EB3100L - 100Amp Circuit Breaker

EB3100L - 100 Amp Circuit Breaker

The EB3100L circuit breaker is a 3-pole, 100-amp thermal-magnetic circuit breaker designed for use in electrical distribution systems that require dependable overcurrent protection and compatibility with legacy panelboards manufactured before 1989. Built on the EB frame platform, this breaker features a non-interchangeable trip unit and is rated for 10kA interrupting capacity at 240VAC, helping protect circuits from overloads and short circuits in commercial and industrial environments. The EB3100L includes line and load terminals, making installation straightforward in compatible equipment. With a 40°C ambient temperature rating, it is intended for standard operating environments commonly found in electrical rooms, service panels, and equipment distribution systems. Designed for long service life, this breaker provides the proper form, fit, and function required when maintaining or servicing legacy electrical infrastructure.
