SONTUOEC professional in producing MCB SKD spare parts good quality and best price SDX3 type Miniature Circuit Breaker IEC60898.1 standard MCB:
Product Description:
SDX3-63 is used in lighting distribution system or motor distribution system for protection overload and short-circuit in the system. The product is neoteric in structure, light in weight, reliable and excellent in performance. It has high breaking capacity, can trip quickly, and its case and items are adopted by high fire-resistant and shockproof plastics. The product, with long life, is mainly used in AC 50Hz/60Hz single-pole 230V or two, three, four pole 400V circuit for overload and short-circuit protection as well as for unfrequent on-and-off switching electric equipment and lighting circuit in normal case.
Function and Feature:
1.Protection against both overload and short circuit, the function of isolation
2.High short circuit capacity
3.Pin/fork type busbar terminal connecting
4.18mm DIN rail mounting and screw mounting
5. Full range accessories are available.
