The NB3P100 is rated at 10kA interrupting capacity at 120/240V. This is adequate for most residential and light commercial services where the available fault current does not exceed 10kA. For larger commercial installations or services fed from high-capacity transformers, you should verify the available fault current with your electrician or engineer before selecting this breaker.
The NB3P100 is a 100A 3-pole bolt-on breaker suitable for use as either a main disconnect or a branch/feeder breaker, depending on the panel configuration and how your system is designed. Suitability as a main breaker depends on your specific enclosure and local code requirements — we recommend confirming the intended application with a licensed electrician and checking with us on panel compatibility.
