Siemens 3RT1064-6AB36 Three-Phase AC Contactor

Siemens 3RT1064-6AB36 is a three‑pole power contactor rated for AC‑3e/AC‑3 duty at 225 A (approximately 110 kW at 400 V, 50–60 Hz). The coil is a 23–26 V DC control voltage (Uc), enabling reliable energization from low‑voltage control circuits, and the unit includes two normally open and two normally closed auxiliary contacts for signaling and interlocking. Main and auxiliary circuits terminate on screw terminals, and the device is designed for DIN rail or fixed mounting, suitable for panel‑mounted motor control in industrial installations. It integrates with Siemens SIRIUS 3RU2 overload relays and 3RV2 motor‑protection circuit breakers to form coordinated direct‑on‑line and reversing starters.
