Siemens 3RT7017-1AG01 — Size S00 Contactor for Motor and Resistive Loads
The Siemens 3RT7017-1AG01 is a Size S00 contactor with three normally open main poles, screw-type terminals for the main and auxiliary circuits, and a rated insulation voltage of 690 V. It mounts on a 35 mm DIN rail (DIN EN 50022) via screw or snap-on fastening, and its 45 mm width fits tightly into a crowded panel — the S00 frame is the smallest in the SIRIUS family, sized for light motor and resistive loads up to 690 V AC-3 / AC-3e. Switching capacity is voltage-dependent: at 230 V rated value it handles 6 A, at 400 V rated value 3 A, and at 690 V rated value 1 A. The AC-3 and AC-3e maximum operating voltage is 690 V, so the contactor is suited for 400 V motor circuits with moderate inrush — the 3 A at 400 V is the figure to size against for a standard three-phase motor branch.
Panel Integration and Environmental Ratings
The contactor is IP20 on the front and at the terminals — finger-safe for panel interiors but not washdown-rated. Operating temperature spans -10 to +55 °C, storage from -25 to +70 °C. Pollution degree 3 means it tolerates conductive dust and condensation typical of industrial enclosures without conformal coating. Mounting position is flexible: ±180° rotation on a vertical surface, and can be tilted forward/backward by ±22.5°. Side-by-side mounting is permitted, so you can gang multiple S00 contactors without derating for heat buildup — useful for compact motor control centers.
Lifecycle and Sourcing
For BOM planning, the 3RT7017-1AG01 is sourced to order against an RFQ. Availability and current pricing are confirmed at quote time through independent distribution. No second-source cross-reference is officially published, but the SIRIUS S00 family shares the same footprint and terminal layout, so a parametric substitute within the same frame size is straightforward.
