Schneider Electric EGB34050 Molded Case Circuit Breaker

Schneider Electric EGB34050 is an E-Frame molded‑case circuit breaker rated for 50 A in a 3‑pole configuration for 480Y/277 VAC systems. This bolt‑on device delivers thermal‑magnetic protection with an interrupting capacity up to 65 kA at the 480Y/277 VAC rating, making it suitable for safeguarding 3‑phase feeders in commercial and industrial electrical distribution panels. As part of the Square D/E‑Frame family, the EGB34050 is designed for panelboard and equipment installations that require a robust, bolted connection MCCB with a 50 A rating and TAA compliance. The unit is intended to interrupt and isolate a 3‑phase circuit under overload or short‑circuit conditions, helping protect downstream wiring and equipment, while providing balanced protection across all three phases. The 480Y/277 VAC class voltage rating aligns with common commercial power distribution standards, and its bolt‑on mounting supports straightforward integration within compatible enclosures and panels.
