Key specifications at a glance

• Amperage: 15A
• Poles: 3‑Pole
• Voltage: 480V
• Part number: GDB3015D (best reference for compatibility)

Why this GDB3015D matters for your system

In a three‑phase setup, coordinated tripping across all three conductors is essential to prevent single‑phase faults that can damage motors, drives, and control circuits. The GDB3015D provides that balanced protection, helping to:

• Protect costly equipment in manufacturing lines, HVAC installations, and motor control centers
• Minimize downtime by reliably interrupting fault currents at the source
• Simplify maintenance planning with a dedicated, recognizable part number for exact replacements

Ideal applications and use cases

• Retrofits in legacy panels where 480V three‑phase protection is required
• Maintenance spares for ongoing plant reliability
• Replacement parts in new or rebuilt control panels that demand a 15A, 3‑pole, 480V solution
• Motor control centers, distribution boards, and industrial switchgear that rely on coordinated phase protection

Installation and compatibility tips

• Always confirm fit and ratings before ordering—match the GDB3015D part number to ensure correct trip characteristics, mounting, and enclosure compatibility
• Verify that your system is indeed a 480V three‑phase configuration and that a 15A rating aligns with your protected circuit
• Use this device as a precise replacement for similar 3‑pole breakers in compatible panels to maintain protective coordination

With its clear, purpose‑driven design, the GDB3015D stands out as a thoughtful, purpose-built solution for industrial protection needs. When you’re maintaining or upgrading three‑phase systems at 480V, this 15A, 3‑pole circuit breaker delivers dependable performance and easy traceability through its dedicated part number. Add it to your cart to ensure consistent protection for your critical equipment and streamline future replacements.
