Product details
product overview：
The JKM1 series plastic shell circuit breaker (hereinafter referred to as the circuit breaker) is a new type of circuit breaker designed and developed by our company using international technology. This circuit breaker has a small size and high breaking capacity. The characteristics of short arc and anti vibration make it an ideal product for land and ship use. The rated insulation voltage of the circuit breaker is 1000V (JKM1-80 is 800V), suitable for distribution networks with AC 50Hz/60Hz rated working voltage up to 1000V and rated current up to 1250A. It is used to distribute electrical energy and protect lines and power equipment from damage caused by overload, short circuit, and undervoltage faults. It can also be used for infrequent line switching and motor starting, as well as overload, short circuit, and undervoltage protection.
Circuit breakers can be installed vertically or horizontally.
G circuit breaker is suitable for isolation, represented by the symbol
The circuit breaker complies with the standard GB/T14048.2 "Low voltage switchgear and control equipment Part 2: Circuit breakers".
