Square D EH34015 Three Pole Plug-In Circuit Breaker

The Square D EH34015 is a 15-amp, three-pole plug-in circuit breaker designed for 480Y/277 VAC three-phase electrical systems. It provides thermal-magnetic overload protection for branch circuits in commercial or light-industrial panelboards that accept plug-in devices, making it suitable for protecting motors, pumps, conveyors, and HVAC components fed from a 480Y/277 VAC supply. With its three-pole configuration and plug-in mounting, this model is intended for use in compatible Square D panels that operate at 480Y/277 VAC, offering reliable protection across three conductors in a single device. This part is identified by the EH34015 model number and is used in installations requiring a 15-amp protection device for three-phase 480Y/277 VAC circuits.
