Square D FAL340501212 - 50A, 3-Pole, Circuit Breaker

Engineered for dependable protection in three‑phase power systems, the Square D FAL340501212 delivers reliable 50A, 3‑pole circuit breaking for panelboards, switchboards, and control panels. Built for industrial, commercial, and OEM environments, it safeguards motors, drives, and other heavy loads from overcurrent events while simplifying panel design and maintenance.

Why this 3‑pole design matters

• Three‑pole protection provides synchronized disconnect across all three phases, helping to prevent unbalanced faults and reducing the risk of equipment damage in three‑phase systems.
• 50A rating targets mid‑sized circuits, offering solid protection for common motor loads and distributed power feeds without unnecessary nuisance trips.
• Versatile compatibility suited for integration in panelboards, switchboards, and control panels used across industrial facilities, commercial sites, and OEM equipment racks.

Practical benefits in real-world use

• Protects critical equipment in motor control centers (MCCs) and distribution panels, helping to minimize downtime and repair costs from overcurrent events.
• Facilitates safer maintenance by ensuring a reliable, predictable shutdown across all active conductors when tripped.
• Designed to fit into standard three‑phase electrical architectures, making replacement or upgrades straightforward within existing Square D ecosystems.

Ideal applications

• Industrial facilities with three‑phase motors, conveyors, pumps, or large loads
• Commercial sites employing three‑phase power for HVAC, processing equipment, or heavy machinery
• OEM machinery and control cabinets that require robust, easy‑to‑source overcurrent protection

Tips for selection and installation

• Match the breaker to the three‑phase load and ensure the panelboard or switchboard is listed for use with this 3‑pole 50A device.
• Confirm that the installation environment supports the electrical and mechanical specifications of the FAL340501212 for reliable performance.
• Plan for easy future maintenance by keeping spare devices in inventory and labeling circuits clearly to speed up fault isolation.

With the Square D FAL340501212, you get a purpose‑built, three‑phase protection solution that aligns with industrial workflows and MSD (motor‑driven) applications. It’s a focused choice for teams prioritizing dependable overcurrent protection, streamlined maintenance, and compatibility within a robust electrical distribution setup.
