EH3030 | Circuit Breaker | 30A | 3-Pole | 480V

The EH3030 is a rugged industrial circuit breaker engineered for demanding 480V three-phase environments. With a 30A rating and a 3-pole configuration, it delivers coordinated protection across all phases, helping you safeguard motors, drives, and distribution feeders from overloads and short circuits during maintenance, retrofit, or replacement projects.

Key specifications

• Amperage: 30 A
• Poles: 3-Pole
• Voltage: 480 V

For exact fit and ongoing reliability, the part number EH3030 is the most reliable reference. Always confirm fit and ratings before ordering to ensure seamless replacement in your panel or drive system.

Why this breaker stands out

Unlike generic substitutes, EH3030 is a purpose-built match for 480V, three-phase systems. The 3-pole design ensures simultaneous disconnection of all phases, reducing the risk of arc faults and unbalanced loads. This translates to cleaner trips, quicker fault isolation, and less downtime during critical maintenance windows.

Ideal applications

• Maintenance, retrofit, and replacement in industrial electrical panels and feeders
• Protection for 480V three-phase motors, drives, and powered equipment in manufacturing and processing facilities
• Spare or standby breaker for service teams handling 480V distribution networks
• Upgrading legacy installations to a coordinated three-pole protection scheme

Installation and compatibility tips

• Use the EH3030 part number to verify compatibility with your panel family and existing wiring scheme.
• Confirm that the installation is dedicated to 480V three-phase circuits and that the enclosure is rated for this voltage and configuration.
• Before installation, ensure power is fully shut off, conductors are within allowed torque specifications, and termination hardware matches the breaker’s design.
• Label the new breaker clearly in the panel schedule to reflect its 30A, 3-Pole, 480V rating for future maintenance checks.
