KNM1L
Korlen
KNM1L series residual current circuit breaker are applies at the power distribution network of AC 50/60Hz, rated operation voltage of 400V(690V) and below, and rated current up to 800A. They can also be us to 800A. They can protect people against indirect contact and prevent tire disaster caused by insulation and ground fault. They can also be used to distribute electric power and protect power equipment against overload and short-current, and can change the circuit and start motor infrequently.
According to the actual situation, the rated residual operating current and residual current operating time be locally adjusted; The creepage protection moudule stil normally operate, even phase voltage reduces to 50V; Creepage alarm output function.
This product conforms to the requirement of IEC60947-2, GB14048.2 standards.
