Schneider Electric BDL36040 40A 3-Pole 347 V Circuit Breaker

Meet the Schneider Electric BDL36040 40A 3-Pole 347 V Circuit Breaker—built to guard your three-phase distribution from overloads and short circuits with precise, reliable performance.

Designed for commercial and light industrial environments, this unit's 347V rating aligns with common three-phase voltage levels found in business settings, while its 40-amp current rating protects feeders and equipment without nuisance trips during startup surges.

Key specifications

• Part Number: BDL36040
• Current rating: 40 A
• Poles: 3
• Voltage rating: 347 V

Why this matters

When you run a 3-phase system, coordinated protection across all phases reduces the risk of unbalanced faults and collateral damage. The BDL36040 is engineered to trip the moment your three-phase loads exceed safe limits, helping to keep motors, drives, and circuits safe and downtime minimal.

Ideal use cases

Three-phase feeders in commercial buildings, data centers, HVAC systems, and manufacturing environments where 347V distribution is standard. It integrates smoothly with Schneider Electric panels and components, ensuring compatibility and streamlined maintenance.

Installation and maintenance tips

• Replace like-for-like using the same part number (BDL36040) to preserve ratings and protection coverage.
• Verify panel compatibility and follow manufacturer torque specifications during installation.
• Regularly inspect for signs of wear or tripping history to anticipate maintenance needs.
