Description:
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
Advantages:
High breaking capacity , all rated current can reach 6KA;
Many kinds of accessories can be chosen, in modularize and flexibility combine that make the customer install conveniently;
The cover and function parts both are made of inflaming retarding, bear high temperature and bear impact plastic;
The breaker is applicable to lighting distribution system in industrial enterprise, commercially district, high-rise building and dwelling house.

Product Usage:
General rules for choosing MCB,For protecting cables and equipments against overload and short circuit.
a. Technical date of 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 ln) protection and control of the circuits against length cables in TN and IT systems.
C curve (5-10 ln) protection and control of the circuits against overloads and short-circuits; protecton for resistive and inductive loads with low inrush current.
D curve (10-20 ln) 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)
Working environment:
Working Temperature:-20 °C ~70°C
Heat Proof: Type 2(As temperature is 55°C,relative humidity is 95%)
Protective Grade: IP 20
Environment Protection
