Chinese Factory STM15-63 Series Miniature Circuit Breaker 6KA 1P 2P 3P 6A 63A 230/400V MCB for Overload current and Short circuit Protection
General
STM15-63 miniature circuit breaker is nice in appearance, reasonable in structure, sound in feature, high in breaking capacity and its shell and parts are made of material with impact resistance. It is mainly used in the line of 50/60Hz, rated working voltage to 230V/400V, and rated current to 63A as protection against overload and short-circuit. 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 complies with standard IEC60898-1.

Selection
·Technical data of the network at the point considered: short-circuit current at the circuit-breaker installation point, which must always be less than the breaking capacity of this device, etwork normal voltage.
·Tripping curves:
B curve (3-5In) protection for people and big length cables in TN and IT systems.
C curve (5-10In) protection for resistive and inductive loads with low inrush current.
D curve(10-14In) protection for circuits which supply loads with high inrush
current at the circuit closing (LV/LV transformers, breakdown lamps).
