Square D by Schneider Electric EJB14025 Circuit Breaker

The Square D by Schneider Electric EJB14025 is a 1-pole miniature circuit breaker rated for 25 A at 277 VAC, part of the EJB family (E-frame) with bolt-on mounting for Square D panelboard installations. It uses a thermal-magnetic trip for overcurrent protection and carries an industrial interrupt rating of up to 100 kA at 240 VAC and 65 kA at 480Y/277 VAC, making it suitable for commercial or light industrial applications where rapid fault isolation is required. The breaker accepts lug terminations for 12–6 AWG aluminum or 14–6 AWG copper conductors, with dimensions of roughly 4.05 in long by 0.98 in wide by 5.66 in high, and a 40°C ambient rating. This bolted-on, one-pole unit is designed for use in Square D E-frame installations and provides reliable, code-compliant protection for branch circuits at 277 VAC.
