Product DescriptionChinese Factory STM15-63 Series Miniature
Circuit Breaker 10KA 1P 2P 3P 6A 63A 230/400V MCB for Overload
current and Short circuit ProtectionGeneral
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.Specifications

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).Our Pros:More than 20-year
