How to Install the ABB THHQC2150LL Circuit Breaker
Step-by-step guide for installing the ABB THHQC2150LL 50A 1-pole Q Line QC circuit breaker on a 35mm DIN rail.
Estimated time: 15m
Tools needed:
Phillips screwdriver, Wire strippers, Crimping tool (if needed)
Supplies needed:
35mm DIN rail, Electrical cables (as required), Mounting screws (if applicable)
- Prepare the DIN rail and panel
Ensure the 35mm DIN rail is securely mounted in the electrical panel. Verify that the panel is de-energized and locked out before installation.
- Mount the circuit breaker
Align the THHQC2150LL with the DIN rail and snap it into place. Apply firm pressure until the breaker locks securely onto the rail.
- Connect the cables
Strip the insulation from the electrical cables to the required length. Insert the wires into the lug terminals and tighten the screws to the manufacturer's specified torque (typically 20-25 in-lb for 50A breakers).
- Verify connections and test
Double-check all connections for tightness and proper seating. Energize the panel and test the breaker by toggling it to the ON and OFF positions to ensure smooth operation.
