QOU380 - 80Amp Circuit Breaker

QOU380 - 80Amp Circuit Breaker

Finding the right circuit breaker isn't just about matching your amperage. Mounting style, voltage ratings, conductor compatibility, and available space all matter. The Square D QOU380 80 Amp 3-Pole Circuit Breaker combines those details in a compact, unit-mounted design for compatible residential and commercial electrical systems. Manufactured by Schneider Electric, this QOU-series miniature molded case circuit breaker provides overcurrent protection for 80-amp, three-pole applications, with a 10kA interrupting rating at 120V AC, 120/240V AC, and 240V AC.

Key Features and Benefits

• 80-Amp, Three-Pole Design: Provides overcurrent protection for compatible circuits requiring an 80A, three-pole circuit breaker.
• Thermal-Magnetic Protection: Responds to overloads and short circuits, helping protect electrical wiring and connected equipment from excessive current.
• VisiTrip Indicator: Makes a tripped breaker easier to identify, reducing guesswork during electrical troubleshooting.
• Flexible Mounting Options: Supports DIN rail, surface, and flush mounting with the appropriate mounting hardware.
• Copper and Aluminum Connections: Slotted box lugs on the line and load sides accommodate approved conductors from 12 AWG through 2/0 AWG.
• AC and DC Operational Ratings: Rated for 120V AC, 120/240V AC, 240V AC, and 60V DC operation, depending on application requirements.
