Siemens 3RT1017-2AG62 SIRIUS Power Contactor — Size S00, Spring-Loaded Terminals
The Siemens 3RT1017-2AG62 is a SIRIUS power contactor in the compact Size S00 frame, rated for 5.5 kW motor switching at 400 V under AC-2 duty — the standard category for slip-ring motors and moderate jogging applications. Spring-loaded terminals on the main circuit accept 2x (0.25...2.5 mm²) solid or stranded wire, which speeds panel wiring and eliminates the need for screw-torque checks on the line side.
Motor Duty and Coordination
At 400 V AC-3 (standard squirrel-cage motor start/run), this contactor switches 5.5 kW; under AC-4 reversing or inching duty, the rated operating current drops to 8.5 A. The 10 A AC-12 rating covers resistive loads like heater banks or control transformers.
The front and terminal areas carry IP20 finger-safe protection, so the contactor can sit on an open panel door without additional shrouding. Operating temperature spans -25 to +60 °C, with storage down to -55 °C; altitude limit is 2 000 m without derating.
