Square D FAL-36003-11M Circuit Breaker, 3A, 3-Pole, 600V

When you need dependable overcurrent protection in demanding industrial environments, the Square D FAL-36003-11M Circuit Breaker delivers precise control for three-phase systems. Built for service, maintenance, and replacement projects, this 3A, 3-pole unit is designed to handle up to 600V, making it ideal for protecting motors, feeders, and control circuits in factories and commercial facilities.

• Three-pole protection supports balanced three-phase circuits, ensuring simultaneous interruption across all phases for coordinated protection.
• 3 ampere rating provides appropriate protection for small-to-moderate loads and sensitive equipment, preventing nuisance trips while safeguarding wiring and components.
• 600V max rating suitable for common industrial distribution and control panels that operate at higher voltages.
• Part of the Case Breaker FAL family, a trusted Square D solution known for robust performance in industrial panelboards and control panels.
• Compatibility verification—verify fit by part number FAL-36003-11M and ensure it matches your application requirements. Need help matching a part number or confirming compatibility? Message us and we'll help.

Use cases and scenarios:

- Replacing a failed breaker in legacy Square D installations with minimal downtime by selecting the exact same part number (FAL-36003-11M) to preserve panel configuration and trip characteristics.

- Installing in new or existing 3-phase panels where 600V operation is standard, such as motor feeders, conveyor drives, or control power circuits in manufacturing lines.

Why this matters:

Choosing the right 3A, 3-pole breaker with a 600V rating ensures devices stay protected without over-tripping. The FAL-36003-11M’s 3-pole design coordinates shutdown across all three phases during a fault, reducing arc energy and equipment stress while helping maintain electrical safety and uptime.

Practical tips:

• Keep a small library of common Square D FAL part numbers for quick replacements in maintenance programs.
• Confirm in-panel compatibility by cross-checking the exact part number against your schematic and component list—even within the same family, trips and wiring configurations may differ.
• When in doubt, reach out with your application details (voltage, load type, breakers already in service) to ensure seamless substitution.
