Sphere of application
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.2. Sphere of applicati
The rated insulation voltage of this Circuit Breaker is 750V which is applicable for theelectricity distribution net of AC 50Hz, rated working voltage 690V and below, rated workingcurrent from 6A to 630A. It is used to distribute electric power and protect the line and poweapparatus from being overload and short-circuit protection of the motor.This circuit breaker can be installed vertically and horizontally.This product complies with standard IEC60947-2.GB14048.2
