Load isolating switch 4P 380VAC 250A
General
TOGL series is a simple arc extinguishing device, which can carry the load point and control the electrical appliances of the combined circuit. It can turn on and off a certain load current and overload current, but it cannot break the short-circuit current. It must be used in series with a high-voltage fuse, and the short-circuit current can be cut off by means of the fuse.
