EB3020L - 20Amp Circuit Breaker

EB3020L - 20Amp Circuit Breaker

When you're maintaining an older electrical system, finding the right replacement breaker can be challenging. In many cases, the goal isn't to change the system—it's to keep existing equipment operating as designed. The EB3020L 20 Amp 3-Pole Type EB Thermal-Magnetic Circuit Breaker was built for exactly that purpose, providing a form, fit, and function replacement for compatible Type EB panelboards manufactured before 1989.

Designed to help protect electrical circuits from overloads and short circuits, the EB3020L combines a 20 amp rating, 3-pole configuration, and 10kA interrupting capacity at 240VAC in a breaker intended for legacy electrical distribution equipment. Its thermal-magnetic trip mechanism responds to both sustained overload conditions and sudden fault events, helping maintain protection for connected circuits and equipment. The breaker also includes both line and load terminals, which can simplify installation when replacing an existing unit in a compatible panelboard.
