EB1030L - 30Amp Circuit Breaker

EB1030L - 30Amp Circuit Breaker

The EB1030L is a 30 Amp, single-pole thermal magnetic circuit breaker commonly found in electrical panels and distribution equipment manufactured before 1989. If you're servicing an older electrical system, you know that replacing a breaker is often about maintaining compatibility rather than changing the design. The EB1030L was built for exactly that purpose, helping preserve the original panel configuration while providing the electrical ratings required for compatible EB installations.

This breaker features a thermal-magnetic trip mechanism, a long-established design used throughout electrical distribution systems. The thermal element responds to sustained overload conditions, while the magnetic element reacts quickly when a short-circuit fault occurs. Together, these functions help protect branch circuits, conductors, and connected equipment during normal operation.

With a 30 Amp rating, 120VAC capacity, and 10kA interrupting rating, the EB1030L is suitable for a wide range of branch circuit applications found in older electrical systems. This version includes both line and load terminals, which can help simplify installation and replacement work when servicing compatible panelboards and load centers.
