3RT2017-1VB41

Like the 1VB42, it belongs to the electronic wide-range coil family. The difference is that the auxiliary contacts are changed to one set of normally open (NO). It is an AC-3 12A/5.5kW/400V, 24V DC coil that can withstand voltage fluctuations of 0.85-1.85 times, suitable for general starting circuits.

Product Positioning

The 3RT2017-1VB41 shares the S00 frame and 24V DC electronic wide-range coil design with its sibling, the 1VB42. The main circuit has an AC-3 rated voltage of 12A/5.5kW (400V), and the coil can operate stably within a range of 0.85 to 1.85 times the rated voltage, absorbing voltage fluctuations in the control power supply better than traditional DC coils. This model features one normally open (NO) auxiliary contact, suitable for status indication, interlock start signals, or counting circuits. It is compatible with original screw terminals and DIN rail mounting, facilitating standardized configuration and subsequent maintenance of distribution panels.

Core Product Advantages and Features

Wide-range electronic coil

The 24V DC coil has an operating range of 0.85 to 1.85 times the rated voltage, making it suitable for production line environments where the control power supply voltage is unstable.

1 set of normally open auxiliary contacts

It has a built-in 1NO auxiliary contact, which can be used as a start-up status feedback or interlocked with other control elements.

Shared frame with S00 series

The external dimensions and mounting hole spacing are the same as the 3RT2015/2016/2017 series, which facilitates spare parts management.

Screw terminal design

Both the main circuit and the control circuit use screw terminals, which can connect to 0.5-4mm² wires, making on-site wiring familiarity high.
