Product FAQs
4 answersWhat panelboards accept the Siemens B115 circuit breaker?
The B115 bolts directly into Siemens P1, P2, P3, P4, and P5 series panelboards. Because it utilizes a bolt-on mounting configuration, it cannot be installed in standard plug-on residential load centers.
Does the B115 carry SWD or HACR ratings?
Yes, this breaker is both SWD (Switching Duty) and HACR rated. It is approved for switching 120V fluorescent lighting circuits and for use with commercial heating, air conditioning, and refrigeration equipment.
Is the Siemens B115 a direct replacement for older ITE B115 breakers?
Yes. Because Siemens acquired the ITE and Gould brands, the current Siemens B115 is the exact manufacturer approved replacement for older ITE B115 and Gould B115 bolt-on circuit breakers.
How much panel space does the B115 require?
As a standard BL series 1 pole breaker, it requires exactly 1 inch of space on the panelboard bus.
