Product FAQs
7 answersWhat panelboards are compatible with the E3015 circuit breaker?
The E3015 is a legacy bolt-on breaker designed to fit older Westinghouse and AB De-Ion panelboards, as well as compatible Eaton Pow-R-Line panels.
Are Eaton, Cutler-Hammer, and Westinghouse E3015 breakers the same?
Yes. Eaton acquired the Westinghouse distribution equipment business, so E3015 breakers labeled under the Eaton, Cutler-Hammer, or Westinghouse brands are physically and electrically identical.
Is there a newer replacement for the E3015 breaker?
Yes, the E3015 cross-references with the EHD3015, which is a newer E-frame equivalent that fits the same legacy panelboards.
How does the E3015 mount into the panelboard?
As a bolt-on molded case circuit breaker, the E3015 mounts directly to the panel bus on the line side and includes standard lug terminals on the load side for wire connections.
Can the E3015 breaker be used in DC electrical systems?
Yes, in addition to its standard AC ratings, the E3015 is rated for DC applications up to 250VDC with an interrupting capacity of 5kA.
What wire sizes do the load side lugs on the E3015 accept?
The standard load side lugs on this breaker accept wire sizes ranging from 14 AWG up to 1/0 AWG.
What type of trip unit does the E3015 feature?
It features a fixed thermal magnetic trip unit with long-time and instantaneous (LI) trip functions for standard overload and short circuit protection.
