EB1020L - 20Amp Circuit Breaker

EB1020L - 20Amp Circuit Breaker

The EB1020L is a 20 Amp, single-pole thermal magnetic circuit breaker commonly used in electrical panels and distribution equipment manufactured before 1989. When you're working with an older panel, the goal is usually straightforward: find a replacement breaker that matches the original design and keeps the system operating as intended. The EB1020L was built for exactly that purpose, helping maintain compatibility in existing EB panel installations without requiring changes to the panel layout or protection scheme.

Inside the breaker is a thermal-magnetic trip mechanism, a design that has long been used throughout electrical distribution systems. The thermal element responds to sustained overload conditions, while the magnetic element reacts quickly to short-circuit faults. Together, these functions help protect branch circuits and connected equipment during normal operation.

With a 20 Amp rating, 120VAC capacity, and 10kA interrupting rating, the EB1020L is well suited for many branch circuit applications found in legacy electrical systems. This version includes both line and load terminals, which can help make replacement work more convenient when servicing compatible panelboards and load centers.
