Cutler-Hammer QCR3020H - 20A, 240VAC, 3-Pole, Circuit Breaker

Meet the Cutler-Hammer QCR3020H, a purpose-built 20A, 240VAC, 3-Pole circuit breaker designed for serious industrial and commercial use. Built to deliver dependable overcurrent protection in demanding environments, this breaker safeguards panelboards, switchboards, and control panels with precise, reliable performance when it matters most.

Key specifications at a glance

• Current rating: 20A
• Voltage rating: 240VAC
• Poles: 3-Pole
• Breaker type: Circuit Breaker

Why this 3-Pole design matters

In three-phase systems, the QCR3020H protects all three conductors in one compact unit, ensuring simultaneous interruption across phases during a fault. This coordinated protection minimizes motor stalling, gear wear, and unbalanced loads, helping to keep conveyors, pumps, and fans running smoothly when disturbances occur.

Practical benefits for real-world applications

• Versatile placement: Ideal for industrial panelboards, switchboards, and control panels where space and reliability are critical.
• Reliable protection for motor control centers: Helps prevent damage from overloads and short circuits in three-phase equipment common to manufacturing and processing facilities.
• OEM and commercial compatibility: A dependable choice for equipment assemblies and distribution systems that require consistent, predictable performance.
• Downtime reduction: Quick, decisive tripping limits equipment exposure to fault conditions, supporting faster recovery and safer operation.

Who benefits most

Operators and engineers working with three-phase machinery—such as motors, fans, pumps, and drives—in manufacturing plants, HVAC distribution, and automated systems will find the QCR3020H a precise fit. It’s also a solid option for OEM builders seeking a proven, compatible protection device within standard electrical distributions.

How it stands out vs. conventional breakers

Compared with single- or two-pole solutions, the three-pole configuration of the QCR3020H provides comprehensive phase protection for three-phase circuits in a single, compact breaker. The 20A/240VAC rating aligns with typical industrial branch circuits, delivering targeted protection without unnecessary nuisance trips on normal loads.

For reliable, industry-grade overcurrent protection in distribution panels and motor control centers, the Cutler-Hammer QCR3020H 20A, 240VAC, 3-Pole Circuit Breaker is a focused, durable choice designed to keep critical systems safe and operating smoothly.
