Installation and compatibility tips

Notes to ensure a successful match: Confirm fit and ratings before ordering. The part number is the best reference for compatibility with your panel or enclosure. If you’re replacing an existing unit, verify that the panel is intended for a 600V, two-pole bolt-on breaker and that the mounting footprint aligns with the existing hardware.

Practical considerations for field installation include arranging the appropriate protective PPE, de-energizing the circuit before work, and following your facility’s lockout/tagout procedures. Keep a spare FAP26100 on hand for future maintenance needs to minimize downtime.

With its proven Square D engineering, the FAP26100 100A 2-Pole 600V bolt-on circuit breaker provides durable overcurrent protection, streamlined retrofitting, and dependable performance in demanding electrical systems. If your project requires a precise, compatible replacement that aligns with legacy gear and modern safety standards, this is a reliable choice for safeguarding your electrical network.
