How to Install the ABB THHQC2170WL Circuit Breaker
Step-by-step guide for mounting and wiring the THHQC2170WL on a 35mm DIN rail.
Estimated time: 15m
Tools needed:
Phillips screwdriver, Wire strippers, Crimping tool
Supplies needed:
35mm DIN rail, 12 AWG or larger copper wire, Cable lugs (if required)
- Prepare the DIN Rail
Ensure the 35mm DIN rail is securely mounted in the panel and free of obstructions.
- Mount the Circuit Breaker
Align the THHQC2170WL with the DIN rail and snap it into place until it clicks securely.
- Connect the Wires
Strip the wire ends to the appropriate length, insert them into the lug terminals, and tighten the screws to the manufacturer’s specified torque (typically 25-30 in-lbs).
- Verify Connections
Gently tug the wires to ensure they are secure. Check that the breaker is properly seated on the DIN rail.
- Test the Installation
Turn the breaker to the ON position and verify that the circuit is operational. Reset the breaker if it trips during initial testing.
