Schneider Electric QO245GFI Mini Circuit Breaker 45A

Product Description

The SCHNEIDER ELECTRIC QO245GFI is a QO-series miniature ground fault protecting circuit breaker rated for 45 amps at 120/240 volts AC, 50/60 Hz. It is designed for plug-in mounting in QO load centers and provides both overcurrent and ground fault protection in a single device. The breaker carries a 10 kiloamp interrupting rating and meets UL and CSA approval standards. Licensed electricians install this device as part of branch circuit protection in residential and light commercial electrical panels. Its NEMA 1 enclosure rating suits indoor applications where the panel is not exposed to weather or liquids.

The QO245GFI fits QO-style load centers in residential and light commercial settings. It is used where code requires ground fault circuit interrupter protection on branch circuits, such as bathroom, kitchen, garage, or outdoor circuits. The plug-in design allows straightforward replacement of standard QO breakers in existing load center installations without special tools or bus modifications. Electricians working on panel upgrades, service changes, or code-compliance retrofits will find this a direct-fit solution for QO-style panels.

Key Features

• 45-amp rating at 120/240 volts AC, 50/60 Hz for branch circuit overcurrent protection
• Integrated ground fault protection eliminates the need for a separate GFCI device on the circuit
• 10 kiloamp interrupting rating for reliable fault clearing
• Plug-in mounting for fast installation in QO load centers
• UL and CSA listed for compliance with NEC and Canadian electrical code requirements
• NEMA 1 enclosure rating suitable for indoor, dry-location panel installations

Compatibility

Designed for plug-in installation in Square D QO-style load centers. Consult the load center labeling and NEC requirements to confirm this breaker type and amperage are appropriate for the intended circuit application.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code and applicable local codes. Shut off the main breaker and verify the bus is de-energized with a non-contact voltage tester before handling any load center components. Snap the breaker firmly onto the QO bus bar until fully seated and torque all wire terminations to the values specified on the load center label. Do not install this breaker in panels that are not rated for QO plug-in devices.
