Product FAQs

7 answers
Which panelboards are compatible with the EB1020 circuit breaker?

The EB1020 is a bolt-on E-Frame breaker designed for use in classic Westinghouse and modern Eaton Cutler-Hammer panelboards that accept E-Frame devices.

Can the EB1020 replace an older EHD1020 breaker?

Yes, the EB1020 functions as a direct drop-in replacement for the discontinued EHD1020 series in 120VAC applications.

Is the EB1020 rated for switching duty?

Yes, this breaker carries an SWD (Switching Duty) designation, meaning it is approved for safely controlling 120VAC fluorescent lighting loads on a regular basis.

What are the wiring requirements for the EB1020 load lugs?

The load-side terminals accept 14 AWG to 10 AWG wire and are rated for both aluminum and copper conductors.

Can the EB1020 be used in DC control circuits?

Yes, in addition to its 120VAC rating, this breaker is rated for up to 125VDC with a 5kA interrupting capacity, making it suitable for specific low-voltage DC applications.

What is the advantage of the bolt-on connection for this E-Frame breaker?

The bolt-on configuration physically secures the breaker directly to the panel busbar with screws, providing a highly reliable connection that resists loosening from vibration or thermal cycling.

Are the trip settings adjustable on the EB1020?

No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous (LI) fault clearing functions.
