E3100 - 100Amp Circuit Breaker

E3100 - 100Amp Circuit Breaker

When you're maintaining an existing electrical distribution system, finding the right replacement breaker matters. The E3100 100 Amp 3-Pole Circuit Breaker is a Type E thermal-magnetic circuit breaker designed to provide dependable overcurrent protection in compatible three-phase electrical systems. With a 100-amp rating, 10kA interrupting capacity at 240VAC, and a non-interchangeable trip unit, this breaker is intended for applications where matching the original equipment specifications is essential.

The thermal-magnetic design combines two levels of protection in one device. The thermal element responds to sustained overload conditions, while the magnetic element reacts quickly to short-circuit events, helping protect connected equipment and electrical infrastructure. Rated for operation in environments up to 40°C (104°F), the E3100 is well suited for a wide range of commercial and industrial applications where consistent circuit protection is required.
