3RT2017-1JB41

Like the 1JB42, it belongs to the PLC direct drive coil family. The difference is that it has one set of normally open auxiliary contacts, AC-3 12A/5.5kW/400V, operating range 0.7-1.25 times the rated voltage, net weight approximately 294g, and it cannot be fitted with an additional auxiliary contact socket.

Product Positioning

The 3RT2017-1JB41 shares the S00 frame and PLC direct-drive 24V DC coil design with its sibling, the 1JB42. Its operating range is 0.7 to 1.25 times the rated voltage, and the main circuit AC-3 rated at 12A/5.5kW (400V). This model has one normally open (NO) auxiliary contact, and no additional auxiliary contact modules can be added to the mechanism. It is suitable for motor start/stop circuits with PLC point-to-point control requiring only a single state feedback. Weighing approximately 294 grams, both the main circuit and control circuit feature screw terminals. Made in Germany, it allows for easy replacement of existing contactors in the same series.

Core Product Advantages and Features

PLC output direct drive design

The coil can be directly driven by the PLC digital output, reducing the time required for intermediate relays and wiring.

1 set of normally open auxiliary contacts

It can be used for operational status indication or to connect with a higher-level monitoring system.

Streamlining

This model cannot be fitted with auxiliary contact bases and is suitable for simple start-stop control applications.

Made in Germany

Adhering to the SIRIUS 3RT20 series S00 framework and quality standards, supply and spare parts are stable.
