The B1H2C4 NOARK 2P 4A 480/277V DIN Rail Breaker offers reliable overcurrent protection with a compact design. Rated at 10kA, this two-pole breaker is ideal for both commercial and residential applications, ensuring efficient electrical management. Its easy installation on DIN rails makes it a perfect choice for your circuit protection needs.
The B1H2C4 mounts on a standard 35 mm top-hat DIN rail (EN 60715), which is the most common rail size used in commercial and industrial enclosures across Canada. It will not bus-stab into residential loadcentres. If you have a specific enclosure or panelboard in mind, send us the model number and we'll confirm compatibility before you order.
Yes. The NOARK B1H series is suitable for both branch-circuit overcurrent protection and supplementary (equipment) protection in control panels and machinery, provided the installation meets the 480/277 V AC, 10 kA interrupting-capacity requirements of your application and complies with the Canadian Electrical Code (CEC). Always verify your available fault current does not exceed 10 kA at the point of installation.
NOARK B1H series breakers are a current product line, but specific ampere/pole combinations — including low-amperage ratings like 4 A — can be difficult to source locally in Canada. Northern Breaker Group specialises in stocking hard-to-find and low-volume breakers. Contact us or visit one of our Calgary, Edmonton, or Vancouver counters for availability and a quote.
