THQLQ153015 - Quad 15A-30A-15A Circuit Breaker

THQLQ153015 - Quad 15A-30A-15A Circuit Breaker

The THQLQ153015 quadplex circuit breaker is a simple way to add more circuits without cramming your panel. Instead of using multiple breaker spaces, this unit gives you three circuits in one—two 15-amp single poles on the outside and a 30-amp double pole in the middle. It’s a practical setup if you’re running a mix of standard and 240V loads and don’t have much room left in the panel. It installs with a plug-on connection, so there’s nothing unusual about getting it in place if you’ve worked with Q-Line breakers before. The build is solid and does what you expect—protects your circuits from overloads and shorts without any fuss. It’s also HACR-rated, making it a common pick for HVAC equipment and similar systems where reliability matters.

Key Features and Benefits

• Three circuits built into one breaker (15A / 30A / 15A): Combines multiple circuits into a single unit for efficient use of panel space.
• Saves space inside crowded panels: Ideal for setups where available breaker slots are limited.
• Straightforward plug-on installation: Designed for easy installation with standard Q-Line compatibility.
• Works well for both 120V and 240V circuits in one spot: Supports mixed voltage applications in a single breaker position.
• HACR rated for HVAC and refrigeration use: Suitable for systems where consistent performance is important.
• Keeps panel layouts simpler and more organized: Reduces clutter and improves panel arrangement.

Where It Works Best

This breaker makes the most sense in residential panels, apartment units, or small commercial setups where space is already tight. It’s commonly used for HVAC systems, shared circuits, or anywhere you need both 120V and 240V lines without adding more breaker slots.
