Product Positioning

The 3RT2017-1AF04 is a Siemens SIRIUS S00 frame AC contactor. Its main circuit has a rated current of 12A (AC-3) and can control a 5.5kW three-phase motor at 400V. It shares the same frame and main contact specifications as other models in the same series. This model has a coil voltage of 110V AC and is equipped with 4 sets of auxiliary contacts (2NO + 2NC), more than the standard single-contact model. It is suitable for 110V control circuits that need to handle multiple interlocking signals, fault reports, or HMI status displays simultaneously. Both the main and auxiliary circuits use screw terminals and can be installed on a 35mm standard DIN rail. Kenxin Motors provides genuine Siemens products and complete selection services.

Core Product Advantages and Features

110V AC coil

The coil has a rated voltage of 110V, making it suitable for common 110V control circuit power supply systems both domestically and internationally.

2NO+2NC four sets of auxiliary contacts

It provides four sets of auxiliary contacts at once, meeting multiple control needs such as indication, interlocking, and feedback, without the need to install additional contact modules.

12A/5.5kW main circuit

The AC-3 rated current is 12A, and it can directly control a 5.5kW three-phase motor load at 400V.

S00 Compact Mechanism

The external dimensions are 45 (width) x 73 (depth) x 58 (height) mm, and it is mounted on a 35mm DIN rail, saving space in the distribution box.
