Square D | PHF2536-700A | Circuit Breaker | 700A | 3-Pole | 600V | Bolt-On

Engineered for serious industrial applications, the Square D PHF2536-700A Circuit Breaker delivers robust protection for high‑current, three‑phase systems. This 700A, 3‑pole, 600V bolt‑on device is designed for reliability and ease of service in retrofit, maintenance, and replacement projects where exact specifications matter.

Precise, purpose‑built protection

• 700A amperage rating guards power feeders and motor circuits against overloads without nuisance tripping in normal operation.
• 3‑pole configuration suits 3‑phase systems, providing balanced protection across all phases.
• 600V voltage rating supports common industrial distributions while maintaining safe insulation and interrupting capability.
• Bolt‑on mounting offers solid, field‑aligned installation with secure bus connection—ideal for panels designed to accept bolt‑in devices.
• PHF2536‑700A part reference ensures compatibility with Square D bolt‑on frames and the PHF series specification in your panel catalog.

Where and how you’ll use it

Ideal for maintenance, retrofit, and replacement projects where a high‑capacity, reliable breaker is required. Use this device in switchgear or control panels that demand a bolt‑on, three‑pole, 600V protection solution. It’s a practical choice for data centers, manufacturing lines, and large equipment rooms where uptime matters and downtime costs add up.

Key benefits that matter in the real world

• “Drop‑in” compatibility with existing PHF bolt‑on frames reduces installation complexity and downtime during upgrades.
• Heavy‑duty construction stands up to demanding environments, helping prevent nuisance trips while protecting downstream equipment.
• Precise trip characteristics and a clearly identifiable part number simplify ordering, inventory, and service planning.

Installation and compatibility tips

Before ordering, verify fit and ratings against your panel’s catalog. Confirm that the enclosure supports PHF bolt‑on breakers and that the bus alignment matches your three‑phase distribution layout. When installing, follow panel manufacturer torque specs and ensure all mounting bolts are properly secured to maintain reliable electrical contact under load. Keep the PHF2536‑700A clean and dry prior to installation to preserve performance.

Why choose this Square D breaker over other options?

This PHF2536‑700A is purpose‑built for high‑current, three‑phase protection with a bolt‑on mount—combining robust mechanical strength with straightforward maintenance. Its design minimizes downtime during upgrades, reduces the risk of mis‑rating by sticking to a single, verifiable part number, and aligns with typical industrial control panel architectures where space and serviceability matter as much as amperage rating.

Ready to upgrade your power protection? Use the Square D PHF2536‑700A for dependable, field‑programmable performance in demanding environments. Confirm fit with your panel’s specifications and place your order with confidence.
