Product FAQs
7 answersCan the Siemens HED42B100L replace an older ITE breaker with the same catalog number?
Yes. Siemens acquired ITE and continued manufacturing the SENTRON ED frame series. A modern Siemens HED42B100L is a direct, exact replacement for an older ITE breaker bearing the same catalog number.
What does the L suffix in the HED42B100L catalog number indicate?
The L suffix indicates that this circuit breaker comes factory-equipped with standard line and load side lugs.
Is the HED42B100L compatible with standard residential load centers?
No. This is a unit-mount, feed-thru molded case circuit breaker designed for industrial and commercial applications. It mounts directly to a backpan in enclosures, switchboards, or motor control centers and is not a plug-on breaker for residential panels.
Are the trip settings on the HED42B100L adjustable?
No. This breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection functions that cannot be field-adjusted.
What does the H in the HED42B100L catalog number stand for?
The H designates this as a High Interrupting capacity breaker within the Siemens ED frame family. It provides a 42kAIC rating at 480V, which is significantly higher than standard ED4 breakers.
Does the HED42B100L provide ground fault or arc fault protection?
No. This is a standard thermal-magnetic circuit breaker designed strictly for overload and short-circuit protection. It does not include GFCI or AFCI functionality.
How is the HED42B100L mounted inside an enclosure?
This is a unit-mount breaker, meaning it is bolted directly to the mounting surface or backpan of the enclosure. Wire connections are then made directly to the provided line and load lugs.
