Product FAQs
5 answersWhich panelboards accept the EH2B100 circuit breaker?
This bolt-on breaker is compatible with Siemens P1, P2, and P3 panelboards. It is also backward compatible with legacy ITE panelboard enclosures.
What is the modern replacement for the legacy EH2B100?
The EH2B100 is a legacy E-frame breaker. For new installations or direct replacements, it has been superseded by the Siemens ED42B100 molded case circuit breaker.
What are the conductor requirements for the EH2B100 lugs?
The factory-installed load lugs accept wire sizes from 14 AWG to 1/0 AWG. They are dual-rated for terminating either copper or aluminum conductors.

Yes, the breaker is rated for DC applications up to 250VDC, where it delivers a 10 kAIC interrupting rating.
How does the trip unit operate on the EH2B100?
The breaker utilizes a non-interchangeable thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. This provides standard Long-Time and Instantaneous (LI) protection against overloads and short circuits.
