JN15-12/31.5kA-210 Earthing Switch with High Voltage Switchgear
The maximum rated current is only 630A, and the circuit breaker can reach 3000A above(there are more than 4000A in foreign countries). The maximum rated current is only 630A, and the circuit breaker can reach 3000A or above(there are currently more than 4000A in foreign countries). The circuit breaker is usually short-circuit-protected. In case of overload, it takes a certain time(and can not be adjusted unless the internal fuse is replaced) to cut off the hot fuse of the internal fuse of the circuit, and the inner voltage switch is used to protect the overload of the device Or sulphur hexafluoride load switch.
