Product Description

 

Manufacturer Supply Customized Color MCB series Ac230V/400V Electric Miniature Circuit Breaker with transparent cover 6KA 1P,2P,3P,4P circuit breaker 
General

Application:

STM15-63  high breaking miniature circuit breaker has the features of structure advanced, performance reliable, breaking capacity high, appearance elegant and its shell and parts are made of material with impact resistance, strong flame-retardant feature.

It is suitable to power system of 50or 60 frequency ,Ue 400V and below, Ui 63A and below.

It is mainly applied at office building, residence, for lighting , power distribution and overload and short circuit protection of equipment. Normally, it also can be used as the not frequent transfer of power system. It conforms to the standards IEC60898and GB10963.1.

What is the difference between 2P and 1P+N of circuit breaker?

Prepresents the number of poles, N represents the zero line, 2P represents that both poles of the miniature circuit

breaker have thermal and magnetic protection functions, and the width is 36mm;
And 1P+N, only the hot wire thermal magnetic protection function, the N pole has no thermal magnetic

protection function, but it will be disconnected from the live wire at the same time, the width is 18mm;
Therefore, 1P+N is more economical than 2P, and it also has higher safety.

It is suitable for applications with small current such as lighting circuits.
