Designed for heavy-duty commercial use, this 60A, two-pole ED-frame breaker delivers fixed thermal-magnetic protection. It utilizes an LI trip mechanism to secure critical circuits. The bolt-on design integrates seamlessly into Siemens Sentron, P1, P2, and P3 panelboards, plus SB switchboards. It includes LN1E100 load lugs and accepts 10-1/0 AWG wire. Delivering a robust 42kAIC at 480VAC, it meets stringent industrial requirements. Superseded by the 3VA5160-6EC26-0AA0.
Which Siemens panelboards are compatible with the HED42B060?
This bolt-on breaker is designed for use in Siemens Sentron panelboards, including P1, P2, and P3 models. It is also compatible with Siemens SB switchboards and motor control centers.
How does the HED42B060 differ from the standard ED42B060?
The HED42B060 is the high-interrupting capacity version of the standard ED42B060. It provides a 42kAIC rating at 480VAC, whereas the standard ED4 model is rated for 18kAIC at 480VAC. Both share the same physical ED frame footprint.
What wire sizes are supported by the standard lugs on this breaker?
The factory-installed lugs accept 10 AWG through 1/0 AWG copper or aluminum conductors. Always verify the required torque specifications printed on the breaker faceplate before terminating the wires.
Is the HED42B060 rated for direct current (DC) systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, where it provides an interrupting capacity of 30kA. This makes it suitable for specific industrial control and battery system panels.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the HED42B060 features fixed thermal and fixed magnetic trip settings. It does not offer field-adjustable trip dials for customizing the long-time or instantaneous pickup levels.
Does this breaker include ground fault or arc fault protection?
No. The HED42B060 is a standard thermal-magnetic breaker equipped with long-time and instantaneous (LI) trip functions. It does not provide equipment ground fault (EGFPD), GFCI, or AFCI protection.
Can this breaker be DIN rail mounted?
No, the HED42B060 is a bolt-on molded case circuit breaker designed to bolt directly to the busbars in compatible Siemens panelboards and switchboards. It is not designed for DIN rail installation.
What frame family does the HED42B060 belong to?
It is part of the Siemens ED frame family. Because it shares the standard ED frame dimensions, it can directly replace older or lower-rated ED frame breakers in existing enclosures without requiring hardware modifications.
