Product Positioning

The 3RT2017-1AP01 is a standard 3-pole AC contactor from the Siemens SIRIUS series S00 frame. It has an AC-3 rated current of 12A and can control a 5.5kW three-phase motor load at 400V. This model uses a 230V AC coil design, suitable for distribution panels or machines with a control circuit voltage of 230V. It has a built-in normally open (1NO) auxiliary contact for operation signal feedback. Both the main and auxiliary circuits use screw terminal wiring, making installation simple and maintenance and replacement easy. It is a common component in Taiwanese industrial distribution panels, water pump control boxes, and air conditioning systems. Kensun Motors is an authorized Siemens distributor, providing genuine products and complete selection consultation services.

Core Product Advantages and Features

230V AC coil design

The coil has a rated voltage of 230V and is universally compatible with 50/60Hz. It is suitable for existing power distribution systems with a control circuit voltage of 230V and can be used directly without the need for a transformer.

Built-in 1NO auxiliary contact

The main unit comes standard with one set of normally open auxiliary contacts, which can be used as a running indicator, PLC feedback signal, or interlock control, without the need for additional contact modules.

S00 miniaturization mechanism

With external dimensions of only 45 (W) x 73 (D) x 58 (H) mm, it can be installed on a 35mm standard DIN rail, making it suitable for applications with limited space in distribution boxes.

Highly durable design

With a mechanical life of 30 million operating cycles, a rated insulation voltage of 690V AC for the main contacts, and stable and reliable long-term operation.
