Product FAQs
7 answersWhich panelboards are compatible with the HE3B015 circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 commercial panelboards, as well as compatible switchboards. It is not intended for standard residential plug-on load centers.
Is the HE3B015 an obsolete or legacy breaker?
Yes, the HE3B015 is a legacy ITE and Siemens HE frame breaker. It is often replaced by newer ED frame breakers, such as the HED43B015, depending on panel requirements. However, exact replacements are still sourced for existing installations to avoid retrofitting.
What is the difference between the HE3B015 and the EH3B015?
The HE3B015 and EH3B015 share the same physical footprint and mounting, but the HE3B015 features a higher interrupting rating of 25kAIC at 480V compared to the standard EH frame. The HE3B015 can serve as a direct, upgraded replacement for the EH3B015.
Can the HE3B015 be used in DC electrical systems?
Yes, this breaker is rated for up to 250VDC with a 30kAIC interrupting capacity, making it suitable for specific direct current applications alongside its standard AC ratings.
Does the HE3B015 require a mounting hardware kit?
Yes, installing this bolt-on breaker into Siemens P-series panelboards typically requires a twin mounting hardware kit or strap kit specific to the panel type, such as P1, P2, or P3.
What does the LI trip function code mean on the HE3B015?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both the thermal and magnetic trip points are fixed on this model.
Is the HE3B015 suitable for HVAC or lighting loads?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment. It is also HID rated for high-intensity discharge lighting loads.
