Technical Specifications

Appearance and dimensions

The fuse group of isolation switch is a multi-pole, manually operated switch. The operating mechanism is an acceleration mechanism with spring energy storage and instantaneous release. The instantaneous connection and disconnection of the multi-terminal contact structure has nothing to do with the speed of the operating handle, which greatly improves various electrical and mechanical properties. The disconnector fuse group can ensure that the circuit is turned on and off with load, and has reliable safety breaking protection against overcurrent or short circuit, and the open state is clearly visible.
