EB3100L - 100Amp Circuit Breaker

EB3100L - 100Amp Circuit Breaker

Keeping older electrical systems operating safely often comes down to finding the right replacement components. The EB3100L Type EB circuit breaker is a 100 amp, 3-pole thermal-magnetic circuit breaker designed for use in compatible Type EB panelboards manufactured before 1989. Whether you're performing routine maintenance, replacing a failed breaker, or supporting a long-standing facility, this breaker helps preserve the original design and functionality of your existing electrical distribution equipment.

The EB3100L combines overload and short-circuit protection through its thermal-magnetic trip mechanism, helping safeguard connected equipment and circuits from common electrical faults. With a 10kA interrupting rating at 240VAC, it is suited for a variety of commercial, industrial, and institutional applications where compatible legacy systems remain in service. The breaker features a non-interchangeable trip unit and comes complete with line and load terminals, making it a practical replacement option when maintaining existing Type EB installations.
