Product FAQs
6 answersWhat is the modern replacement for the legacy EH2B020 circuit breaker?
The Siemens ED42B020 is the direct modern substitute for the legacy EH2B020. It shares the same E-frame footprint and bolt-on mounting configuration for seamless installation in older panelboards.
Which panelboards are compatible with the EH2B020 breaker?
This bolt-on molded case circuit breaker is designed specifically for use in legacy Siemens and ITE Type E2, F2, and P1 panelboards. It is not compatible with standard residential load centers or DIN rail systems.
Can the EH2B020 be used in DC power applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity. This makes it suitable for specific direct current systems alongside its standard 240VAC and 480VAC ratings.
What wire sizes are accepted by the load side lugs on this breaker?
The factory-installed lugs accept copper or aluminum conductors ranging from 14 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation to maintain a secure and compliant connection.
Is the Siemens EH2B020 interchangeable with older ITE versions?
Yes, Siemens acquired ITE, and the current EH2B020 is an exact match and direct replacement for the older ITE-branded EH2B020 or EH2-B020 breakers.
Are the trip settings adjustable on the EH2B020?
No, this breaker features fixed thermal and fixed magnetic trip elements. The long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
