Product FAQs
5 answersWhich panelboards are compatible with the Siemens B315H?
The B315H is a bolt-on circuit breaker designed for use in Siemens P1, P2, P3, P4, and P5 commercial panelboards. Because it requires a bolted connection to the busbar, it will not fit in standard plug-on residential load centers.
What does the "H" in the B315H catalog number indicate?
The "H" designates this as a high-interrupting breaker within the Siemens B-frame family. It provides a 22kAIC interrupting rating at 240VAC, which is higher than the standard 10kAIC rating found on the base B315 model.
What are the acceptable wire sizes for the B315H breaker terminals?
The terminal lugs accept 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire. Always refer to the side label on the breaker for exact torque specifications before terminating conductors.
Is the Siemens B315H circuit breaker HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires circuit protection with this specific designation.
Can the B315H replace older ITE circuit breakers?
Yes. Siemens acquired ITE, and the B315H is the direct replacement for older ITE brand breakers with the same B315H catalog number or those designated as 15A, 3-pole BLH type bolt-on breakers.
