Product Description

Product Description

Different shape Miniature Ciruit Breaker 6KA 1P 2P 3P 4P MCB for short-circuit and over-load protection with small tranparent cover marks and two plastic clips to fixed


General

STM22-63 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 50/60 frequency, Ue 400V and below, Ui 63A and below. And it is mainly applied at office building, residence, 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, which conforms to the standard IEC60898.1 and 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.
