Meet the Industrial QC3055H 55A 3-Pole 240 V Circuit Breaker — a compact, heavy-hitting solution for three-phase electrical protection in demanding settings. Part Number QC3055H ensures you have the exact replacement or upgrade you need in your panel.

Key specifications

  • Current rating: 55 A
  • Poles: 3 (suitable for three-phase circuits)
  • Voltage rating: 240 V
  • Application: industrial circuits and machines requiring reliable overcurrent protection

Why this 3-Pole 240 V breaker matters

In industrial environments, protecting equipment from overloads and short circuits is non-negotiable. The QC3055H provides robust overcurrent protection for three-phase loads, ensuring that all three conductors trip together. This coordinated response minimizes phase-to-phase faults and reduces the risk of motor or drive damage, helping you avoid expensive downtime and repairs.

Ideal use cases

  • Three-phase motors and conveyors in manufacturing lines
  • Industrial HVAC equipment and chillers with 3-phase power
  • Power distribution panels in warehouses, plants, and workshops
  • Machine tools and processing equipment fed from 240 V three-phase supplies

Benefits and practical considerations

With the QC3055H, you get consistent, predictable protection for loads up to 55 A across 3-phase circuits. This helps you:

  • Prevent equipment damage from overloads
  • Contain electrical faults quickly, limiting arc flash risk and fire potential
  • Maintain safe, stable operation of your industrial line by avoiding partial-phase energization

Installation notes (high level): ensure the circuit breaker is compatible with your panel’s bus and mounting style, confirm that the terminal sizes and wiring method match your conductors, and follow all applicable electrical codes and safety guidelines during replacement or installation. Use Part Number QC3055H to confirm compatibility with your existing panels and spares inventory.

Order the QC3055H today to strengthen your electrical protection and keep your operations running smoothly.
