SQUARE D QO220VH 20 A double-pole breaker, light grey plastic housing, paddle actuator, plug-in base

SQUARE D

SQUARE D QO220VH 20 A 2 Pole 120/240 V circuit breaker

SKU CH-6FHJ-W0N9E

A 20 A, two-pole miniature circuit breaker with 22 kA interrupting capacity for QO load centres

  • High interrupting capacity protects circuits up to 22 kA
  • 2-pole design handles both 120 V and 240 V loads
  • Plug-in mounting fits QO load centres without tools
  • Pressure-plate terminals accept wires for secure connections
  • Rated 20 A at 120/240 V AC and 48 V DC

Product Identity

The SQUARE D QO220VH is a 20 A two-pole miniature circuit breaker rated for 120/240 V AC and 48 V DC. It is built for QO load centres and NQ panelboards where a 22 kA interrupting capacity is required.

Installation Notes

The plug-in mounting style fits directly onto compatible QO bus bars using a paddle actuator. Pressure-plate terminals accept wire without special tools. Misalignment with the bus or using the breaker in a non-QO panel will prevent proper seating and protection.

Interface Limits

The breaker operates on single-phase systems up to 120/240 V AC with a maximum AIR of 22 kA. It does not suit three-phase loads, voltages above 240 V AC, or DC circuits exceeding 48 V. The 100 A frame size caps the panel’s main rating, not the branch circuit.

Questions about this item

How can I confirm the QO220VH is functioning correctly after installation?

With power applied, measure 120/240 V AC across the two poles using a multimeter; the paddle should stay in the ON position and the breaker must not trip under normal load up to 20 A.

What comes in the box and what must I purchase separately?

The package contains the QO220VH breaker only; you will need to supply a compatible QO load centre or NQ panelboard, mounting hardware and appropriately rated conductors.

Which version should I choose for a 120/240 V AC circuit requiring high interrupting capacity?

Select the QO220VH rated 20 A, 2-pole, 120/240 V AC with a 22 kA AIR rating for high interrupting capacity on QO load centres and NQ panelboards.
