The B1H2C5 – NOARK 2P 5A 480/277V DIN Rail Breaker offers reliable protection for your electrical circuits with a 10kA breaking capacity. Designed for efficient installation on standard DIN rails, this compact circuit breaker is ideal for various applications, ensuring safety and compliance in your power distribution system. Durable and dependable.
The B1H2C5 uses standard 35mm DIN rail mounting (EN 60715), making it quick to snap in and remove from compatible industrial enclosures and distribution boards. Despite 'bolt-on' appearing in some spec fields, this breaker's primary installation method is DIN rail — contact our team if you need clarification for your specific application.
Yes. Rated at 480/277V AC, the B1H2C5 is designed for commercial and industrial applications, including 480V wye systems where 277V appears line-to-neutral. Its 10kA interrupting capacity meets the fault-current requirements of many industrial control panels and distribution boards. Always verify the available fault current at your installation point does not exceed 10kA.
NOARK's B1H series can be difficult to locate through standard distribution channels, particularly in lower ampere ratings like 5A.
