2 Pole 63A MCB DZ47-63

Introduction:

As a critical protective and control device within low-voltage small-scale power distribution systems, the 2-pole 63A Miniature Circuit Breaker (MCB) is capable of rapidly and automatically interrupting the circuit in the event of overload or short-circuit faults, thereby effectively mitigating safety hazards such as equipment damage and fire.
Our 2‑pole 63A miniature circuit breaker features Class‑A flame‑retardant housing, effectively preventing fire risks under high‑temperature conditions.
The tripping characteristics of miniature circuit breakers are categorized into three curves—B, C, and D—to suit various application scenarios: Type B is primarily used for residential power distribution; Type C is suitable for small motors and commercial electrical systems; and Type D is predominantly applied in industrial environments.
Our 2P 63A miniature circuit breakers are widely applied in residential lighting, main power switches, public buildings, industrial distribution rooms, new energy projects, public service facilities and 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.
CNTN Electric manufactures 2 Pole 63A MCB with high reliability and quality. The rated current (A) of these miniature circuit breakers ranges from 6 A to 63 A, and the rated voltage is 5-220 VAC.
