B1H3C16 – NOARK 3P 16A 480/277V DIN RAIL 10kA BREAKER

The B1H3C16 uses standard 35mm DIN rail mounting, making it compatible with industrial control panels, switchboards, and distribution enclosures equipped with DIN rail. It is not designed for residential loadcentres or plug-on busbar systems. If you're unsure whether your enclosure is compatible, contact our team with your enclosure model and we'll confirm.

The NOARK B1H3C16 may serve as a functional replacement for other 35mm DIN rail-mount 3-pole breakers of the same ratings (16A, 480/277V, 10kA), provided the physical dimensions and terminal configurations are compatible. Cross-referencing against the original breaker's frame and footprint is recommended. Reach out to our specialists — we can help verify suitability as a drop-in replacement.

A 10kA interrupting capacity (AIC) is suitable for many branch-circuit and feeder applications on 480V systems where the available fault current at the point of installation does not exceed 10kA. You'll need to verify the available short-circuit current (ASCC) at the breaker's location through a coordination study or by consulting your utility. If your system fault current exceeds 10kA, a higher-rated breaker will be required — our team can help you select the right option.
