Description
QO and QOB one, two and three pole thermal magnetic circuit breakers provide overcurrent protection and switching on ac and dc systems. These circuit breakers have an over center, trip free toggle mechanism with quick make, quick break action and positive handle indication. They also have VisiTrip trip indication, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit. This 1 pole QO circuit breaker is rated at 25A at 120/240VAC. This unit provides 10kA breaking capacity and plug in mounting. A full line of features and factory installed accessories are also available such as shunt trips, auxiliary switches and alarm switches. QO circuit breakers are UL Listed under UL File E84967 and are CSA Certified under CSA Master Contract 153555.

Features
- This high-quality breaker features Square D’s patented VisiTrip™ indicator mechanism, which deploys a highly visible, red flag into the face of the toggle handle window the moment the circuit shuts down. This instant visual diagnostic allows residential and commercial electricians to identify the faulted branch circuit immediately in a dark basement or maintenance closet, avoiding tedious multimeter troubleshooting and minimizing client downtime.
- Engineered exclusively for the industry-standard 3/4-inch QO chassis, this 1-pole plug-in breaker features a robust pressure-fit terminal jaw that snaps effortlessly onto the copper panel bus bars. Homeowners and service electrical contractors can complete rapid, tool-free branch additions or legacy replacements with perfect mechanical alignment, saving premium labor time while securing a low-resistance electrical connection.
- Delivering a precise 25-amp current rating at 120/240V AC, this thermal-magnetic breaker relies on a dual-action safety system to protect structural wiring.
- Built with a robust 10,000-amp (10 kAIC) short-circuit interrupting rating, this protective device is fully equipped to safely isolate high-energy electrical faults without destructive casing failure. It provides vital protection against cascading grid damage, meeting modern Canadian electrical installation codes for multi-family dwellings and commercial retail panels.
- This specialized breaker carries a factory-certified HACR rating, explicitly certifying its internal trip curve to tolerate the high inductive inrush currents associated with heating, air conditioning, and refrigeration compressor motors. This designation eliminates nuisance tripping caused by initial equipment startup spikes, making it an excellent fit for dedicated residential heat pumps or light-commercial HVAC circuits.
- The load terminal is fitted with a heavy-duty, versatile pressure plate assembly that securely terminates a wide wire gauge spectrum from 14 AWG down to 8 AWG in both copper and aluminum conductors. Rated for a maximum tightening torque of 35.4 lbf.in (4 N.m), the robust clamp prevents localized wire deformation, ensuring a permanent gas-tight connection that eliminates loose-terminal arcing faults over years of service.
