Introduction :
- The 2-pole 63A Miniature Circuit Breaker (MCB) serves as a core component in low-voltage power distribution systems; in the event of an overload or short circuit, it automatically cuts off the power supply instantly, thereby preventing equipment damage and mitigating fire risks.
- Our MCB enclosures are constructed from Grade A flame-retardant materials, offering high-temperature resistance and fire-retardant properties to eliminate the risk of fires caused by high temperatures.
- Our compact circuit breakers feature three tripping curves—Types B, C, and D—to precisely match diverse electrical requirements: Type B is suitable for residential use, Type C is ideal for commercial applications and small motors, and Type D is specifically designed for industrial power systems.
- The MCB 2 Pole 63a manufactured by CNTN Electric is suitable for a wide range of applications, including residential lighting circuits, main incoming power supplies, public buildings, industrial power distribution rooms, new energy systems, public service facilities, and commercial office buildings.
- 20 ampères de CNTN Electric disjoncteur miniature est très compact, ce qui le rend facile à installer. Ses dimensions totales ne sont que de 7,7 x 6,5 x 1,7 cm.
- The 2P 63A Miniature Circuit Breaker from CNTN Electric features superior quality and reliable performance, with selectable rated currents ranging from 6A to 63A and a rated voltage of 5–220 VAC.
