Commutation Switch
Mine Explosion-proof Commutation Switch
Applications
The commutation switch is suitable for infrequent manual switching on or off the circuit, the lamps and signal lights control as well as circuit measurement, with the AC frequent of 50Hz, rated voltage of 380V and rated current of 60A under the coal mine well with explosive gases (methane).
Features
1. The series of products are made up of the explosion-proof shell and commutation switch.
2. The explosion-proof shell is composed of shell, upper cap and terminal box, which are all connected with bolts in a flat explosion-proof way.
3. The upper cap of commutation switch is engraved with instruction of “closing” and “breaking”, which is respectively “I” and “0”.
