Product Details

I. Product Overview

The ABB 3AFP9876489 is a PT100 platinum resistance temperature detector (RTD) from ABB, with material number 3AFP9876489. This sensor is a PT100 platinum RTD with a resistance of 100Ω at 0°C, conforming to IEC 60751 standard, used for temperature monitoring and overtemperature protection of key components such as windings and bearings in industrial motors, generators and drive systems.

PT100 RTD sensors measure temperature based on the property of platinum that its resistance varies with temperature, offering high accuracy, good stability and wide measuring range. In ABB motor and drive systems, PT100 sensors are typically used in conjunction with temperature relays or the temperature monitoring function built into variable frequency drives to provide overtemperature protection for motors/generators.

The 3AFP9876489 carries an official ABB material number (3AFP code system), suitable for temperature monitoring spare part replacement of corresponding generator, motor and drive equipment. For specific measuring range, wiring (2/3/4-wire), protection tube dimensions, mounting method and other technical parameters, please contact via email for confirmation.
