High Quality STM4-63 2p Mini Circuit Breaker with Ce Semko Approvals
General
STM4-63 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.
1. Application:For protecting cables and equipments against
overload and short circuit.
2. General rules for choosing MCB.
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.
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.
