QOU2100 - 100 Amp Circuit Breaker

QOU2100 - 100 Amp Circuit Breaker

Some electrical jobs call for a breaker that does more than fit a panel. You need the right amperage, dependable circuit protection, and a mounting setup that works with your equipment. That's where the Square D QOU2100 100 Amp 2-Pole Circuit Breaker comes in. Made by Schneider Electric, this QOU series breaker is designed for residential and commercial electrical applications requiring a unit-mounted, two-pole breaker.

Key Features and Benefits

• 100-Amp, Two-Pole Protection: Designed for electrical systems that require a 100A, two-pole circuit breaker.
• Thermal-Magnetic Trip Mechanism: Helps protect circuits against overloads and short circuits.
• VisiTrip Indicator: Shows when the breaker has tripped, making it easier to identify the affected circuit.
• Multiple Mounting Options: DIN rail, surface, or flush-mount options with compatible mounting hardware.
• Unit-Mount Design: A good fit for electrical assemblies that use individually mounted QOU breakers.
• Copper or Aluminum Connections: Slotted box lugs accommodate either conductor material within the approved size range.
