STM22-63   Miniature Circuit Breaker​

 

STM22-63 series high breaking capacity mini circuit breaker is used in AC50/60Hz, rated voltage of 230V

3, 4 poles 400V, rated current to 63A for overload and short-circuit protection as well as for unfrequented switching under normal case.It is used extensively for industry, commercial and household.This product conform to IEC60898 standard.


 
General
1. Application:For protecting cables and equipments against overload and short circuit.
2. General rules for choosing MCB.

1.) STM22-63 series miniature circuit breaker is mainly used for protection against overload and short circuit under the AC 50Hz/60Hz, reted voltage 230V/400V and rated current from 1A to 63A.

It also can be used for non-frequent on-and-off switch operation under normal circumstance.

1. In complicance with IEC/EN60898-1
2.With indicator function in the contact position.
3.Transparent cover designed to carry label.
4.Bilateral busbar wiring capabilities to adapt to the wider use of premises.
5.Maximum connecting ability of 25mm2, wiring torque 3N*m, applicable to a variety of installing equipments, wiring stronger
6.Protection calss: IP20

7. Guarantee: 2 Years 

 

2).There are 3 curvve characteristics for magnetic operation:

B curve (3-5In) protection and control of the circuits against length cables in TN and IT systems.
C curve (5-10In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
D curve (10-14In) protection and control of the circuits against overloads and short-circuits; protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers,breakdown lamps.)
