Product Title

CHINT NB1-63DC 32A 2P 500V DC Circuit Breaker

Short Description

The CHINT NB1-63DC 32A two-pole DC circuit breaker provides overload and short-circuit protection for compatible DC systems. The 2P version is officially rated at DC 500V and features Type-C tripping, 6kA breaking capacity, 4kV impulse withstand voltage, IP20 protection and DIN-rail installation.

Long Description

Designed for modern DC power distribution, the CHINT NB1-63DC combines reliable thermomagnetic protection with a compact modular enclosure. This listing is for the 32A, two-pole version rated at DC 500V. It is suitable for properly engineered photovoltaic arrays, battery energy-storage systems, telecommunications power supplies, EV-charging equipment and other compatible DC circuits.

The breaker delivers overload and short-circuit protection with Type-C instantaneous tripping at 7–10 times rated current and a 6kA rated short-circuit breaking capacity. Its dual-connection arrangement supports lead wire or compatible busbar connection, while the contact-position indicators and mechanically linked handle support clear operation and isolation. Installation must follow the official polarity and wiring diagrams and should be completed by a qualified electrical professional.
