient of grounding or residual current protection, imbalance rate and time value of current imbalance rate protection and harmonic
influence coefficient.
The following operations can also be performed on the controller panel: System clock calibration (only after this function is selected); setting all
the internal parameters of the system that can be set by the programmer (no programmer but the permission password is required).
● Programming interface
It provides the interface with the programmer to modify some specific parameters, such as function setting of output contacts, wiring mode of
voltage measurement, system clock, protection characteristic curve, thermal memory function, communication address, and communication
baud rate.
● Communication networking (this function is only available for Mic5.0 intelligent controllers)
The controller provides the standard RS485 interface, and can realize data transmission by Modbus or Profibus-DP or DeviceNet protocol, so as
to meet the requirements of telemetering, telesignaling, telecontrol and teleregulation of different monitoring systems.
● Test
The test functions are divided into two types: Instantaneous tripping simulation test and non-tripping simulation test:
(1) Instantaneous tripping simulation test: The tripping test of instantaneous operation of the circuit breaker can be carried out, and the inherent
operating time of the circuit breaker can be displayed after the operation.
(2) Non-tripping simulation test: The simulated test current is selected for the system non-tripping test. After the test is completed, the test
current, the system delay operating time under the test current and the fault category of the simulated test are alternately displayed.
● Self-diagnosis
It is used to diagnose and alarm some faults of the controller itself.
● Fault clock
It is used to record the time when the fault occurred. It can record the year, month, day, hour, minute and second of the fault occurred. (Up to 8
times can be recorded)
● Historical data record (optional)
It is used to record the four-phase current, three-phase voltage, frequency, power, power factor and active power, which can be recorded every
half hour for three months.
● Load monitoring protection
Load monitoring is used to control the different loads of the circuit breaker to ensure the power supply of the main load. Load monitoring can be
used for pre-alarm and branch load control. The controller can be programmed to output two passive signal contacts for load monitoring.
● MCR make-break and off-limit tripping (optional)
Make-break means that when the power grid is in a fault state before the circuit breaker is closed and the current greater than the MCR set
value is generated at the closing moment, the controller breaks the circuit breaker in an instantaneous way through the analog circuit. This
function only works at the closing moment (within 100 ms).
Off-limit tripping means that when the circuit breaker is in normal operation, and the short-circuit current exceeds a certain value (generally the
limit current of the circuit breaker), the controller breaks the circuit breaker in an instantaneous way through the analog circuit. This function is
not affected by the instantaneous set value.
● Communication protocol
It contains Modbus-RTU, which can be transferred to Profibus-DP or DeviceNet through an external module.

VI. Structure Overview
The circuit breaker is of compact structure and characterized by modularization. The contact system is enclosed between two insulation
baseboards with partition structure, and the contacts of each phase are partitioned to form independent chambers. The intelligent controller,
operating mechanism, manual and electric operating mechanisms are arranged in front of each other in turn to form their own independent units.
If one of the units fails, the unit can be completely removed for the replacement (see Figure 6 and Figure 7).

Figure 7 Drawer seat of the HYW3 Series Intelligent Universal Circuit Breaker
1: Draw-out circuit breaker
The draw-out circuit breaker consists of a circuit breaker body and a drawer. Guide rails are arranged on both sides of the drawer seat, which
have movable guide plates on them, and the main frame of the circuit breaker is placed on the left and right guide plates. The drawer circuit
breaker is connected to the main circuit by inserting the busbar on the breaker body into the bridge contact on the drawer seat. Through
cranking the handle of the lower beam of the drawer seat, three working positions of the drawer circuit breaker can be realized (there is a
position indication beside the handle).
“Connection” position: The main circuit and the secondary circuit are connected.
“Test” position: The main circuit is disconnected and separated by an insulating plate. Only when the secondary circuit is connected, the
necessary operation test can be carried out.
“Disconnection” position: The main circuit and the secondary circuit are all disconnected. If the circuit breaker body needs to be removed in
the “Disconnection” position, the rocker handle must be removed.
The draw-out circuit breaker has a mechanical interlocking device, which can only make the circuit breaker closed at the connection position or
the test position. It cannot be closed in the middle of the connection and test positions.
2: Interlocking mechanism
The interlocking mechanism is installed on the right side plate of the circuit breaker. The flat circuit breaker is interlocked by the steel cable
(Figure 8), and the stacked circuit breaker is interlocked by the connecting rod (Figure 9). When one circuit breaker is in the closing state, the
other one cannot be closed. The interlocking mechanism is installed by the user.
