• Poles: 3-Pole
• Voltage: 240V
• Compatibility reference: Part number P4340 is the best reference for matching fit

Why the P4340 matters in your electrical panel

Designed for real-world panel work, this breaker delivers dependable protection across all three phases of a 240V system. Its three-pole configuration ensures coordinated circuit shutdown on trip, reducing the risk of unbalanced currents that can stress equipment and wiring. When you need a like-for-like replacement or a retrofit that preserves your existing electrical topology, the P4340 provides a precise match to your specifications.

Who this is for and practical use cases

• Facilities teams performing panel maintenance or upgrades in commercial or light industrial settings.
• Electricians conducting retrofits or replacements where one-to-one spec matching is critical.
• Maintenance workflows that require a ready-to-install 40A, 3-pole, 240V protective device to minimize downtime.

Key considerations to ensure a smooth fit

• Always confirm compatibility by cross-referencing the part number (P4340) with your panel labeling and documentation before ordering.
• Verify that your system voltage is 240V and that a 3-pole arrangement aligns with your three-phase circuit layout.
• Follow standard electrical safety practices and local codes during installation and maintenance.
