Product Positioning

The 3RT2017-1BB41 is one of the most common 24V DC coil contactor models in the SIRIUS 3RT2 S00 frame series. It is widely used in motor start/stop circuits directly driven by PLC 24V DC outputs and is one of the most common specifications for control panels in Taiwanese machinery equipment. The 3-pole normally open main contact has a rated current of 12A and a rated power of 5.5kW at 400V AC-3. It also includes one set of normally open auxiliary contacts for status feedback. Wiring uses screw terminals and conforms to IEC 60947-4-1 standards. It can be used with S00 series auxiliary contact modules for expanded functionality.

Core Product Advantages and Features
24V DC coil standard
The coil is rated at 24V DC and can be directly driven by a PLC output point or a 24V control power supply. It is one of the most common specifications on production lines.
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 start-stop control of general small three-phase motors.
1 set of normally open auxiliary contacts
Built-in 1NO auxiliary contact provides operational status feedback signals, simplifying external monitoring wiring.
Modular expansion design
It can be equipped with SIRIUS 3RT2 series dedicated auxiliary contact base, mechanical interlock or suppression module to flexibly expand control functions.
