How to Install the ABB Q Line QC Circuit Breaker (THHQC22045WL)
Step-by-step guide to mounting and wiring the ABB Q Line QC 45A circuit breaker on a 35mm DIN rail.
Estimated time: 15m
Tools needed:
Screwdriver, Wire strippers, Crimping tool
Supplies needed:
35mm DIN rail, Mounting screws, Copper wire (appropriate gauge)
- Prepare the DIN rail
Ensure the 35mm DIN rail is securely mounted in the panelboard or enclosure. Verify the rail is level and free of obstructions.
- Mount the circuit breaker
Align the breaker's DIN rail clip with the rail and snap it into place. Apply even pressure until the breaker is fully seated and locked.
- Connect the wires
Strip the insulation from the incoming and outgoing wires to the appropriate length. Insert the wires into the lug terminals and tighten securely using a screwdriver. Ensure proper torque (refer to ABB's torque specifications).
- Verify the installation
Visually inspect the connections to ensure no loose wires or exposed conductors. Perform a continuity test to confirm proper wiring. Reset the breaker to the 'ON' position after installation.
