Siemens 3RT1064-2AB36 SIRIUS Power Contactor 3P 225A 110kW 23-26V DC

The Siemens 3RT1064-2AB36 (MLFB: 3RT1064-2AB36) is a SIRIUS 3RT1 series power contactor rated at 225 A / 110 kW at 400 V AC-3e/AC-3. It is a 3-pole contactor with a 23-26 V DC control coil, designed for switching three-phase motors and resistive loads. The auxiliary contact arrangement is 2 NO + 2 NC, and the main circuit uses busbar terminals while the control and auxiliary circuits use spring-loaded terminals.
