Product Positioning

The 3RT2016-2AF04 belongs to the Siemens SIRIUS 3RT2016 S00 chassis series. The main circuit is 3-pole, AC-3 rated 9A, 4kW/400V, and the control coil voltage is 110V AC 50/60Hz (shared with the 110V coil specifications of the -1AF01 and -1AF02 series). It is suitable for applications where the electromechanical panel uses a 110V control power supply, such as some US standard or internal control circuits of machinery. The suffix "04" follows Siemens SIRIUS contact coding conventions, corresponding to a version with richer auxiliary contact combinations (commonly 2 sets of normally open + 2 sets of normally closed), which can simultaneously meet multiple applications such as indication, interlocking, and signal feedback. However, it is still recommended to confirm the actual auxiliary contact details with the manufacturer's catalog or sales personnel before placing an order. The terminal blocks feature a spring-loaded design, allowing for screwless quick crimping and significantly saving panel assembly time.

Core Product Advantages and Features

110V AC control coil

The coil is rated at 110V AC, 50/60Hz, suitable for machine tools and panels using 110V control circuit power supply. It has the same specifications as the AF series of letter rail coils, and has high compatibility in selection.

Spring-loaded quick-connect cable

Both the main circuit and auxiliary circuit use spring-clamped terminals, eliminating the need for screwdrivers and improving the efficiency of panel assembly, repair, and replacement.

Multi-auxiliary contact combination design

The last four digits 04 correspond to a number of auxiliary contact configurations according to Siemens contact code conventions, which can simultaneously support multiple control requirements such as interlocking circuits and operation indications.

SIRIUS Modular Platform

Inheriting the same mechanical life and safety performance as the SIRIUS 3RT2 series, it can be used with auxiliary contact modules, suppression modules and other accessories in the same series, offering high flexibility for expansion.
