EE3B100 - 100Amp Circuit Breaker

EE3B100 - 100 Amp Circuit Breaker

If you’re working with an existing system that calls for an EE3 frame breaker, the EE3B100 is a straightforward match. This is a 100 amp, 3-pole molded case circuit breaker built for typical commercial and light industrial power distribution. It’s rated at 10k A.I.C. at 240VAC, which puts it right in line with many standard applications where dependable circuit protection is required without overcomplicating things. This unit is designed to fit where an EE3 frame is already in place, so there’s no guesswork on compatibility. That’s usually the biggest concern in the field—getting something that drops in correctly and does its job. It operates at 40°C, which covers most indoor electrical environments like panelboards, switchgear rooms, and utility areas. Like other breakers in this class, it’s built to last and intended for consistent, everyday use protecting circuits from overloads and short circuits.
