Product Description
Product Description
Miniature circuit breaker SEB1-63
The SEB1-63 high breaking capacity miniature Circuit Breaker features advanced and proper structure, reliable performance, high breaking capacity, small and beautiful appearance. Its case and otehr components are made from impact resistant, high flame- retardant material. It's suitable for sites in which AC 50Hz or 60Hz with a rated operating voltage that is below 400V and a rated current from 3A to 63A is used, such as the illumination in office buildings, residential buildings and other similar buildings, the overload or short cirucit protection in distribution circuis and equipment. It may also be used as infrequent breaking and switching purposes for circuits under normal cirumstances.
Standards complied by this product: IEC60898 and GB10963.

Structural Characteristics
The SEB1-63 high breaking miniature circuit breker consists of a plastic case, operating mechanism, contact arc extinguishing system, tripping mechanism and other components. The case is made of high flame-retardant, high strength special plastic with the advantages of high impact resistance and light weight. The operating mechanism in the circuit breaker adopts high strength plastic materials to acquire the lowest moment of inertia while ensuring its sensitivity and reliability at the same time, minimizing the time from the start of the short-circuit fault to the actuation of the tripping mechanism. The tripping mechanism consists of two parts: the bimetallic overload reverse time tripping mechanism and the short circuit instantaneous electromagnetic mechanism. The contact are extinguishing system is equipped with a special arc angle and arc extinguishing chamber with significant current limiting characteristics.
