Molded Case Circuit Breaker for Lower Incoming Line 800V AC50/60Hz 400V 630A MCCB Hmkm1-630A 3p

HMKM1 series molded case circuit breaker (hereinafter referred to as circuit breaker) is one of the new circuit breakers developed by our company with international advanced design and manufacturing technology.

The rated insulation voltage is 800V, which is suitable for AC 50Hz, rated working voltage AC690V and below, infrequent switching in the circuit with rated working current of 800A and motor

For frequent startup. The circuit breaker is equipped with overload, short circuit and undervoltage protection devices, which can protect lines and power equipment from damage.

The circuit breakers are classified into L type (standard type), M type (high breaking type) and H type (high breaking type) according to their rated limit short-circuit breaking capacity (lcu). This circuit breaker

It has the characteristics of small volume, high breaking height, short flashover (zero flashover in some specifications), anti vibration, etc. It is an ideal product for land and ship use.

This series of circuit breakers can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally).

This series of circuit breakers have the isolation function, with the symbol of.

This series of circuit breakers meet the following standards:

GB14048.1 Low voltage Switchgear and Controlgear Part 1: General
