Built for commercial and industrial applications, the Square D QOU260 provides standard 10 kAIC interrupting capacity at 120/240VAC. This 60-amp, two-pole miniature circuit breaker ensures dependable long-time and instantaneous trip functions. The versatile unit-mount construction allows it to be easily integrated into DIN rail systems, control panels, and OEM enclosures. A built-in Visi-Trip indicator provides clear visual confirmation when the breaker has tripped, minimizing downtime.
What is the required tightening torque for the terminal lugs on the QOU260?
The box lugs on the QOU260 require a tightening torque of 45 lb-in (5.08 Nm). This applies when securing 14-2 AWG aluminum or copper conductors.
Can the QOU260 be installed in standard Square D QO load centers?
No. The QOU260 is a unit-mount circuit breaker designed for OEM enclosures, control panels, and DIN rail systems. Standard Square D QO load centers require plug-on breakers, while QOB panelboards require bolt-on-to-bus configurations.
How is the QOU260 breaker typically mounted?
As a unit-mount breaker, it can be attached directly to standard DIN rail systems, or it can be surface-mounted or flush-mounted inside OEM panels using the appropriate mounting foot accessories.
Which mounting bracket is required to surface-mount the QOU260?
To surface-mount or flush-mount this 2-pole unit, you will need the Square D QOUMF2 mounting foot, which is designed specifically for 2-pole QOU circuit breakers.
Is the Square D QOU260 circuit breaker HACR rated?
Yes, the QOU260 is HACR rated, meaning it is certified and tested for safe overcurrent protection of heating, air conditioning, and refrigeration equipment.
Can this breaker be used in DC control panels?
Yes. In addition to AC power systems, the QOU260 is dual-rated for DC applications up to 48VDC (with a 5 kAIC rating), making it suitable for use in certain telecommunications and industrial control panels.
Does the QOU260 feature a visual trip indicator?
Yes, it includes the Square D Visi-Trip indicator. When a fault or overload causes the breaker to trip, a red indicator window appears and the handle moves to a center position, allowing electricians to quickly identify the tripped circuit.
