Built for legacy commercial systems, the Siemens HE3B060 is a 60A, 3-pole molded case circuit breaker delivering reliable thermal-magnetic protection. This bolt-on MCCB mounts into Siemens P1, P2, and P3 panelboards. Offering an exact physical match for older installations, it requires no adapters and serves as an exact cross-reference to the newer HED43B060 substitute. Rated for 25kAIC at 480VAC, it features fixed long-time and instantaneous (LI) trip functions to defend against overloads.

Product FAQs
5 answers
Can I install the HE3B060 in a standard residential load center?
No, the HE3B060 is a bolt-on molded case circuit breaker designed specifically for commercial and industrial Siemens P1, P2, and P3 panelboards and switchboards. It is not compatible with plug-on residential load centers.
Is there a modern replacement for the legacy HE3B060 circuit breaker?
Yes, the HED43B060 is the modern, exact physical substitute for the HE3B060. It mounts directly into the same Siemens panelboards without requiring any adapters.
Can the HE3B060 be reverse fed?
Yes, because the HE3B060 features a non-interchangeable thermal-magnetic trip unit and lacks specific Line and Load markings, it is suitable for reverse-feed applications.
Does the HE3B060 require a separate mounting kit for Siemens panelboards?
No, the HE3B060 is a bolt-on breaker that mounts directly to the bus of compatible Siemens P1, P2, and P3 panelboards without the need for an additional mounting kit or adapter.
Is the HE3B060 compatible with single-phase systems?
Yes, although it is a 3-pole breaker designed for 3-phase systems, it can be safely used in single-phase applications by wiring across two of the poles. However, a dedicated 2-pole breaker is typically preferred to conserve panel space.
