Engineered for commercial environments, the Siemens B115H is a 1-pole, 15A MCCB. It belongs to the BLH series, offering enhanced current-limiting capabilities. This device installs into Siemens P1 through P5 panelboards. The bolt-on configuration provides a secure connection, preventing loosening over time due to vibration. Rated to interrupt 22kAIC at 120/240VAC, it relies on fixed thermal-magnetic trip elements. It carries HACR and SWD ratings for HVAC and lighting circuits.

Product FAQs
7 answers
Which panelboards accept the B115H circuit breaker?
This bolt-on breaker is designed for installation in Siemens P1, P2, P3, P4, and P5 series panelboards.
Can the Siemens B115H replace older ITE or Gould breakers?
Yes. Siemens acquired ITE and Gould, and the current Siemens B115H serves as a direct replacement for legacy ITE or Gould breakers sharing the B115H catalog number.
What is the difference between the Siemens B115 and the B115H?
The primary difference is the interrupting capacity. The standard B115 has a 10kAIC rating, while the B115H features a higher 22kAIC rating for systems with greater available fault current.
Is the B115H rated for use with HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration motor group applications.
Does this breaker carry an SWD rating for lighting circuits?
Yes, the 15-amp B115H is SWD (Switching Duty) rated, meaning it is approved for switching fluorescent lighting loads on and off on a regular basis.
Are the trip settings adjustable on the B115H?
No, this breaker features fixed thermal and fixed magnetic trip elements for standard long-time and instantaneous overcurrent protection.
Can I use aluminum wiring with the B115H breaker?
Yes, the terminal lugs accept 12 to 10 AWG aluminum wire or 14 to 10 AWG copper wire. When using aluminum conductors, applying a listed joint compound is recommended to prevent oxidation.
