low voltage Circuit Breaker 10KA High Breaking Capacity up 100A IEC60947.2 110V, 240V MCB

Voltage Circuit Breaker 10KA High Breaking Capacity up 100A IEC60947.2 110V, 240V MCB

General

STQC series high breaking capacity mini circuit breaker is used in AC50/60Hz, rated voltage of 240V

1,2 poles 415V, rated current to 60A 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.

 

1. Technical data of the network at the point considered

The earthing systems,short-circuit current at the circuit breaker installation point,which must always be less than the breaking capacity of this device,network normal voltage.

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.)
