Product FAQs
6 answersWhat panelboards are compatible with the EH3015 circuit breaker?
The EH3015 is a bolt-on molded case circuit breaker designed specifically for installation in Eaton and Westinghouse NEHB panelboards.
Are Eaton and Westinghouse EH-series breakers interchangeable?
Yes. Eaton acquired the Westinghouse distribution equipment division, meaning an Eaton EH3015 is an exact drop-in replacement for an original Westinghouse EH3015 in NEHB panelboards.
Does the EH3015 require separate mounting hardware for installation?
As a bolt-on breaker, the line side of the EH3015 bolts directly to the busbars of an NEHB panelboard. The load side includes factory-installed lug terminals for branch circuit wiring, so no additional terminal kits are required for standard installation.
Is the EH3015 suitable for direct current applications?
Yes, this breaker is rated for use in DC systems. It provides up to 10kA of interrupting capacity at 250VDC, making it a viable option for industrial control circuits or specialized equipment requiring DC branch protection.
Is the Westinghouse EH3015 obsolete?
The original Westinghouse-branded EH3015 is a legacy E-Frame breaker and is no longer manufactured under that name. However, Eaton continues to produce exact replacements under the Eaton and Cutler-Hammer brands to support existing NEHB panelboards.
What type of fault protection does the EH3015 provide?
The breaker utilizes a fixed thermal-magnetic trip unit with Long-Time and Instantaneous (LI) functions. The thermal element protects against gradual overloads, while the magnetic element trips instantly to clear severe short circuits.
