Where It Works Best
The EH3B100 is a practical choice for maintaining existing commercial and industrial electrical systems originally designed for an EH3 molded-case circuit breaker. It is commonly used in panelboards, switchboards, motor control equipment, and other three-phase power distribution systems requiring a 100-amp, 3-pole breaker. By matching the original form, fit, and electrical ratings, this breaker helps keep compatible equipment operating as intended without altering the existing system design.
