Eaton ELHFD3040 40A 3-Pole 600 V Circuit Breaker

Eaton ELHFD3040 is a 40A, 3-pole circuit breaker rated for up to 600 V, built to protect three‑phase electrical circuits in demanding commercial and industrial environments. This genuine Eaton device delivers reliable overcurrent protection for motor drives, HVAC systems, conveyors, and other heavy equipment, helping prevent downtime and equipment damage.

The ELHFD3040 part number identifies the exact unit designed to fit Eaton panels and distribution gear that accept ELHFD-series breakers. With a three-pole design, it simplifies wiring in three‑phase layouts and streamlines service and maintenance by using a common trip and mounting footprint across your installation.

• Three-pole, 40-amp rating for precise protection of 3-phase circuits up to 600 V
• Durable construction designed for industrial panels and switchgear
• Direct-fit compatibility with Eaton panels that accept ELHFD breakers
• Clear labeling of rating and part number for fast identification during maintenance
• Ideal as a replacement or standard in new installations for three-phase loads

Use cases include motor control circuits in manufacturing lines, three-phase power distribution for HVAC and pump stations, and safeguarding equipment in packaging and material handling systems. If you’re upgrading an older installation or standardizing parts across multiple panels, the ELHFD3040 provides a reliable, Eaton-specific solution with predictable performance and traceability.

When selecting a breaker, ensure your system supports 600 V three-phase operation and that the panel or switchgear accepts ELHFD-series devices. Keep a stock of ELHFD3040s on hand for quick replacements to minimize downtime and maintain consistent protection across your electrical infrastructure.
