Description
The N-B1H3C10 is a miniature circuit breaker (MCB) from Noark Electric’s B1H series, designed for branch circuit protection in industrial and commercial applications. It features a 3-pole configuration, a 10A rated current, and a C-curve tripping characteristic, which means it trips at currents between 5 to 10 times the rated current—ideal for resistive and inductive loads like motors and lighting. This breaker is UL 489 listed, with a 10kA interrupting capacity at 480Y/277 VAC, and mounts on a standard 35mm DIN rail. It uses box lug terminals and supports wire sizes from #18 to #4 AWG. The toggle includes a red/green contact position indicator, and the unit can be padlocked in either ON or OFF position for safety.
