The B1H1C5 NOARK 1P 5A 277V DIN Rail Breaker is a reliable protection solution for your circuits. With a 10kA interrupting rating, it ensures optimal safety and performance. Designed for easy installation on DIN rail systems, this compact breaker is perfect for residential and commercial applications. Trust NOARK for quality circuit protection.
The B1H1C5 mounts on a standard 35mm DIN rail (per EN 60715), so it is compatible with any DIN rail enclosure, industrial distribution board, or control panel that accepts 35mm DIN rail MCBs. It is not designed for plug-in residential loadcentres such as Siemens EQ or Square D QO panels.
277V AC is the line-to-neutral voltage of a 480V/277V three-phase, 4-wire wye system, which is common in Canadian commercial and industrial buildings for lighting circuits (fluorescent and LED fixtures). The B1H1C5 at 277V is ideal for protecting individual branch circuits on these systems.
Yes — NOARK B1H1 series MCBs are often used as modern replacements for legacy DIN rail breakers of the same pole, amperage, and voltage rating. Northern Breaker Group specialises in sourcing both current and hard-to-find breakers. Contact our Calgary, Edmonton, or Vancouver counter with your existing breaker's specs and we'll find the right replacement.
