Schneider Electric EGB34100 Bolt On Circuit Breaker

Schneider Electric's Square D EGB34100 is a 3-pole, 100 A bolt-on molded‑case circuit breaker from the EGB (E‑Frame) family, rated for 480Y/277 VAC three‑phase service. It uses bolt‑on mounting for secure, in‑panel installation and carries an interrupting rating up to 65 kA at 480Y/277 VAC, suitable for circuits with high fault currents. This 100 A device provides thermal‑magnetic protection with long‑time and instantaneous trip functions, designed for industrial and commercial distribution panels that require a bolted connection rather than a plug‑in breaker. Compatible with Square D EGB equipment and standard bolted‑on panelboard configurations, it delivers reliable overcurrent protection in 3‑phase power systems.
