Q23020CT2 - 2P/30A-2P/20A Quad Circuit Breaker Description

Q23020CT2 - 2P/30A-2P/20A Quad Circuit Breaker

If you've ever opened up a crowded panel and thought, "There's no way I'm fitting another breaker in here," the Q23020CT2 quadplex circuit breaker is exactly the kind of solution you're looking for. This breaker is built for efficiency—giving you four circuits in the space of two, while still delivering the dependable protection your system needs. With a 30/20 amp configuration, it's ideal for handling mixed-load applications without forcing you to compromise or rework your entire panel setup. What really sets it apart is its common trip design. When one side trips, the connected circuit goes with it—keeping things safer, especially in multi-wire branch circuits where coordination matters. Add in a 10kA interrupting rating at 120/240VAC, and you've got a breaker that's ready to step in when it counts most. Whether you're upgrading a panel, replacing a worn unit, or trying to maximize every inch of space, this is one of those components that just makes your job easier.

Key Features and Benefits

  • Maximize Panel Space Without the Headache
    Quadplex design lets you run four circuits while using minimal space.
  • Flexible 30/20 Amp Setup
    Perfect for applications that require different amperage circuits in one breaker.
  • Common Trip Safety
    Both connected circuits trip together—helping prevent imbalance and potential hazards.
  • Strong Fault Protection (10kA Rating)
    Built to safely interrupt high fault currents and protect your equipment.
  • Quick Plug-In Installation
    Drops right into compatible panels, saving time on installs or replacements.
  • HACR Rated for HVAC Use
    Suitable for heating, air conditioning, and refrigeration circuits.
  • Performs in Warmer Environments (40°C Rated)
    Designed to hold up under real-world operating conditions.
