EB3020 - 20Amp Circuit Breaker

EB3020 - 20Amp Circuit Breaker

When you're maintaining an older electrical distribution system, finding the right replacement breaker is often less about finding the newest option and more about finding the correct fit for the equipment already in service. The EB3020 20 Amp 3-Pole Type EB Circuit Breaker was designed for use in compatible Type EB panelboards manufactured before 1989, making it a practical solution for facilities that continue to rely on proven electrical infrastructure.

This 20 Amp thermal-magnetic circuit breaker helps protect electrical circuits from overloads and short circuits while maintaining compatibility with legacy panel systems. Featuring a 3-pole design, a 10kA interrupting rating at 240VAC, and a non-interchangeable trip unit, the EB3020 is built to meet the original design requirements of compatible equipment. Because it includes load terminals, installation can be more straightforward when replacing an existing breaker in a properly matched application.
