6NTB Miniature Circuit Breaker
Micro Circuit Breaker Series is a widely used terminal protection device in electrical terminal distribution systems. It is suitable for circuits with alternating current of 50/60Hz, rated voltage of 230/400V and rated current up to 125A, mainly used for overload and short-circuit protection, and also can serve as non-frequent operation conversion for circuits under normal conditions, which is extensively applied in industrial facilities, commercial buildings, high-rise structures and residential premises. Its structure consists of a contact system, an arc extinguishing device, an operating mechanism and a housing. The contacts and current-carrying components of the contact system are mostly made of electrolytic copper or silver alloy; the arc extinguishing device absorbs and cools electric arcs through metal arc-separating plates to achieve arc extinction; the operating mechanism is equipped with a solenoid magnetic release device and a bimetallic thermal release device; the housing is molded from thermoplastic insulating materials with excellent mechanical, heat-insulating and insulating properties.
