HEG431040 | Circuit Breaker | 40A | 3-Pole | 480V

Meet HEG431040, a purpose-built industrial circuit breaker designed to protect demanding three‑phase power systems. With a 40A rating, a 3‑pole configuration, and a 480V operating capability, this unit delivers sturdy, reliable interruption in environments where uptime matters and safety cannot be compromised.

Designed for maintenance, retrofit, and replacement projects, HEG431040 is the precise fit when your system requires exact specifications. Rely on the part number itself—HEG431040—as the strongest reference for compatibility, reducing guesswork and ordering errors in critical panel upgrades.

• Exact specifications at a glance: 40A amperage, 3‑pole configuration, 480V three‑phase rating
• Precise fit for replacements and retrofits: Use the HEG431040 part number to verify compatibility with existing panels and enclosures
• Industrial-grade protection: Built to guard electrical circuits in demanding environments, helping minimize unplanned outages
• Streamlined maintenance pathways: A reliable, standardized component that simplifies stocking and service intervals

Ideal for professionals and facilities teams responsible for three‑phase networks in manufacturing floors, data centers, process facilities, or large HVAC and pumping systems. If your distribution setup runs on 480V three‑phase power and you need a robust 40A protective device within a three‑pole footprint, this breaker is engineered to meet that need.

Use cases and practical scenarios:

• Retrofits in legacy panels where new equipment must match existing 3‑phase protection without redesigning the busbar layout
• Maintenance replacements to restore reliable overcurrent protection after component wear or tripping events
• New installations in industrial environments that operate at 480V three‑phase power, ensuring consistent protection across all three phases
• Panel upgrades in data centers, manufacturing lines, and process facilities where a precise 40A, 3‑pole, 480V spec is required

Important note: Confirm fit and ratings before ordering. The part number HEG431040 is the best reference for compatibility to ensure a seamless integration into your system.
