QO2020 - Square D 20A/20A Tandem Circuit Breaker, 120/240V, 1-Pole, QO Series, Plug-In Mount, 10kA Interrupt, VISI-TRIP, CSA/UL Listed

Product Overview

The QO2020 is a Square D QO Series tandem (skinny) breaker that provides two 20A, 1‑pole circuits in a single plug‑in module for 120/240V panels.

Designed for QO plug‑in load centers, the unit features a 10kA interrupting rating and VISI‑TRIP trip indication. It is CSA and UL listed.

Key Features

• Two independent 20A, 1‑pole circuits in a tandem configuration (single module)
• QO Series plug‑in mounting for compatible Square D QO load centers
• 10,000 A interrupting rating
• VISI‑TRIP visible trip indication
• CSA and UL listed

What this breaker does

The QO2020 provides two separate 20‑ampere, single‑pole circuits in a single tandem breaker module. Each pole supplies a 120V circuit when installed in compatible QO panels. The unit is intended to conserve full‑size breaker spaces where tandem/skinny breakers are permitted by the panel manufacturer and local code.

• Two independent 20A circuits in one QO module
• Single‑pole configuration for 120V branch circuits

Panel compatibility and mounting

This breaker uses the QO Series plug‑in mounting system. It is intended for use in Square D QO load centers and panels that explicitly allow tandem breakers in the target slot. Compatibility depends on the specific panel model and the panel manufacturer's instructions.

• Plug‑in QO Series mounting
• Confirm the panel permits tandem/skinny breakers in the chosen slot

Electrical rating and performance

The QO2020 is rated for 120/240V service and provides two 20A, 1‑pole circuits. The breaker has a 10,000 ampere interrupting rating (10kA), suitable for many common residential and light commercial distribution applications where this interrupting rating meets the available fault current at the service.

• Voltage: 120/240V
• Amperage: 20A per pole
• Pole count: 1‑pole (two independent poles in a tandem module)
• Interrupting rating: 10 kA

Certifications and trip indication

The QO2020 carries CSA and UL listings. It also features Square D's VISI‑TRIP trip indication which provides a visible signal when the breaker has tripped.

• VISI‑TRIP visible trip indicator
• CSA listed
• UL listed

Ordering notes and verification

Confirm the exact panel model and the number of tandem breaker positions allowed before placing an order. Verify the QO2020 part number matches the requirement for your application.

• Confirm panel model and tandem allowance
• Verify you require two 20A, 1‑pole circuits in a single module
• Confirm part number QO2020 before ordering

Before You Order

Confirm the model number and quantity required before ordering. Ensure the target Square D panel accepts tandem QO breakers in the desired position and that a 10 kA interrupting rating is acceptable for your service fault current.

• Verify panel model and tandem/skinny breaker allowance
• Confirm the application requires two 20A 1‑pole circuits in one module
• Match part number QO2020 to installation plans
