Engineered for commercial and industrial power distribution, the Siemens HED41B060 is a 1-pole, 60A molded case circuit breaker from the Sentron ED frame series. It provides reliable thermal-magnetic protection with a high interrupting capacity of 100kA at 120VAC and 25kA at 277VAC. This unit mounts into Siemens P1, P2, and P3 panelboards, as well as SB switchboards. For newer installations, this legacy-style breaker is replaced by the 3VA5160-6ED16-0AA0, which requires a mounting kit.

Product FAQs
6 answers
Which panelboards are compatible with the Siemens HED41B060 circuit breaker?
The HED41B060 is designed for use in Siemens Sentron panelboards, including P1, P2, and P3 models, as well as SB switchboards. It requires a bolt-on connection.
What wire sizes and materials are accepted by the lugs on the HED41B060?
The factory-installed lugs on this breaker accept 10 AWG to 4 AWG wire, and are rated for both copper (Cu) and aluminum (Al) conductors.
How does the interrupting rating of the HED41B060 differ between 120V and 277V applications?
The HED4 frame provides high interrupting capacity, delivering 100kAIC at 120VAC and 25kAIC at 277VAC. This makes it suitable for commercial distribution systems requiring higher fault current protection than standard ED4 breakers.
Can the HED41B060 replace older ED frame circuit breakers?
Yes, the HED41B060 is part of the Siemens ED frame family and can replace older standard ED4 or legacy ITE breakers of the same physical size, provided the panelboard accepts bolt-on connections and the interrupting rating meets or exceeds your system requirements.
Is the trip unit on the HED41B060 adjustable?
No, this breaker features a fixed thermal magnetic trip unit with long-time and instantaneous (LI) trip functions. It cannot be adjusted in the field.
What safety precautions should be taken when installing this bolt-on MCCB?
Always de-energize the panelboard or switchboard before installation. Verify that the system voltage does not exceed the 277VAC maximum rating, and ensure the bolt-on connections are torqued to the manufacturer specifications to prevent arcing or overheating.
