Description
Designed to support existing commercial infrastructure, the Eaton EB3035 is a 3-pole, 35A molded case circuit breaker. It delivers essential protection for legacy electrical distribution systems. This bolt-on breaker mounts into older Eaton and Westinghouse panelboards. It provides a perfect fit for aging enclosures, acting as a reliable substitute for EHD3035 and FD3035 models without adapters. Equipped with fixed thermal-magnetic trip technology, the breaker handles 10kAIC at 240VAC.Specifications

Product FAQs
8 answersWhich panelboards are compatible with the EB3035 circuit breaker?
This E frame breaker is designed specifically for bolt-on installation in legacy Westinghouse, Cutler-Hammer, and Eaton panelboards.
Can I replace an older Westinghouse EB3035 with an Eaton branded model?
Yes. Eaton acquired the Westinghouse electrical distribution line, making modern Eaton and Cutler-Hammer EB3035 breakers exact, interchangeable replacements for the original Westinghouse units.
Are the terminal lugs on the EB3035 rated for aluminum wire?
Yes, the factory lugs are dual-rated for both aluminum and copper conductors, accepting wire sizes from 14 AWG up to 1/0 AWG.
How does the thermal-magnetic trip unit protect the circuit?
The fixed thermal element provides long-time protection by responding to prolonged overloads, while the instantaneous magnetic element trips the breaker immediately during severe short circuits.
Can the EB3035 be used in direct current applications?
Yes, this breaker is dual-rated for both alternating current and direct current systems. It supports up to 250V DC with a 5 kA interrupting capacity.
Does this breaker plug into the panel bus?
No, the EB3035 is a bolt-on circuit breaker. It must be mechanically fastened directly to the panelboard busbars, which provides a highly secure connection suitable for commercial and industrial environments.
Is the EB3035 suitable for three-phase electrical systems?
Yes, it is a three-pole breaker designed to protect three-phase circuits up to 240V AC.
Can I adjust the trip settings on the EB3035?
No, this breaker features fixed thermal and fixed magnetic trip settings. The long-time and instantaneous trip functions cannot be field adjusted.
