Product FAQs
6 answersIs there a modern equivalent for the legacy EC3030 breaker?
Yes, the Eaton EHD3030 is the direct modern replacement. It shares the exact same Westinghouse E-Frame footprint and electrical specifications for seamless retrofitting.
Can I install this breaker in a standard residential load center?
No, the EC3030 is a commercial-grade molded case circuit breaker designed exclusively for Cutler-Hammer Type EC panelboards. It will not fit in standard residential load centers.
Does the EC3030 snap into the panel?
No, this is a bolt-on circuit breaker. It must be mechanically bolted to the busbar of a compatible Cutler-Hammer Type EC panelboard.
Are the trip settings adjustable on the EC3030?
No, this breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
Can the EC3030 be used to protect HVAC circuits?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
Do the terminal lugs require specific wire materials?
The integrated load-side lugs are dual-rated for both copper and aluminum (Cu/Al) conductors ranging from 14 AWG to 1/0 AWG.
