Product Dimensions：

The GE THQL32080 is a high-quality, plug-in Miniature Circuit Breaker (MCB) from GE’s long-standing Q-Line panelboard family (now managed under the ABB portfolio following their acquisition of GE Industrial Solutions). It is designed to provide reliable overcurrent and short-circuit protection for residential, commercial, and light industrial applications.

Product Detailed Description

The THQL32080 is a 3-Pole (3P) circuit breaker that occupies three standard 1-inch spaces in a compatible GE load center or panelboard. It features a 80 Amp current rating and utilizes a thermal-magnetic tripping mechanism. The thermal element provides time-delayed protection against sustained overloads, while the magnetic element ensures instantaneous tripping during severe short-circuit faults.

Technical Parameters

Product Advantages

• Easy Installation: The plug-in design allows for fast, secure, and tool-free mounting onto the bus bars of standard GE load centers.
• Box Lug Terminals: Equipped with heavy-duty box lugs that feature robust screw clamps, ensuring high-integrity cable connections and reducing the risk of hot spots.
• Dedicated 3-Pole Protection: Features a common trip mechanism; if a fault occurs on any single phase, all three poles trip simultaneously to prevent dangerous “single-phasing” conditions for three-phase equipment.
• High Contained Reliability: Q-Line breakers are built with a rugged, arc-resistant thermoset case that enhances safety and extends the physical lifespan of the device under harsh electrical conditions.

Important Considerations & Precautions

• Panel Compatibility: This breaker is strictly designed for GE Q-Line load centers (such as PowerMark Gold panels). It will not physically fit or sit safely in panels from other manufacturers (e.g., Square D, Siemens, or Eaton) despite similar appearances.
• Interrupting Capacity: With a 10 kA interrupting rating, ensure the calculated prospective short-circuit current at the installation point does not exceed 10,000 Amps. For high-fault commercial zones, a THHQL (22 kA) or higher variant may be required.
• Conductor Material: The terminals are rated AL/CU, meaning they can accept both Aluminum and Copper wiring. If using Aluminum, always apply an approved anti-oxidant joint compound to prevent terminal corrosion.
• Torque Specifications: Always check the face of the breaker or the panel door label for exact wire terminal torque requirements. Under-torquing leads to high resistance and heat, while over-torquing can damage the conductor.

Product Applications

The 80A 3-pole configuration is typically utilized for feeding substantial sub-panels or heavy branch loads:

• Commercial HVAC Units: Protecting and isolating large central air conditioning compressors and commercial ventilation systems.
• Three-Phase Motors: Providing overcurrent protection for medium-sized industrial motors, pumps, and machinery.
• Sub-Panel Feeders: Serving as the main feeder breaker in a primary panelboard to route power down to a smaller 240V 3-phase sub-panel.
• Industrial Kitchens: Powering high-draw electrical loads such as commercial ovens, walk-in freezers, and industrial dishwashers.
