Square D QO220 20A 2-Pole Plug-In Breaker for QO Panels

Square D QO220 20A 2-Pole Plug-In Breaker for QO Panels

Need a 20 amp 2-pole breaker for a QO panel? The QO220 drops right into your QO load center or NQ panelboard, no bolts or DIN rail needed. It is a thermal-magnetic breaker rated 120/240VAC with a 10kA interrupt rating, built to handle 240V loads like water heaters, HVAC condensers, and dryers.

Common trip means both poles kill the circuit together on a fault, and the Visi-Trip indicator tells you at a glance whether it tripped or just got switched off. Pressure plate terminals take 14 to 8 AWG copper or aluminum, so it fits most residential and light commercial branch circuits you are already running.

Common Applications

• 240V branch circuits: water heaters, dryers, HVAC condensers
• HACR-rated circuits for heating, air conditioning, and refrigeration equipment
• Panel fill-ins and breaker swaps in QO load centers and NQ panelboards
• Service upgrades and remodel work needing a 20A 2-pole slot

Key Features

• Plug-in fit: Snaps into QO load centers without bolts or DIN rail, faster on the job.
• Visi-Trip indicator: Center handle position and visual flag show a tripped breaker at a glance.
• Common trip 2-pole: Both poles open together, so the full 240V circuit de-energizes on a fault.
• 10kA interrupt rating: Handles fault current at 120/240VAC without issue.
• Pressure plate lugs: Takes 14-8 AWG copper or aluminum, no proprietary connectors.

FAQ

• Will the QO220 fit my QO panel?
  Yes, it is a direct plug-in fit for QO load centers and NQ panelboards, no bolt-on kit required.
• What size wire can I land on the QO220?
  The pressure plate lugs take 14 to 8 AWG copper or aluminum.
• Can I use the QO220 on an HVAC circuit?
  Yes, it is HACR rated for heating, air conditioning, and refrigeration equipment circuits.
• What does the Visi-Trip indicator do?
  When the breaker trips, the handle centers and a red indicator shows in the case window so you can tell it tripped instead of just being switched off.
• Is this a GFCI or AFCI breaker?
  No, the QO220 is a standard thermal-magnetic breaker. Square D sells separate QO GFCI and AFCI breakers if you need that protection.
