The B380H – SIEMENS 3P80A 240V Bolt-On Breaker is designed for reliability and performance in demanding electrical applications. With a robust 22kA interrupting capacity, this 80-amp three-pole breaker provides superior protection for your circuits and components. Perfect for commercial or residential setups, it ensures safety and efficiency in your electrical systems.
The 'H' suffix on the B380H typically denotes an enhanced or higher interrupting rating variant within the Siemens B series. The B380H is rated at 22kA, which may exceed the rating of a base B380. You should always match or exceed the AIC rating required by your panel's short-circuit current rating (SCCR) — if your panel or local fault current demands 22kA, the B380H is the correct choice. Check your panel's label or consult a licensed electrician if unsure.
Availability of specific Siemens B-series bolt-on breakers can vary, and some variants have become hard to find through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — contact us with your part number and quantity and we'll let you know what we have in stock or can source for you.
The B-series bolt-on design is primarily intended for commercial and light industrial panelboards that accept bolt-on style breakers (such as Siemens/ITE EQ, ES, PL, and PN series). It is not a plug-in breaker and will not fit standard residential plug-in loadcentres. If you're replacing a breaker in a commercial panel, this is the correct type — but send us your panel model and we'll confirm it's the right fit.
