Square D KH26250AC 26250A 2-Pole 600 V Circuit Breaker

Discover dependable protection for your 600 V electrical systems with the Square D KH26250AC 2-Pole 600 V Circuit Breaker. Designed to deliver precise overcurrent protection, this part — KH26250AC — targets two-pole circuits, ensuring both hot legs trip together for safer, more reliable shutdowns when faults occur. With a current rating of 26250 A, and a 2-pole configuration, it’s built to stand up to demanding industrial and commercial panel environments.

Why this matters

In facilities where uptime matters, every fault can mean costly downtime. The KH26250AC provides coordinated protection for 600 V distribution networks, helping prevent damage to sensitive equipment and reducing arc exposure by reliably disconnecting both conductors during a fault. Its compatibility with Square D panel systems offers predictable performance and streamlined maintenance.

Key features

• Two-pole protection: Simultaneous interruption of both hot legs on 600 V circuits for safer fault clearance.
• 600 V rating: Suitable for industrial and commercial installations that operate at higher voltages.
• Part number clarity: KH26250AC designation aligns with KH family catalogs for easy ordering and cross-referencing.
• Rugged, reliable design: Built to endure the demands of panel installations and ongoing electrical service.

Use cases and ideal applications

Ideal for service panels, feeders, and motor control circuits in manufacturing facilities, data centers, and large commercial buildings where 600 V distributions are common. This 2-pole breaker protects multi-conductor circuits, helping safeguard both equipment and personnel.

How it compares to alternatives

By delivering coordinated two-pole shutoff, this breaker reduces arc exposure and ensures consistent protection across paired conductors—an advantage over single-pole devices in multi-wire circuits. Its compatibility with Square D systems means you’ll experience predictable trip performance and straightforward integration within existing enclosures.

Installation and care tips

• Confirm panel compatibility with KH-series breakers and ensure mounting style matches your enclosure requirements.
• Use with 600 V-rated circuits and select conductors sized according to your panel’s specifications and local codes.
• Regularly inspect panel areas for signs of overheating or wear, and replace components per your maintenance plan or after any fault event.
