QOU130 - 30 Amp Circuit Breaker

QOU130 - 30 Amp Circuit Breaker

Need a dependable 30-amp breaker for a residential, commercial, or equipment installation? The Square D QOU130 by Schneider Electric is worth a closer look. This single-pole miniature molded case circuit breaker is rated for 30 amps, operates on 120V and 120/240V AC circuits, and has a 10,000-amp (10kA) AC interrupting rating. It's also rated for 48VDC applications, subject to the manufacturer's requirements. The QOU130 is especially useful for its versatility. Unlike breakers designed exclusively for a particular plug-on panelboard, this unit-mounted model supports DIN rail, surface, and flush mounting arrangements with the appropriate mounting provisions. With thermal-magnetic circuit protection, convenient box-lug terminals, and Square D's VisiTrip indicator, you get a practical breaker for installations where the details really matter.

Key Features and Benefits

• 30 Amp, Single-Pole Design: Provides overcurrent protection for compatible 30A circuits without taking up unnecessary space.
• Thermal-Magnetic Protection: Responds to sustained overloads and short circuits, helping protect properly sized conductors and connected equipment.
• VisiTrip Indicator: A visible trip indication helps you spot a tripped breaker without having to guess which circuit was interrupted.
• Flexible Mounting: Supports DIN rail, surface, or flush mounting with the proper mounting hardware. Handy when a standard plug-on breaker doesn't meet the installation requirements.
• AC and DC Voltage Ratings: Suitable for specified 120V and 120/240V AC circuits, plus appropriately rated 48VDC applications.
• Copper and Aluminum Wire Compatibility: Slotted box-lug terminals accommodate the manufacturer's specified 14 AWG through 2 AWG conductor range.
