Square D | FHP26045 | Circuit Breaker | 45A | 2-Pole | 600V

The Square D FHP26045 circuit breaker is a purpose-built protective device designed to deliver dependable overcurrent protection in demanding electrical systems. With a 45-amp rating across two poles and a 600-volt maximum, this unit is engineered for reliable performance in panels that require precise compatibility and robust protection.

Key specifications

• Amperage: 45 A
• Poles: 2-Pole
• Voltage rating: 600 V
• Part number: FHP26045

Why this specific part matters: using the exact part number ensures the breaker matches the panel’s design, trip curves, and mounting footprint. The FHP26045 designation is the most reliable reference for compatibility, helping you avoid fitment issues during maintenance or retrofits.

Ideal use cases

• Maintenance on Square D panels that require a precise 45A, 2-pole, 600V protective device
• Retrofits where existing protection needs to be upgraded or replaced with an exact spec match
• Replacement in legacy installations where matching the original part number minimizes wiring and fitment concerns

What sets it apart

This breaker is not a generic substitute. By aligning to the FHP26045 specification, you ensure proper fitment, electrical performance, and safety alignment with your Square D system. The two-pole design supports protection across two conductors, which is essential for circuits operating at higher voltages or requiring simultaneous disconnection of multiple conductors.

Installation and compatibility notes

Before ordering, verify that the panel labeling references the FHP26045 family and that the ratings align with the circuit you’re protecting. The part number is the best reference for compatibility, so cross-check it against your panel catalog and any service documentation. For best results, handle the breaker with appropriate PPE, de-energize the panel before work, and follow all local electrical codes during replacement or retrofit.
