The Noark B1B Miniature Circuit Breaker (MCB) series is designed for high-voltage DC circuit protection, featuring a 25-63 AMP range, 2-4 pole configurations, and a 10kA breaking capacity. With 500VDC protection for 2-pole setups and 1000VDC for 4-pole setups, these MCBs are ideal for solar power systems, battery storage, and industrial DC applications.

Engineered for reliable and efficient protection, the Noark B1B series utilizes a thermal-magnetic trip mechanism to safeguard circuits from overloads and short circuits. Their high-voltage capability makes them perfect for large-scale renewable energy projects, off-grid power systems, and EV charging infrastructure. With a compact, durable design, they are built for long-term performance and minimal maintenance.
