Product Description
1. Function

This series electromagnetic starter is applicable in AC50Hz power distribution system with
Voltage of 1140V(660V, 380V) in underground coal mines with explosive and dangerous
Gas(methane) and coal dust, and it is used to make automatic switching over control to dual
Power supply and dual dis-rotatory fan, realizing power distribution of dual power supply.
Automatic switching over operation mode of master-slave dis-rotatory fan, it ensures
Uninterrupted ventilation in underground coal mine for long time, and it is the most ideal
Control equipment for dual dis-rotatory fan for underground coal mine especially for heavy
Gas time.

2. Characteristics

2.1 Master-slave dual disrotatory fan and dual power supply for power distribution,
Automatic switching over
2.2 Switching over time is adjustable
2.3 Protective functions for short circuit, loss of phase, leakage lockout, over voltage,
Overload, phase imbalance etc.
2.4 Protective function for fan and power supply lock out
