Schneider Electric EGB14020LH Circuit Breaker

Schneider Electric's Square D EGB14020LH is a 1-pole, 20‑amp miniature circuit breaker in the E‑Frame family, designed for bolt‑on mounting in NF panelboards and rated for 277 VAC circuits. It provides thermal‑magnetic overcurrent protection with a 65 kA maximum interrupting rating, enabling it to interrupt fault currents within appropriate panelboard configurations. The LH suffix identifies this particular variant of the EGB14020 device, and Schneider Electric lists it as TAA‑compliant. As part of the Square D line, the EGB14020LH is intended for use in commercial and light‑industrial environments where 277 VAC is standard and EF‑frame panelboards accept bolt‑on breakers. When installed in compatible EF‑frame panelboards or enclosures, this 1P, 20 A breaker protects single‑phase circuits, delivering reliable protection against overloads and short circuits in 277 VAC distribution systems.
