It can effectively solve the issues with respect to high precision, reliability and cost. It has advantages of thermal circuit breakers without their disadvantages. Taking the stability of temperature into consideration, the hydraulic electromagnetic circuit breaker is not influenced by the change of environmental temperature. The hydraulic electromagnetic sensing mechanism only responds to the change of current in protection circuit. Neither does it have "heating" cycle to slow response to overload, nor does it has "cooling" cycle prior to its close again after overloading. When exceeding 125% of the full load value, it will trip. The delaying time of circuit breaker shall e enough long to avoid misoperation of tripping due to nondestructive instantaneous fluctuation. But when the malfunction occurs, the tripping of circuit breaker shall be as fast as possible. The delaying time depends in the viscosity of damping liquid and degree of overcurrent, and it varies from several milliseconds to several minutes. With high precision, reliability, universal purpose and solid functions, the hydraulic electromagnetic circuit breaker is the ideal device for automatic circuit protection,power conversion and circuit control of electrical and electronic appliances.
Hydraulic electromagnetic circuit breaker is applicable for making and breaking operation for circuit or equipment in AC50Hz or 60Hz electric system, with rated voltage 250V and rated current of 1A~100A, and is also applicable for protecting overload and short circuit of circuit and motor.
