Siemens SENTRON 5TT Contactor, 24 V ac/dc Coil, 4-Pole, 24 A, 2NO + 2NC, 400 V ac

The Insta contactors are the ideal switching device for con-trolling AC/DC control voltage in industrial applications and in-frastructure. In addition to their basic function, they can also be used for the On/Off switching of single-phase and three-phase electrical motors. The 5TT50 Insta contactors meet the requirements of EN 60947 and are approved to UL 508. The simultaneous switching of lamp loads at varying phases can be achieved with a single contactor, whereby it is essential to strive for/ensure a symmetrical load of the phases.
