3RT2016-1BA41
The Siemens SIRIUS S00 series power contactor features a 12V DC coil with one set of normally open auxiliary contacts. The main contact AC-3 is rated at 9A/4kW/400V and is suitable for low-voltage DC control circuits and simplified distribution box designs.
Product Positioning
The Siemens SIRIUS 3RT2016-1BA41 is a rare 12V DC coil version in the S00 size three-pole power contactor family. It is designed for low-voltage DC control circuits (such as battery-powered, off-grid solar systems, or control boxes requiring step-down protection). The main contact AC-3 is rated at 9A and can directly start and stop a 400V/4kW three-phase motor load. It also has a built-in normally open (1NO) auxiliary contact for status feedback or interlocking.
Core Product Advantages and Features
12V DC coil design
Compared to the common 24V/230V coil versions, the 1BA41 uses a 12V DC operating voltage, making it suitable for driving the coil with low-voltage DC power supplies (such as automotive batteries, off-grid solar systems, or control boxes requiring step-down protection), reducing the need for additional transformers and voltage regulators.
AC-3 9A/4kW main contacts
The three-pole main contacts can directly control a 400V/4kW three-phase induction motor load, conforming to the AC-3 usage category of IEC 60947-4-1 standard, and are suitable for applications such as direct motor start and forward/reverse combination.
1 set of normally open auxiliary contacts
The device has a built-in 1NO instantaneous auxiliary contact, which can feed back the contactor's operating status to the PLC or control circuit, making it easy to form interlocking and indicator light circuits.
S00 size, screw terminals, made in Germany.
Adopting the SIRIUS universal S00 form factor, the screw terminal wiring allows for quick installation. The product is made in Germany and complies with environmental regulations such as RoHS and WEEE.
