How to Install the ABB THQC32070WL Circuit Breaker

Step-by-step guide to mounting and wiring the ABB Q Line THQC32070WL 70A circuit breaker on a 35mm DIN rail.

Estimated time: 15m

Tools needed:

Screwdriver, Wire strippers, Crimping tool

Supplies needed:

Mounting screws, Copper wire (6 AWG recommended for 70A), Wire connectors

  1. Prepare the DIN rail

    Ensure the 35mm DIN rail is securely mounted in the panelboard or distribution board. Verify the rail is level and free of obstructions.

  2. Mount the circuit breaker

    Align the THQC32070WL with the DIN rail and snap it into place. Apply firm pressure until the breaker locks securely onto the rail.

  3. Connect the wires

    Strip the insulation from the load and line wires (6 AWG recommended for 70A). Insert the wires into the lug terminals and tighten the screws to the manufacturer’s specified torque (typically 25-30 in-lb).
