Schneider Electric | FJA34040 | Circuit Breaker | 40A | 3-Pole | 480V

Schneider Electric FJA34040 is a 40A, 3-Pole circuit breaker designed for 480V electrical systems. Built for reliability in demanding industrial environments, this unit is ideal for maintenance, retrofit, and replacement projects where exact specifications matter.

• Amperage: 40 A
• Poles: 3-Pole
• Voltage: 480V
• Reference: Part number FJA34040 is the strongest compatibility indicator

Why choose a three-pole, 480V breaker like this one? In multi-phase distributions, a 3-Pole breaker ensures synchronized protection across all phases, preventing unbalanced loads and protecting equipment from fault conditions. The Schneider Electric design behind FJA34040 is built to integrate smoothly with compatible panels and legacy electrical infrastructure that rely on exact part matching.

Ideal use cases:

• Maintenance and service where you need to replace a worn breaker without changing panel hardware
• Retrofit projects upgrading or converting circuits to a 3-pole, 480V configuration in manufacturing or facility distribution systems
• Replacement for existing installations that specify FJA34040 as the preferred or required part number

Buying guidance: Before ordering, confirm fit and ratings on your panel or enclosure. The part number FJA34040 is the best reference for compatibility with Schneider Electric systems and accessories.

Installation and safety tips:

• Ensure power is fully isolated and de-energized before handling or replacing the breaker
• Use appropriate tools and follow your facility's lockout/tagout procedures
• Verify that the bus, terminals, and mounting configuration on your panel match a 3-Pole 480V device and that the termination method is compatible with the FJA34040 design
• Tighten terminations to the panel's torque specifications and perform a visual inspection after installation
