Schneider Electric's Square D EDB14020LH is a 1-pole E-Frame miniature circuit breaker rated for 20 A at 277 VAC, designed for bolt-on (chassis) mounting in compatible panels. It uses a thermal-magnetic trip mechanism with a 25 kA maximum interrupting rating and features a lever-style actuator for manual operation. This TAA-compliant device is built for commercial and industrial panelboards that accept E-Frame breakers, with high-amp lug compatibility for secure terminations. It protects a single hot leg in 277 V circuits, providing reliable overcurrent protection for branch circuits in distribution enclosures.
