MCB 2 Pole 63a DZ47-63

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.
CNTN Electric’s 20 amps miniature circuit breaker is very compact in size, making it easy to install. Its overall dimensions are only 7.7*6.5*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.
