EGB34050

The Square D EGB34050 is a ‑pole,  amp bolt‑on molded‑case circuit breaker designed for reliable overcurrent protection in three‑phase electrical distribution systems. It belongs to the EGB series of breakers from Square D by Schneider Electric, tailored for use in NF panelboards and other commercial/industrial switchgear requiring robust branch‑circuit protection. The bolt‑on mounting style ensures a secure mechanical connection to the panelboard bus, making this device suitable for retrofit and new installations where dependable three‑phase protection is needed.

Electrically, the EGB34050 is rated for  amps continuous current at 480Y/277 VAC and utilizes a thermal‑magnetic trip unit that combines long‑time overload protection with magnetic instantaneous response to short‑circuit events. It carries a typical {aic rating} interrupting rating, allowing it to safely interrupt fault currents in commercial environments. The breaker is also HACR‑rated (Heating, Air Conditioning, and Refrigeration) and HID‑rated for heavy lighting loads, with a built‑in trip indicator to aid in troubleshooting.

Mechanically, the EGB34050 features a compact molded case with lug connections for copper or aluminum conductors (AWG 14–6 for copper and AWG 12–6 for aluminum), and is calibrated for operation at 40 °C. It supports branch‑circuit applications such as feeder protection, motor control disconnects, lighting panels, and other three‑phase loads where reliable protective coordination with upstream devices is critical. Square D’s long heritage in circuit protection — now part of Schneider Electric, a global leader in energy management and automation — ensures continued availability and compliance with modern safety standards.
