KNM5 Series 10–800A AC690V Moulded Case Circuit Breaker

KNM5 series moulded case circuit breaker the rated insulation voltage of the circuit breaker is up to 1000V. It is suitable for AC 50Hz, rated working voltage to 690V, rated working current 10A to 800A in the distribution network circuit, used to distribute power and protect the line and power equipment from overload, short circuit, or damage to voltage and other faults. At the same time, it can also be used as the initial infrequent start of the motor and overload, short circuit and under voltage protection. The circuit breaker has the characteristics of small size, high breaking, short arcing, etc., and is an ideal product for users. The circuit breaker is installed vertically. This product complies with EC60947-2, GB14048.2 and other standards.
