The Siemens BF240 is a bolt-on style GFCI breaker from the BF/BL series, designed to fit Siemens/ITE bolt-on loadcentres and panelboards — including compatible EQ, ES, PL, and PN series panels that accept bolt-on (BA/BL/BF) breakers. It occupies 2 pole positions and is rated for 240V, 40A, 10kA AIC. Note that bolt-on breakers are not interchangeable with plug-in (QP/QT) Siemens loadcentres.

Yes — the BF240 is a very common choice for hot tub and spa installations. The Canadian Electrical Code (CEC) requires a GFCI-protected 2-pole breaker for hot tub circuits, and the BF240's built-in Class A ground fault protection at 40A/240V satisfies that requirement. Always verify your local authority having jurisdiction (AHJ) accepts the specific breaker model.
No — bolt-on and plug-in breakers are not interchangeable. The BF240 uses a bolt-on connection that physically bolts to the bus bar, used in Siemens/ITE EQ, ES, PL, and PN panelboards. Plug-in breakers (such as the QP or QPF series) snap onto a different style of bus and are used in Siemens PL/PN loadcentres designed for plug-in devices. Check your panel's bus type or label before ordering.
The BF-series bolt-on GFCI breakers can be difficult to locate through standard supply channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers and maintains stock of Siemens bolt-on devices.
