Eaton QBHW3020H - 20A, 240VAC, 3-Pole, Circuit Breaker

Eaton QBHW3020H — 20A, 240VAC, 3-Pole Circuit Breaker

The Eaton QBHW3020H delivers reliable overcurrent protection for 3‑phase electrical systems. With a 20 amp rating at up to 240 VAC and a 3‑pole configuration, this circuit breaker is purpose-built for panelboards, switchboards, and control panels in demanding industrial, commercial, and OEM environments. Designed to keep motors, drives, and other critical loads safe, it helps prevent costly downtime and equipment damage caused by short circuits and overloads.

Key features that matter in the field

• 3-Pole configuration for 3‑phase protection — ideal for distribution panels and motor control centers that run on three-phase power.
• 20A, 240VAC rating — precise overload protection aligned with common industrial equipment loads and motor circuits.
• Durable, reliable protection — built to perform in demanding environments where dependable operation is essential.
• Versatile installation compatibility — suitable for use in panelboards, switchboards, and control panels across a broad range of applications.

Use cases and ideal applications

This breaker is well-suited for three-phase motors, conveyors, pumps, HVAC equipment, and other equipment found in manufacturing floors, processing plants, and large commercial facilities. OEM equipment designers can rely on the QBHW3020H to provide consistent protection in custom control panels and integrated electrical assemblies.

Why choose the QBHW3020H over other options

Unlike single- or two-pole breakers, the 3‑pole configuration aligns with three-phase systems, delivering synchronized protection across all three lines. Its rating and design are tailored for panelboard environments where space, performance, and safety matter most, helping streamline wiring, reduce nuisance trips, and support safer maintenance routines in motor control centers.

Practical considerations and tips

When integrating the QBHW3020H, match the breaker rating to the continuous load and the motor’s full-load current to ensure proper protection without unnecessary tripping. Ensure the panelboard, switchboard, or control panel design accommodates a 3‑pole device, and verify compatible mounting and bus interface for seamless installation in existing electrical infrastructure.

With the Eaton QBHW3020H in your distribution setup, you’re choosing a trusted solution that prioritizes safety, reliability, and smooth operation for three-phase systems across industrial and commercial environments.
