Siemens 3RT1065-6AP36 Three-Phase Power Contactor

The Siemens Sirius 3RT1065-6AP36 is a three‑pole power contactor designed for AC‑3 motor control in industrial drives, rated up to 265 A at 400 V and delivering up to 132 kW at 400 V (50/60 Hz) for motor starting and running in a compact S10 frame.

It uses 3 main normally‑open contacts and 2 normally open plus 2 normally closed auxiliary contacts, with screw‑terminals for the main circuit and auxiliary circuit and busbar compatibility for streamlined panel wiring.

The coil is a 220–240 V unit (UC) suitable for 50/60 Hz operation, with insulation voltage up to 1000 V and surge resistance of 8 kV on the main circuit and 6 kV on auxiliaries; it supports up to 10,000,000 mechanical operating cycles (5,000,000 cycles for electronics‑friendly auxiliary configurations) and operates in ambient -25 to +60 C with pollution degree 3.

Overall dimensions for the size S10 frame are about 210 mm high, 145 mm wide, and 202 mm deep, and the unit carries front protection rated at IP00 (with typical enclosure considerations in many installations), making it well suited for OEM equipment and industrial control panels requiring robust motor switching.
