Square D EGB26015 - 15 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Square D EGB26015 — a 15A, 480V, 2-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and loadcenters. Built for residential, commercial, and light industrial environments, this device provides precise overcurrent and short-circuit protection with a focus on long-term reliability and ease of maintenance.

• Bolt-on mounting: secure, rigid bus connections that resist vibration and movement, ensuring consistent performance in panels subject to environmental or mechanical stresses.
• Thermal-magnetic trip unit: combines stable thermal protection with fast magnetic actuation for immediate response to short circuits, delivering repeatable protection across temperature variations.
• 2-pole, 480V rating: designed to simultaneously disconnect both conductors on higher-voltage circuits, enhancing safety and reducing fault paths in 2-phase or three-phase systems.
• OEM-compatible: engineered to be a drop-in fit with matching Square D OEM load centers and panelboards, simplifying replacement, stock management, and field service.
• Versatile application: ideal for protecting branch circuits in residential feeders, commercial distribution panels, and light industrial panelboards where reliable 2-pole protection is needed.

Why this matters for your project

When selecting protection for higher-voltage panels, reliability and compatibility matter as much as the electrical rating. The EGB26015 combines a proven Square D design with a robust bolt-on mount and a dual-mode trip system, delivering predictable trip characteristics and a solid, vibration-resistant connection. This means fewer nuisance trips, easier maintenance, and confident protection for critical loads.
