Product FAQs
6 answersWhat panelboards is the Siemens HB3B015 compatible with?
This breaker is designed for use in Siemens and ITE legacy panelboards, specifically Series 1 through 5.
What is the difference between Siemens BQ, BQH, and HBQ circuit breakers?
The primary difference is their interrupting rating. The standard BQ series is rated at 10kAIC, the BQH series is rated at 22kAIC, and the HBQ series offers a high interrupting capacity of 65kAIC at 240VAC. They share the same physical dimensions and bolt-on mounting style.
Can the HB3B015 replace a standard BQ3B015 breaker?
Yes, the HB3B015 has the exact same physical footprint and bolt-on connection as the standard BQ3B015. It can be used as a direct replacement or upgrade when a higher interrupting capacity of 65kAIC is required by the electrical system design.
What does the 65kAIC rating mean for the HB3B015?
The 65kAIC rating indicates that this breaker can safely interrupt up to 65,000 amps of fault current at 240VAC without sustaining damage. This high rating makes it suitable for commercial and industrial applications where high available fault currents are present.
Can I use aluminum wire with the HB3B015 breaker?
Yes, the lugs on this breaker are rated for both copper and aluminum conductors. When terminating aluminum wire, ensure you follow standard electrical practices and apply an appropriate joint compound to prevent oxidation.
Does this breaker provide GFCI or AFCI protection?
No, the HB3B015 is a standard thermal-magnetic circuit breaker. It provides essential overload and short-circuit protection but does not include Ground Fault Circuit Interrupter or Arc Fault Circuit Interrupter features.
