Square D EGB14020U Molded Case Circuit Breaker

The Square D EGB14020U is a 1‑pole, 20‑amp molded‑case circuit breaker from Square D (Schneider Electric) designed for 277 VAC branch circuits in commercial and industrial panelboards. As part of the E‑Frame EGB family, it uses a thermal‑magnetic trip to provide reliable overcurrent protection and short‑circuit interruption, with a bolt‑on mounting arrangement that fits standard Square D panels that support E‑Frame devices. It delivers an interrupting capacity of 35 kA at 277 VAC, enabling fast fault clearance for lighting, receptacle, and small‑motor circuits, and it accepts conductor sizes of 14–6 AWG aluminum or copper for flexible installation. This 1P, 20A MCCB is built to withstand the rigors of commercial environments and is commonly used where 277‑V distribution is required, coordinating with other Square D protection devices in panelboards engineered for E‑Frame breakers. With its designation as a molded‑case breaker in Square D’s lineup, the EGB14020U provides a compact, single‑circuit solution that prioritizes precise protection without sacrificing compatibility with established panelboard architectures.
