B1H2C20 – NOARK 2P 20A 480/277V DIN RAIL 10kA BREAKER

The B1H2C20 uses standard 35mm DIN rail mounting (EN 60715), so it installs in any industrial control panel, distribution board, or switchboard enclosure fitted with a DIN rail. It is not designed for residential plug-in or bolt-on loadcentres. Its 480/277V rating makes it ideal for three-phase wye commercial and industrial distribution systems.

10kA AIC (Ampere Interrupting Capacity) is suitable for many commercial and light-industrial branch circuits where available fault current is at or below that level. For installations closer to a large transformer or main service, available fault current can be higher — you should verify the available short-circuit current at the point of installation with your engineer or authority having jurisdiction (AHJ) to ensure compliance with the Canadian Electrical Code (CEC).
