SQUARE D QOU260 60 A 48 V DC 2 Pole Miniature Circuit Breaker

SKU CH-7T8W-BE52J

A 60 A two-pole miniature circuit breaker rated for 48 V DC and 120/240 V AC with a 10 kA interrupting rating, DIN-rail or surface mountable in a QO panelboard

  • TypeCircuit Breakers
  • 60 A rating protects heavy-duty circuits from overload
  • 48 V DC rating supports low-voltage DC applications
  • 2-pole design disconnects both lines for safety
  • DIN rail or surface mounting fits standard panels
  • 10 kA interrupting capacity clears high fault currents

Square D QOU260 60 A Breaker

This Square D QOU260 is a 60 A miniature circuit breaker rated for 120/240 V AC and 48 V DC. It uses a standard two-pole design with a toggle actuator and belongs to the QOU series. The frame size is 100 A and the maximum AIR rating reaches 10 kA at 120/240 V AC. It is intended for air-conditioning, refrigeration and heating equipment.

Surface or DIN-Rail Mount with Reversible Lugs

The breaker mounts on a surface or DIN rail and measures 4.05 in. in length. Terminals are slotted box lugs with reversible line and load connections, so conductors can be landed from either direction. A common issue is forgetting to torque the lugs to the manufacturer’s specification, which can lead to overheating. Verify that the panelboard is a compatible QO series unit before installation.

For Single-Phase 60 A Circuits on QO Panels

This device suits installers protecting single-phase 60 A branch circuits in QO load centres, especially for HVAC and heating loads. It is not suitable for three-phase systems, for voltages above 240 V AC or 48 V DC, or for panels that do not accept QOU-series breakers. Buyers needing a different ampere rating, pole count or mounting style should select another model.

Questions about this item

How can I confirm the QOU260 is protecting the circuit after I mount it on the DIN rail?

Switch the toggle to the on position; the breaker will carry up to 60 A at 120/240 V AC or 48 V DC and trip automatically if current exceeds the 10 kA interrupting rating.

What comes with the QOU260 and what must I source separately?

The breaker itself includes reversible slotted box lugs for line and load; you must supply DIN rail or surface-mount hardware and the QO-series panelboard or load center it fits.

Which version of the QOU260 should I select for a 60 A, two-pole application?

The QOU260 is a single 60 A, two-pole model in the 100 A frame size; choose it when you need 48 V DC or 120/240 V AC protection in a QO-compatible panel.
