nb1-63dc-1p-c10-125v chint 10a 1 pole c curve dc125v (solar) type miniture circuit breaker
Chint NB1-63DC-1P-C10-125V 10A single pole Type C DC miniature circuit breaker rated at 125V DC for overload and short circuit protection in solar, battery and DC distribution systems.
Why Choose the Chint NB1-63DC-1P-C10-125V DC Miniature Circuit Breaker?
The Chint NB1-63DC-1P-C10-125V is a dependable single pole Type C DC miniature circuit breaker (MCB) designed to protect direct current circuits against overloads and short circuits. As part of the Chint NB1-63DC Series, it is engineered for DC power distribution, solar PV systems, communication power supplies and battery-based installations where reliable fault protection is essential.
With a 10A current rating, Type C tripping characteristic and 125V DC rated voltage, the NB1-63DC-1P-C10-125V is suitable for low-voltage DC circuits with moderate inrush characteristics. Its compact DIN rail mounted design makes it easy to install inside distribution boards, solar combiner boxes, control panels and DC electrical enclosures.
Built for reliable DC circuit protection, this Chint MCB helps safeguard cables, connected equipment and power systems by automatically disconnecting the circuit when fault conditions occur. Its robust construction and modular format make it a practical choice for solar, telecoms, battery storage and industrial DC applications.
