Square D EHB34015 3 Pole 15 Amp Circuit Breaker

The Square D EHB34015 is a three-pole, 15-amp molded-case circuit breaker from Square D (Schneider Electric) designed for 480Y/277 VAC three-phase systems, featuring a bolt-on installation and Type EHB trip mechanism. This thermal-magnetic device is intended for use in NEHB panelboards, providing overcurrent protection for feeders and branch circuits in commercial and light-industrial installations that rely on 277/480 VAC distribution. It carries an interrupting rating of 14 kA at 480Y/277 VAC, with a higher rating of 65 kA at 240 VAC, enabling it to handle fault currents across a range of configurations while minimizing nuisance trips. As part of the Square D family, the EHB34015 is designed for compatibility with Square D panel components and is suitable for installations where 480Y/277 VAC three-phase power is used.
