Square D | FA36050-BLACK | Circuit Breaker | 50A | 3-Pole | 600V

Meet the Square D FA36050-BLACK circuit breaker—a 50A, 3-pole unit designed to protect three-phase circuits operating up to 600V. Built for maintenance, retrofit, and replacement work, this breaker helps you restore reliable protection quickly while preserving panel consistency.

• Amperage: 50A
• Poles: 3-Pole
• Voltage rating: 600V
• Part reference: FA36050-BLACK
• Usage: maintenance, retrofit, and replacement to restore protected circuits
• Important: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Why this matters in real-world installations: a 3-pole design ensures synchronized disconnection across all hot legs in a three-phase system, reducing risk of phase imbalance and equipment damage during faults. The 50A rating targets feeders and motors that require stronger protection than a single-pole device, while the 600V rating supports higher-voltage applications common in industrial settings.

Ideal use scenarios include upgrading legacy electrical panels in manufacturing lines, replacing failed protection in critical processing equipment, or retrofitting to meet updated electrical codes while minimizing downtime. This variant is the exact FA36050-BLACK reference you need to match your existing Square D installation.

Practical tips for a smooth fit and reliable performance:

• Verify that your panel accepts FA-series breakers and supports a 50A, 600V rating.
• Use the FA36050-BLACK as the exact part reference when ordering to ensure compatibility.
• Prepare the electrical environment: de-energize the system, discharge residuals, and inspect bus connections for clean contact.
• Have a licensed electrician perform installation to ensure proper torque and safe operation.
