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.
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.)
