Product Description

main features
SM1 series MCCB (hereinafter referred to as circuit breaker) is one of the new type circuit breakers developed and developed by adopting advanced international design technology.
According to the rated limit short circuit breaking capacity (lcu), it can be divided into L type (standard type), M type (higher type) and H type (high type).
The product has the characteristics of small volume, high breaking current, short arc and vibration resistance.
It is an ideal product for land and ship use. Its rated insulation voltage is 1000V (SM8-63 is 800V).

Summary
SM1 series plastic enclosure circuit breakers (hereinafter referred to as circuit breakers) are one of the new type of circuit breakers developed and developed with international advanced design technology. According to their rated limit short circuit breaking capacity (lcu), they are classified into L-type (standard type), M-type (higher breaking type) and H-type (high breaking type). The products have small volume and high breaking capacity. High breaking current, short arc, anti-vibration and so on, it is an ideal product for land and ship use. Its rated insulation voltage is 1000V (SM8-63 is 800V), suitable for AC 50Hz/60Hz, rated working voltage 690V and below in the circuit for non-frequent conversion and motor starting.
This series of plastic case circuit breakers have overload, short circuit and under-voltage protection devices to protect the line and power equipment from damage.
