Siemens 3RT1017-1AV01 Contactor

Siemens 3RT1017-1AV01 is a 3-pole power contactor in size S00, rated for AC-3 duty to switch motors up to 5.5 kW at 400 V. It features three normally open main contacts and one normally open auxiliary contact, with screw-terminal connections for reliable wiring. The unit is IP20 front-rated, belongs to pollution degree 3, and is designed for ambient temperatures from -25 to +60 C and installation up to 2,000 m above sea level. Mechanical life is around 30,000,000 operating cycles for the base contactor, 10,000,000 with an added auxiliary switch block, or 5,000,000 with electronics-compatible auxiliary blocks. Rated currents include 22 A at AC-1 (400 V), 20 A at 60 C, and 12 A at AC-3 (400 V). This makes it well-suited for controlling small to medium motors in industrial equipment, conveyors, or machine tools where compact S00 sizing and reliable motor switching are required.
