The B1H1C13 – NOARK 1P 13A 277V DIN RAIL Breaker is designed for reliable circuit protection in a compact format. With a breaking capacity of 10kA, it ensures safety and longevity in electrical installations. Ideal for various applications, this breaker is perfect for both commercial and residential uses, providing peace of mind.
The B1H1C13 mounts on a standard 35 mm DIN rail (EN 60715 / TS 35) and is 17.5 mm wide for a 1-pole unit. It is compatible with most DIN rail enclosures and distribution boards that accept standard IEC-style MCBs. If you have a specific enclosure in mind, contact us and we'll confirm compatibility.
The 277V rating means this breaker is designed for single-phase branch circuits on a 480Y/277V commercial or industrial system (common in Canadian commercial buildings). While the voltage rating is a maximum and it will operate safely on lower voltages such as 120V or 240V, the B1H1C13 is a DIN rail IEC-style MCB and is generally not intended as a drop-in replacement for residential North American loadcentres. For residential applications, a different breaker type is typically required — contact us if you're unsure.
