Square D EGB34050SA N Molded Case Circuit Breaker

The Square D EGB34050SA N is a three‑pole molded‑case circuit breaker in the Square D EGB family, rated for 50 A in 480Y/277 VAC three‑phase systems and designed for bolt‑on installation in commercial and industrial power‑distribution panels. The SA suffix denotes a shunt‑trip configured variant, enabling remote trip control, while the N designation remains part of the model notation for this bolt‑on MCCB. This device is thermal‑magnetic, providing reliable overload protection with interrupting capacities cataloged for 480 V configurations ranging roughly from 35 kAIC to 65 kAIC depending on the exact variant, so the precise rating for this exact part should be confirmed in the official data sheet. Built for industrial use, it features robust E‑Frame construction and is suitable for protecting feeders and power circuits in distribution boards with a 480Y/277 VAC three‑phase supply.
