Product DescriptionFactory Direct Sale STM10-63 Series 6KA
Miniature Circuit Breaker 1P 2P 10A 25A 63A 230/400V MCB for
Overload and Short Circuit ProtectionGeneral
STM10-63 Series 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 or 60 frequency, Ue 400V and
below, Ui 63A and below. It is mainly applied at office building,
residence, for 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. It conforms to the
standards IEC60898.1 and
GB10963.1Specifications Standard IEC/EN

General rules for choosing MCB:
a. 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.
b. There are 3 curve characteristics for magnetic operation:
*B curve (3-5 In) protection and control of the circuits against length cables in TN and IT systems.
*C curve (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and
inductive loads with low inrush current.
*D curve (10-20 In) 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).Our
