Industrial FCL3040 40A 3-Pole 480 V Circuit Breaker

Industrial-grade protection for demanding power distribution, the FCL3040 40A 3-Pole 480 V Circuit Breaker is designed to safeguard three-phase systems in modern facilities. With a 40-amp rating and a 480-volt operating capacity, this part provides reliable interruption when overloads or faults occur, helping keep motors, feeders, and critical equipment protected and your operations running smoothly.

What makes the FCL3040 stand out

• Three-pole design for balanced protection — simultaneous disconnection of all three phases minimizes the risk of unbalanced faults and protects equipment more effectively than single- or two-pole solutions.
• 40 A current rating — precisely sized to protect medium-load circuits and motors without nuisance tripping, supporting steady, reliable operation in industrial environments.
• 480 V voltage rating — tailored for common three-phase industrial distributions, enabling straightforward integration into standard plant electrical systems.
• Part Number FCL3040 — a clear, replaceable component for easy maintenance and spare-part planning in existing installations.

Ideal applications and use cases

• Protection for three-phase motors in manufacturing lines, conveyors, and machine tools
• Feeder protection in industrial distribution panels and MCCs (motor control centers)
• Distribution of heavy-duty loads such as pumps, compressors, and HVAC systems operating on 480 V
• Panel upgrades or replacements where a 3-pole, 480 V solution is required

How it protects your operation

By interrupting current flow during overloads or faults, the FCL3040 helps prevent insulation damage, overheating, and catastrophic equipment failures. Its 3-pole configuration ensures all phases are shut down together, reducing the risk of phase imbalance and electrical hazards. This leads to shorter downtime, safer maintenance windows, and longer equipment lifespans in facilities that rely on robust 480 V three-phase power.

Installation, compatibility, and maintenance tips

• Designed for integration into standard 3-phase, 480 V industrial power architectures. Verify your panel’s rating to ensure compatibility with the FCL3040.
• Use as a direct replacement part when you encounter overload or short-circuit events in 3-phase circuits requiring 40 A protection.
• Schedule regular functional checks per your facility’s maintenance plan to confirm reliable tripping and reset behavior after faults.
