QOU230 - 30 Amp Circuit Breaker

QOU230 - 30 Amp Circuit Breaker

Not every circuit breaker belongs in a standard load center. Some installations require a breaker that can be mounted directly inside an electrical enclosure, on a DIN rail, or as part of a custom equipment assembly. That's where the Square D QOU230 30 Amp 2-Pole Circuit Breaker comes in.

The QOU230 also includes Square D's VisiTrip indicator. When the breaker trips, a visual indication helps you spot the affected circuit. It's useful when you're checking equipment, tracking down an electrical problem, or getting a system back into service.

Key Features and Benefits

• 30-Amp, Two-Pole Design: Provides overcurrent protection for compatible circuits that require a 30A, two-pole breaker.
• Thermal-Magnetic Protection: Responds to overloads and short circuits, helping protect wiring and connected equipment from excessive current.
• VisiTrip Indicator: Makes a tripped breaker easier to identify, so troubleshooting starts with less guesswork.
• Flexible Mounting: Works with DIN rail, surface-mounted, and flush-mounted arrangements with the proper mounting hardware.
• Copper or Aluminum Connections: Slotted box lugs on the line and load sides accept approved conductors from 14 AWG through 2 AWG.
• AC and DC Operational Voltage Ratings: Rated for 120V AC, 120/240V AC, and 48V DC operation, depending on application requirements.
