Core specifications

Current rating: 20 A
Poles: 2
Voltage rating: 240 V
Part number: QC2020B

Why a 2-Pole 240V breaker matters

For 240V circuits, a two-pole breaker ensures both hot conductors are simultaneously disconnected, which enhances safety during maintenance and reduces the risk of arc flash or equipment damage. The 20A rating is well-suited for common industrial loads, offering dependable protection without nuisance trips when used within its designed application.

Ideal use cases

• Industrial control panels and electrical distribution boards
• Motors, conveyors, pumps, heaters, and other 240V equipment up to 20A
• Replacements or upgrades in existing 2-pole 240V circuits
• New installations needing robust, straightforward overcurrent protection

Practical considerations

Ensure compatibility with your panel’s mounting and bus system and follow local electrical codes during installation. The QC2020B is designed for standard industrial panel environments and aligns with common 240V, 20A protection needs.

What you gain

• Reliable protection against overloads and short circuits for connected equipment
• Safer servicing with simultaneous disconnection of both hot lines on 240V circuits
• Clear part identity with the QC2020B designation for easy sourcing and inventory

Maintenance and longevity tips

Use within its rated 20A to minimize nuisance trips, and perform periodic inspections of connections and terminal tightness per your maintenance schedule. Replace the breaker if you notice frequent trips or signs of wear to maintain optimal protection for your system.

Choose the QC2020B for precise, 20A, 2-pole protection on 240V circuits, and keep your industrial electrical systems safeguarded with a trustworthy, purpose-built component.
