I. Overview of HKM1 Molded Case Circuit Breaker:

HKM1 series plastic case circuit breaker (HKM1 plastic case circuit breaker) is a new type of circuit breaker developed by international advanced design and manufacturing technology. With overload, short circuit and undervoltage protection devices, can protect lines and power equipment from damage.

According to its rated limit short circuit breaking capacity (lcu), HKM1 plastic case circuit breakers can be divided into four types: C type (economical type), L type (standard type), M type (higher type), H type (high type). HKM1 Molded Case Circuit Breaker (MCCB) has the characteristics of small size, high interruption, short flying fox and anti-vibration. It is an ideal product for land and ship use.

The plastic case circuit breaker can be installed vertically (that is, vertically) or horizontally (that is, horizontally).

The product meets the requirements of IEC 60947-2 and GB14048.2 standards.

2. Scope of application of plastic case circuit breakers:

HKM1 series plastic case circuit breakers are mainly used for 50 Hz (or 60 Hz) AC, 800V rated insulation voltage, 690 V rated working voltage and below, 1600 A rated current distribution network as overload, undervoltage and short circuit protection of distribution power and protection lines and power supply equipment, 400A shell level circuit breakers, also as overload, undervoltage and short circuit protection of motors. Under normal circumstances, it can be used for the infrequent switching of lines and the infrequent starting of motors.
