1 / 7Circuit Breaker
MCB 2P DC 6鈥?3A Circuit Breaker
The Cnsoltree 2 Pole DC MCB is the most widely specified DC breaker for residential solar installations and battery energy storage systems. By breaking both the positive and negative conductors simultaneously, it provides complete galvanic isolation in a single switching action 鈥?eliminating the shock hazard that remains when only one pole is opened. Rated at 500V DC with 6kA breaking capacity, it handles the demanding fault currents generated by lithium-ion battery banks and high-voltage PV strings alike. The linked toggle mechanism guarantees that both poles trip together under overload or short-circuit conditions, meeting the safety requirements of IEC 60947-2 and T脺V PV certification. Backed by 18 years of manufacturing expertise and 100% pre-shipment electrical testing, the 2P DC MCB is available in nine current ratings from 6A to 63A 鈥?ready for everything from a single residential inverter feed to a parallel battery rack.
Key Features
- Simultaneous 2-pole disconnection 鈥?breaks positive and negative lines together for full galvanic isolation.
- 500V DC rated with 6kA breaking capacity 鈥?handles high fault currents from lithium battery banks.
- Linked toggle mechanism 鈥?both poles always trip together, preventing dangerous single-pole open states.
- Ideal for residential solar and ESS 鈥?the most popular configuration for home PV inverter protection.
- 9 current ratings (6A鈥?3A) 鈥?covers single-inverter feeds through parallel battery strings.
- 100% factory-tested trip accuracy 鈥?consistent C-curve performance across every production batch.
- OEM/ODM ready 鈥?custom branding, bilingual labels, and modified specifications for your market.
