EB2050L - 50Amp Circuit Breaker

EB2050L - 50Amp Circuit Breaker

If you're maintaining an existing electrical system built around older EB panel equipment, finding the correct replacement breaker matters. The EB2050L is a 50 Amp, 2-pole thermal-magnetic circuit breaker designed specifically for use in compatible EB panelboards manufactured before 1989. Rather than modifying a panel or searching for alternative solutions, this breaker provides the form, fit, and function needed to help keep qualifying systems operating as originally designed.

The EB2050L combines thermal and magnetic trip protection to help safeguard electrical circuits from overloads and short-circuit conditions. Rated for 120/240VAC applications with a 10kA interrupting capacity, it is commonly used in commercial buildings, industrial facilities, institutional properties, and other locations where legacy electrical equipment remains in service. Because it includes both line and load terminals, installation is streamlined for qualified electrical professionals working on maintenance, repair, or replacement projects.
