General
ASJ10-GQ series Self-resetting over-voltage and under-voltage protector(referred to as ASJ) is suitable for
single-phase AC voltage 230V or three-phase voltage 400V, frequency 45-65Hz,Users or loads with rated
working current up to and including 63A. When the single-phase or three-phase line over-voltage or under
voltage is caused by the neutral line fault, the protective device is opposite to the electrical equipment
Protection.
ASJ series products have the functions of over-voltage, under voltage protection and automatic delay
reset of line normal voltage. The products are mainly used in the residential box The protection of incoming
line or single-phase or three-phase electrical equipment distribution line, with small volume, high precision,
compact structure and convenient installation, is the safety in the field of civil construction Full protection
device.

product features
■ auxiliary power supply AC230V (phase voltage).
■ cut off the line in case of over-voltage and under voltage, reset the line automatically after the line voltage
returns to normal, and connect the line without manual operation.
■ voltage measurement range: AC50v-290v, frequency 50Hz ± 5Hz, product power consumption is not more
than 3W.
■ impulse withstand voltage: 4KV.
■ the working state is indicated by the two-color diode of the protector, the green light is normally on - the
voltage is normal; the red light is fast flashing - over-voltage; the red light is slow flashing - under voltage;
the red light is normally on-Open phase / fault.
■ output capacity of relay: it can withstand the over-current of 120% current level of shell frame.
■ wiring mode: up in down out.
■ electrical life: 10000 times.
■ the product is installed on the outgoing side of the main switch of the household box.
