Product Description
KBZ-400(200)/1140(660) Mining Explosion-proof Vacuum Feeder Switch


This mining explosion-proof type vacuum feeder switch is mainly used as low-voltage feeder switch for mobile substation (After the cover board is opened, it is oppositely connected with dry transformer) or main switch or branch switch in AC 50Hz power distribution system of indirect neutral-point earthing with voltage of 1140V or 660V and current of 400 A or 200A I underground coal mines with explosive and dangerous gas (methane) and coal dust and it is also made as big capacity motor of non-frequent start.

Cute square shell, convenient and flexible for movement
Multiple protective functions for overload, short circuit, loss of phase, electric leakage, leakage lockout, selective leakage(branch switch), over voltage, under voltage etc.
The operating mechanism adopts manual switching on or off, and it adopts electromagnetic tripping in fault state.

Technical Parameter:
Rated voltage(V): 1140/660
Rated current(A): 400/200
Limited making and breaking capacity(kA): 7.5/9/4.5
