RDM1L Molded Case Circuit Breaker
RDM1L molded case circuit breaker is extensively used inthe 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 directcontact with dangerous electric current and prevent fire disaster caused byfalse circuit connection and ground fault, etc. It can also be used todistribute electric power and protect power equipment against damage caused byoverload and short circuit, and can change the circuit and start themotor infrequently.
This moldedcase circuit breaker is in conformation with IEC60947-2 standard.
