Product Description
Mining Explosion proof Starter (QJZ-400soft)

1. Function

This series mine explosion-proof and intrinsically safe type vacuum electromagenetic starter
Is applicable in AC 50Hz distribution system with rated voltage of 1140V or 660V in
Underground coal mines with explosive and dangerous gas(methane) and coal dust. It is
Used to control the direct start and stop and reversal of three-phase squirrel-cage
Asynchronous motor with rated current of 400A, 315A and 200A, meanwhile, it also offers
Protection to motor and relative circuit. The starter can be connected with methane poweroff
Instrument, when it is overrun, the starter will switch off to realize power off.

2. Characteristics

2.1 Real-time English display for voltage, current, switching on and off and fault state
2.2 Standard RS485/232 communication interface
2.3 Multiple Protective functions for overload, short circuit, under voltage, over voltage,
Loss of phase, leakage lockout, three-phase imbalance etc.
2.4 The intrinsically safe control system can conveniently realize long distance control.
Single set, sequential control, combined control, and the start and feedback delay time
Is adjustable.
