Eaton QC3080HT 80A 3-Pole 240 V Circuit Breaker

When your project runs on three-phase power, the Eaton QC3080HT 80A 3-Pole 240 V Circuit Breaker delivers decisive protection for demanding loads. Built to interrupt fault currents quickly and halt unsafe conditions, this unit helps safeguard wiring, equipment, and personnel in commercial and light industrial environments.

Key specifications

• Part Number: QC3080HT
• Current rating: 80 A
• Poles: 3
• Voltage rating: 240 V

The 3-pole configuration ensures all conductors in a 3-phase circuit disconnect together, reducing phasing risks and helping maintain stable system protection across the entire feeder. The 80-amp rating is well-suited for substantial loads common in three-phase distribution, motor circuits, and large equipment feeders, providing a balanced approach to safety and performance.

Ideal use cases

• Three-phase feeders in commercial electrical panels and electrical rooms
• Motor control circuits and large equipment feeders operating at 240 V
• Power distribution points that require synchronized disconnection across all phases

Practical considerations and tips

• Match this breaker to a compatible Eaton panel or enclosure that supports QC-series devices and 3-pole, 240 V configurations.
• When upgrading or replacing, ensure the new breaker shares the same current rating (80 A) and pole count (3) to maintain system protection integrity.
• Perform a full load calculation to confirm the 80 A rating aligns with actual demand, and leave room for future expansion.
• Consult a licensed electrician for proper installation, labeling, and compliance with local electrical codes.

With the Eaton QC3080HT 80A 3-Pole 240 V Circuit Breaker in your protection lineup, you gain precise overload and short-circuit interruption for three-phase circuits, helping you reduce downtime and safeguard critical equipment. A reliable choice for professionals who demand clarity, performance, and consistent protection in high-load electrical environments.
