Description
Engineered for commercial and industrial applications, the Eaton EB3030 is a 3-pole, 30A molded case circuit breaker. It provides reliable protection for aging electrical systems. This bolt-on breaker mounts into legacy Eaton Pow-R-Line C and Westinghouse F-Frame panelboards. As an exact fit replacement, it eliminates retrofitting and substitutes the EHD3030. Featuring fixed thermal-magnetic trip technology, it is rated for 10kAIC at 240VAC and utilizes AB De-Ion arc extinction for safety.Specifications

Product FAQs
5 answersWhich panelboards accept the EB3030 circuit breaker?
This breaker is engineered for use in Eaton Pow-R-Line C panelboards and legacy Westinghouse F-Frame panelboards.
Is the Westinghouse EB3030 still manufactured?
No, the EB series is an obsolete legacy E-frame breaker. Eaton has replaced this line with current F-frame breakers, such as the EHD or FDB series, depending on your specific system voltage and interrupting requirements.
Can the EB3030 be applied in DC circuits?
Yes, it is suitable for direct current applications. It carries a maximum 250VDC rating with a 5kA interrupting capacity.
Do I need special lugs to use aluminum wire with the EB3030?
No, the factory-installed lugs are dual-rated for both copper and aluminum conductors. They accept wire sizes ranging from 14 AWG up to 1/0 AWG.
What are the advantages of the bolt-on mounting style for the EB3030?
Bolting the breaker directly to the panelboard bus ensures a rigid, high-contact connection. This prevents the breaker from loosening over time, especially in industrial environments prone to heavy vibration.
