Mounting the ABB TF42-24 Thermal Overload Relay
Step-by-step guide for mounting the TF42-24 relay.
Estimated time: 15m
Tools needed:
Screwdriver (M4 Pozidriv 2 for main circuit, M3 Pozidriv 2 for auxiliary circuit), Torque wrench (optional, for specified torque values)
Supplies needed:
ABB AF09...AF38 block contactor (for direct mounting), Single mounting kit (for DIN rail mounting), Appropriate conductors for main and auxiliary circuits
- Prepare for Mounting
Ensure the power supply to the motor circuit is de-energized. Select the mounting method: direct mounting onto an ABB AF09...AF38 block contactor or mounting on a 35 mm DIN rail using a single mounting kit.
- Mount the Relay
For direct mounting, align the TF42-24 relay with the corresponding block contactor and secure it by tightening the main circuit terminal screws to the specified torque (2.5 - 2.7 Nm).
- Connect Main Circuit Terminals
Strip the conductors to the specified length (12 mm for main circuit). Connect rigid conductors (1.5 to 2.5 mm² or 2.5 to 10 mm²) or flexible conductors with insulated ferrules (2.5 to 4 mm² or 4 to 6 mm²) to the main circuit terminals. Ensure proper tightening torque is applied.
- Connect Auxiliary Circuit Terminals
Strip the conductors to the specified length (9 mm for auxiliary circuit). Connect rigid conductors (1 or 2 x 0.75 to 4 mm²) or flexible conductors with ferrules (1 or 2 x 0.75 to 2.5 mm²) to the auxiliary circuit terminals. Ensure proper tightening torque is applied (1 - 1.2 Nm).
- Verify Connections and Settings
Double-check all electrical connections for security and correctness. Set the desired current range on the relay and select the manual or automatic reset function. Ensure the trip indication is visible.
