Wholesale & Quantity Pricing Tiers
The Chint NB1-63DC 2-Pole Miniature Circuit Breaker (MCB) is engineered engineered for high-performance protection in direct current (DC) electrical systems. Specifically designed to safeguard circuits against overloads and short circuits, this heavy-duty 2-Pole breaker is an essential component for solar photovoltaic (PV) systems, industrial automation, and DC distribution networks. With a robust design and global certifications, the Chint NB1-63DC ensures operational continuity and superior equipment protection under demanding electrical loads. Key Features & Specifications 1. Flexible Amperage Range Whether you are protecting delicate control circuits or high-power industrial lines, the NB1-63DC series has a variant for every load requirement. Available current ratings include: Low Load / Control: 1A, 2A, 3A, 4A, 6A, 10A Medium Load: 16A, 20A, 25A, 32A High Power / Heavy Duty: 40A, 50A, 63A 2. Specialized DC Engineering Unlike standard AC breakers, the NB1-63DC features integrated magnetic arc-extinguishing mechanisms designed explicitly for the unique behavior of direct current, preventing catastrophic failures and prolonging system life. 3. Dual-Pole Reliability The 2-Pole configuration provides comprehensive isolation by simultaneously interrupting both the positive and negative lines, offering complete circuit safety during maintenance or fault events. 4. Technical Breakdown Brand: CHINT Electric Model: NB1-63DC Number of Poles: 2-Pole Rated Voltage: Designed for high-voltage DC applications (Typically up to 500V DC / 1000V DC depending on system wiring). Mounting Type: Standard 35mm DIN Rail installation for seamless integration into existing switchgear panels and DB boxes. Targeted Applications Solar Photovoltaic (PV) Systems: Ideal for string combiner boxes and DC inverters to protect panels from reverse current faults. Battery Storage Infrastructure: Secures energy storage banks and UPS backup systems. Industrial Automation: Protects sensitive DC control circuits, telecommunication equipment, and manufacturing machinery. Electric Vehicle (EV) Charging Stations: Acts as a reliable safety barrier in DC fast-charging network setups.
