HKM1E series intelligent molded case circuit breakers (hereinafter referred to as circuit breakers) are high-tech products for the 21st century. The product has advanced design, reliable performance, high technical indicators, beautiful appearance, small size, uses microelectronic technology, and has intelligent overcurrent protection function.
△ The circuit breaker is suitable for power systems with dry AC 50Hz, rated voltage 400V, and rated current up to 800A. It is used to distribute electric energy and protect lines and power equipment from overload, short circuit, undervoltage and other faults. It can also be used to control the infrequent operation of motors.
△ The intelligent overcurrent release of the circuit breaker is controlled by a microprocessor and has three-stage protection characteristics, namely overload inverse time long delay protection, short circuit delay protection and short circuit instantaneous protection. Due to the adjustable artificial short-circuit short-delay protection characteristics, this series of circuit breakers can clearly achieve selective protection with another short-circuit protection device connected in series on the load side.
△ The three-stage overcurrent protection characteristics of the circuit breaker can be easily adjusted to meet the requirements of different loads for protection characteristics and achieve the best match.
△ The circuit breaker has operation, pre-alarm indication and overload indication.
