Product Positioning

The 3RT2017-1AN24 is a Siemens SIRIUS series S00 frame AC contactor. Its main circuit specifications are consistent with other contactors in the series, with an AC-3 rated current of 12A, capable of controlling a 5.5kW three-phase motor load at 400V. This model has a coil voltage of 220V AC and is equipped with 4 sets of auxiliary contacts (2NO + 2NC), providing more contact resources than standard single-auxiliary-contact models. It is suitable for automation control panels that require simultaneous output of operating signals, interlocking with other circuits, or feedback to a PLC. Both the main and auxiliary circuits feature screw terminal designs, allowing direct mounting on a 35mm standard DIN rail. Kenxin Motors is an authorized Siemens distributor and can assist in selecting the appropriate contactor model with the correct number of auxiliary contacts based on the site control logic.

Core Product Advantages and Features

220V AC coil

The coil has a rated voltage of 220V and is universally compatible with 50/60Hz, suitable for common 220V control circuit power supplies both domestically and internationally, and offers high installation compatibility.

2NO+2NC four sets of auxiliary contacts

It has three more sets of contacts than the standard single-contact model, which can simultaneously meet multiple control needs such as indication, interlocking and signal feedback.

S00 Compact Mechanism

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

Stable and durable

With a mechanical life of 30 million operating cycles and a rated insulation voltage of 690V AC, it is suitable for long-term continuous operation.
