Square D EGB34035 - 35 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Discover the Square D EGB34035—a 35A, 480V, 3-pole bolt-on molded‑case circuit breaker designed for dependable branch circuit protection in panelboards and loadcenters. Manufactured by Square D and available from AmpState, this unit delivers reliable overcurrent and short‑circuit protection for commercial, light industrial, and residential settings where stable performance matters in demanding environments.

Why this breaker stands out

• Secure bolt-on mounting ensures a rigid, vibration‑resistant bus connection, reducing the risk of loose contacts that can lead to intermittent trips or electrical noise in panels subject to vibration.
• Thermal‑magnetic trip unit delivers stable, repeatable protection by responding precisely to overloads and short circuits, helping prevent damage to feeders, motors, and downstream equipment.
• OEM‑aligned compatibility works with matching Square D loadcenters and panelboards, offering a straightforward, plug‑and‑play upgrade or replacement path without custom adaptations.
• Three‑pole configuration for 3‑phase systems and a 480V rating, making it ideal for commercial lighting, HVAC controls, machinery feeds, and other 3‑phase distribution needs.
• 45‑ampere protection logic in a compact form provides targeted protection for branch circuits that require a precise 35A trip threshold while fitting within standard panel enclosures.
