Square D | FHL26070 | Circuit Breaker | 70A | 2-Pole | 600V

Meet the Square D FHL26070 Circuit Breaker — a purpose-built protection device for demanding electrical systems. With a 70-amp rating, this 2-pole breaker is designed to interrupt power efficiently on 600-volt circuits, delivering reliable overcurrent protection for high-load applications in both residential and commercial settings.

Key specifications

• Amperage: 70 A
• Poles: 2-Pole
• Voltage rating: 600 V

Why this model matters

• Genuine Square D construction ensures exact fit, predictable trip characteristics, and seamless compatibility with compatible Square D panels and enclosures.
• Designed for maintenance, retrofit, and replacement projects where you need a reliable, factory-listed part that you can trust to protect wiring and devices downstream.
• Compact, plug-in installation footprint minimizes panel downtime and simplifies swaps in existing electrical panels.

Use cases and ideal scenarios

• Feeding high-demand appliances or circuits in commercial spaces, such as large water heaters, HVAC equipment, or subpanel feeders.
• Retrofits where an existing 70 A, 2-pole, 600 V breaker matches the panel labeling and listing.
• Panel upgrades or serviceability work that require a like-for-like replacement to maintain UL listing and warranty integrity.

Important compatibility note

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility with your specific panel lineup, so match FHL26070 to the enclosure and bus bar arrangement currently installed in your electrical system.

Practical tips for a smooth install

• Power down the main breaker and verify zero voltage on the circuit before removing the old breaker.
• Use the correct torque when tightening lugs as specified by the panel manufacturer (refer to the panel’s installation guide).
• Handle the breaker by its body, avoid lever force that can bend mounting clips.
• Keep a spare high-amperage breaker for timely maintenance without panel downtime.
