Square D FA36080 - 80 A, 600 V, 3-Pole Plug-In Circuit Breaker | AmpState

Meet the Square D FA36080: an 80 A, 600 V, 3-pole plug-in molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short‑circuit protection in panelboards and load centers. Built for quick swaps and reliable performance, it’s the smart choice for securing critical electrical distribution in practical, real‑world settings.

Key Benefits

• Fast plug-in installation: The quick-connect design makes installation and replacement straightforward, reducing downtime during upgrades or servicing.
• Thermal‑magnetic trip unit: Combines precise thermal protection with instantaneous magnetic response for stable, repeatable protection across a range of fault conditions.
• 3-pole, 80A, 600V rating: Ideal for three-phase distribution scenarios common in commercial and light industrial environments, while handling robust loads safely.
• OEM compatibility: Engineered to work with matching Square D OEM load centers and panelboards, ensuring coordinated protection and a seamless fit.
• Versatile applicability: Specifically suited for residential, commercial, and light industrial applications requiring reliable branch circuit protection and short‑circuit defense.

Technical Snapshot

• Manufacturer: Square D
• Part Number: FA36080
• Type: Thermal-magnetic molded case circuit breaker
• Amperage Rating: 80 A
• Voltage Rating: 600 V
• Number of Poles: 3
• Mounting Style: Plug-in
• Application: Branch circuit overcurrent and short-circuit protection

Use Cases and Scenarios

Use the FA36080 in panelboards and load centers where three-phase distribution is required and reliable protection is non-negotiable. It’s well-suited for: office buildings with centralized power distribution, small manufacturing spaces with mixed equipment loads, and commercial environments where quick maintenance and minimal downtime are priorities. When an aging breaker needs replacement, the plug-in design lets technicians swap it in minutes without disrupting adjacent circuits.

Why This Breaker Stands Out

Beyond basic protection, the FA36080 offers a thoughtful combination of features that matter in real-world installations. The plug-in connection isn’t just about speed—it minimizes the risk of loose connections that can cause nuisance trips. The thermal-magnetic trip mechanism provides a balance between preventing overheating damage and avoiding unnecessary interruptions, helping protect wiring, devices, and downstream equipment without compromising performance.

Installation & Safety Recommendations

• Verify that your panelboard is compatible with 3-pole plug-in breakers and rated for 600 V.
• Consult the OEM installation guidelines for proper mounting and alignment to maintain uninterrupted protection.
• Plan for regular inspection and testing as part of a proactive electrical maintenance routine to ensure the trip unit remains within specification.

Enhance your electrical distribution with the Square D FA36080—trusted protection, fast maintenance, and seamless compatibility for reliable, long‑term performance.
