1. Safety Information
Please make sure if the product is broken before installing.
Please check if all the control power, current, voltage are off before
connecting or taking apart.
The terminal has a high current and high voltage so it can be
life-threatening when you touch it directly.
The setting should be done along the distribution line configuration.
The machine shows wrong information or malfunction caused by a
different setting from the distribution line configuration.
Connect the side connector along correct connector number with
current/voltage/DO/DI.
The appliance’s earthing terminal should be earthed to ground.
Caution !
Before installing the product, please read the instructions.

2. Introduction
2.1. Summary
Reclosers are used in distribution system. In case of line fault, due to temporarily
overcurrent, Reclosers can break and make currents several times, thus avoiding longer
network interruptions due to temporary faults. But, in case of permanent fault, because
fault current is still detected after trip and reclosing actions of pre-set sequences, Recloser
is locked out finally as opened.
The pre-set sequences are available to set five times, and for both phase and ground, the
combined operations are possible within the range of 5 instantaneous or 5 times delayed
operating. The first interruption of a fault regarding instantaneous operation, is done
quickly and instantaneously, so that even the fuses in the system do not operate. After
setting time, it recloses back on. And the next interruption has a definite or inverse time
delay. Thus downstream fuses or other protection devices in the network have the chance
to operate and isolate the affected network section, restoring normal operation in the
remaining work. Therefore reclosers make the range of fault section to be limited.
Mainly Reclosers which are installed in overhead distribution line, provide the measurement
of electric current flowing in the distribution line. In case of load current occurrence and
fault detection, it opens and recloses repeatedly according to setting sequence, and at the
sametime, it transmits the status/receives the command to/from HOST and remote controls
of opening/reclosing to minimize the accident. Besides, it stores the whole events in
distribution line, provides the fault causes, and it performs remote monitoring and controls
by transmitting data through DNP3.0, IEC60870-5-101, IEC60870-5-104 protocols.
