RDM1L molded case circuit breaker is extensively used in the power distribution network of AC 50/60Hz and with rated voltage of 400V and rated current up to 800A. This electrical switch can protect people against direct contact with dangerous electric current and prevent fire disaster caused by false circuit connection and ground fault, etc. It can also be used to distribute electric power and protect power equipment against damage caused by overload and short circuit, and can change the circuit and start the motor infrequently.
This molded case circuit breaker is in conformation with IEC60947-2 standard.
