Eaton GD3015A3 Circuit Breaker, 15A, 3-Pole, 480V

Engineered by Eaton for industrial electrical service, maintenance, and replacement projects, the GD3015A3 circuit breaker delivers reliable overcurrent protection for three‑phase systems up to 480V. With a 15A rating across three poles, it provides balanced, predictable protection across all phases, helping safeguard equipment, wiring, and personnel in demanding environments.

Key advantages of the Eaton GD3015A3:

• Three-pole configuration for true three‑phase protection in 480V systems, ensuring synchronized interruption across all phases.
• 15 Amp rating tailored to moderate-load circuits that power motors, conveyors, and other industrial equipment.
• Durable design suited for routine maintenance and replacement projects, making swaps quick and straightforward in compatible panels and switchgear.
• Clear part identification with the GD3015A3 part number to verify fit and application requirements—critical for ensuring correct trip characteristics and physical compatibility.
• Versatile for both retrofits in legacy installations and new installations that require a robust, three-pole 480V protective device.

Use cases you’ll appreciate:

• Protecting 3-phase feeders in manufacturing lines powered by 480V, reducing downtime from electrical faults.
• Upgrading older electrical panels that require a 15A, 3-pole breaker to maintain safe, reliable operation.
• Replacing failed breakers during planned maintenance to keep critical equipment running smoothly.

Notes: Verify fit by part number and application requirements. If you’re unsure about compatibility, our team can help confirm that GD3015A3 is the right choice for your specific panel and system configuration.
