3TF54 contactor siemens

Description :

The Siemens 3TF54 is a 3-phase IEC rated contactor used for the control of electric motors. It is rated 100 HP at 230V and 200 HP at 460V.


Power contactors are suitable for switching and controlling squirrel cage and slip-ring motors as well as other AC loads, such as solenoids, capacitors, lighting loads, heating loads and transformer loads

Selection and ordering data

High performance

1. No duration upto 55°C
Contactors are suitable for operation in service temperature up to 55°C without derating. This avoids selection of higher rated contactor, thereby reducing cost.

2. Long Life
Superior design of current carrying parts, contact system and the magnet system increases the reliability results into higher electrical and mechanical endurance.

3. High short-time rating
Contactors have a high short-time rating, which makes them suitable for applications having high starting currents and long run-up times.
