Product Positioning

The 3RT2017-1BF41 is a model in the SIRIUS 3RT2 S00 miniature contactor family with a coil specification of 110V DC. It is commonly found in machine panels using 110V DC control power supplies or in modification projects requiring compatibility with existing 110V DC circuits. The main contacts maintain a 3-pole normally open design, with an AC-3 rated capacity of 12A and 5.5kW (400V), which can directly switch small three-phase motors. It is also equipped with a set of normally open auxiliary contacts for feedback or interlocking. All wiring uses screw terminals, which facilitates construction in the distribution box and subsequent maintenance and replacement.

Core Product Advantages and Features
110V DC coil
The coil has a rated voltage of 110V DC, making it suitable for existing 110V DC control panels or for directly using the original control power supply during machine modification.
AC-3 12A/5.5kW main contact
The 3-pole normally open main contact corresponds to a rated AC-3 motor of 5.5kW at 400V, suitable for direct starting and stopping of general small three-phase motors.
1 set of normally open auxiliary contacts
Built-in 1NO auxiliary contact can transmit the contactor's operating status, serving as an indicator light or a signal for higher-level monitoring.
S00 Compact Housing
Using the SIRIUS 3RT2 standard S00 frame, it is compact and easy to install in control boxes with limited space.
