Product Positioning

The 3RT2016-1AD01 and 1AD02 in the same series are sister models with the same coil voltage but different auxiliary contact types. Both are 42V AC coil versions, the difference being that this model is equipped with one set of normally open auxiliary contacts, suitable for applications requiring signal feedback or indicator light circuits. The main circuit specifications are consistent with other 3RT2016 series models, AC-3 rated 9A, approximately 4kW at 400V. Kenxin Motors provides model inquiry and technical consultation services.

Core Product Advantages and Features

42V AC coil, safety compliant and user-friendly

The low-voltage coil design is suitable for production lines or equipment where safety regulations limit the control voltage.

Normally open auxiliary contacts have wide applications

One set of normally open (NO) contacts can be used for operation indication, PLC signal feedback, and other applications.

It is a sister model to 1AD02.

Different contact types for the same voltage allow for easy selection of NO or NC versions based on control logic.
