Where It Works Best
The EH3B125 is well-suited for maintaining existing commercial and industrial electrical systems originally designed to use 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 125-amp, 3-pole breaker with the specified interrupting ratings. By matching the original form, fit, and functional characteristics, the EH3B125 helps preserve the intended operation of compatible legacy electrical equipment without requiring modifications to the existing installation.
