ABB Thermal Overload Relays for Motor Protection

ABB thermal overload relays are used with contactors to protect electric motors against overload and phase failure. They are commonly fitted in motor starters, MCC panels, pump panels, compressors, conveyors and industrial machines where reliable motor overload protection is required.

The relay is set according to the motor rated current. If the motor continues to draw excess current, the thermal overload relay trips and opens the contactor control circuit, helping prevent overheating and motor damage.

ABB offers thermal overload relays for a wide range of motor currents, from small fractional motors through to larger industrial motors. The main range includes T16, TF42, TF65, TF96, TF140DU and TA200DU.

For an ABB thermal overload relay supplier in India, ABB TF42 overload relay, TF65 motor protection relay, TF96 overload relay or ABB thermal overload relay export requirement, buyers can share the motor current, contactor model and required quantity for quotation.

• TF140DU-142 – 110–142 A

These relays are commonly used in larger motor starters, pumps, compressors and industrial drive applications.

ABB TA200DU Thermal Overload Relay

TA200DU extends the thermal overload relay range up to 200 A and is used with larger ABB contactors such as AF190 and AF205.

Models include:

• TA200DU-90 – 66–90 A
• TA200DU-110 – 80–110 A
• TA200DU-135 – 100–135 A

Using the correct contactor and overload relay combination gives panel builders a compact motor starter without additional wiring between the contactor and overload relay.

ABB Thermal Overload Relay for Motor Protection

A thermal overload relay is normally set close to the motor’s rated full-load current.

For example, if a motor operates at 24 A, the overload relay should have an adjustable setting range that covers 24 A. The exact setting should then be selected according to the motor nameplate and application requirements.

This is why buyers should provide the motor rated current or existing overload relay model when requesting a quotation.

Typical motor protection applications include:

• Pump motors
• Compressor motors
• Conveyor motors
• Fans and blowers
• Machine motors
• HVAC equipment
• Process machinery
