Products Description
HD-30 is a new generation of circuit breakers for small and precision equipment, with hydraulic electromagnetic structure. This advanced structure is mainly composed of operating mechanism,contact, decoupling mechanism, etc. It has strong impact resistance, high flame retardant and other characteristics. It is a kind of current-limiting high-sensitivity miniature circuit breaker with dual protection of over-current and short-circuit.
The circuit equipment protector is a fully sealed structure, adopting copper contact, longitudinal magnetic field structure. It is equipped with the latest designed permanent magnet and spring energy storage operating mechanism. It is simple in structure and reliable in operation.
HD series hydraulic electromagnetic circuit breaker is suitable for AC 50/60HZ, rated voltage 250V and rated current 0.5-100A electrical system. It is used as the on-off operation of circuits or equipment, and used to protect circuits and motors from overload and short-circuit. It’s particularly suitable for occasions with impact or vibration, and also gasoline generator sets.
