Schneider Electric EGB24125 Molded Case Circuit Breaker

Schneider Electric’s Square D EGB24125 molded‑case circuit breaker is a 2‑pole device rated for 125 amps, built for 480Y/277 VAC service in Square D NF panelboards. As part of the E‑Frame family, this bolt‑on mount MCCB uses aluminum lug terminals for straightforward field wiring and incorporates a thermal‑magnetic trip mechanism to provide reliable overcurrent protection. The EGB24125 is designed for commercial and light‑industrial distribution, protecting feeders and branch circuits feeding electrical panels and equipment across three‑phase power systems. Its compact E‑frame construction fits standard enclosures, offering a drop‑in replacement option in existing Square D NF panelboard installations, while delivering solid protection for circuits up to 125 A at 480Y/277 VAC. Typical applications include service feeders in data centers, office complexes, manufacturing facilities, and other buildings requiring dependable overcurrent protection for 480Y/277 VAC distribution networks. The device emphasizes durable insulation and robust mounting suitable for panelboard environments, making it a common choice when upgrading or replacing aging MCCBs in existing Square D installations.
