Industrial GI3125 25A 3-Pole 480 V Circuit Breaker

Engineered for demanding industrial power distribution, the GI3125 Industrial Circuit Breaker delivers dependable protection for three‑phase systems. With a 25 A current rating and a 3‑pole design, this device is purpose-built to guard equipment and wiring in 480 V networks. Part Number GI3125 is your signal that you’re choosing a rugged, purpose‑built solution for continuous operation in harsh environments.

• Three-pole protection—perfect for guarding 3‑phase motors, pumps, conveyors, and CNC machinery powered from 480 V. By disconnecting all three phases, it minimizes the risk of latent faults and uneven loading across phases.
• Precise 25 A rating—calibrated to protect branch circuits from overloads while allowing normal startup and operation of connected equipment.
• Industrial-grade reliability—designed to withstand the demands of manufacturing floors, process plants, and other heavy-duty settings where uptime matters.
• Compact, panel-ready form—built to fit standard electrical enclosures and distribution boards, making it a practical upgrade or replacement in existing systems.

Ideal applications and use cases

• Wiring 3‑phase equipment in industrial panels, motor control centers, and distribution boards that run on 480 V.
• OEMs integrating robust overcurrent protection into new machines or packaging lines.
• Electrical contractors and panel builders needing a reliable, standard 3‑pole solution for high‑voltage environments.

What sets GI3125 apart

Beyond basic specs, this circuit breaker targets real-world needs: complete three‑phase disconnection to prevent residual fault paths, and a solid 25 A rating that aligns with common industrial loads while keeping nuisance tripping to a minimum. In environments where space matters, its three‑pole configuration delivers efficient protection without compromising enclosure space, helping you streamline wiring and maintenance.

Practical considerations for installation and use

• Verify that your panel or distribution board is rated for 480 V and supports a 3‑pole device.
• Match the GI3125 to the protected load’s current profile to ensure reliable tripping without unnecessary interruptions.
• Follow standard electrical safety practices during installation, and refer to your system documentation for wiring and torque guidelines.

Choose the GI3125 25A 3‑Pole 480 V Circuit Breaker for robust, reliable protection of three‑phase equipment in demanding industrial environments. Its purpose‑built design helps protect valuable assets, reduce downtime, and simplify panel design in 480 V power systems.
