Siemens SIRIUS 3RT1965-5XB42 Changeover Operating Mechanism for Contactor S10/S12, 24V DC Wide Range Coil, 24-110V DC, Spring-Type Terminal Original Brand New

Overview: High-Performance SIRIUS 3RT1 Contactor Accessory

The Siemens 3RT1965-5XB42 is a crucial accessory, specifically a changeover operating mechanism (also referred to as a solenoid coil or withdrawable coil) designed for the larger frame sizes of the SIRIUS 3RT1 Power Contactor series, particularly 3RT106 (S10) and 3RT146 (S12) models with the electronic operating mechanism suffix ...-0LA2.

This mechanism is engineered for reliable, high-performance switching in demanding industrial applications. It is part of the modular SIRIUS system, ensuring seamless integration and compatibility. The key feature of this model is its 24V DC wide-range operation and integrated PLC input capability, making it ideal for modern automated systems requiring direct control from a Programmable Logic Controller.

Function

The 3RT1965-5XB42 functions as the electromagnetic drive (coil) that controls the mechanical operation of the corresponding Siemens 3RT1 Contactor (3RT106 or 3RT146). When the specified 24V DC control voltage is applied, the mechanism is activated, closing the main contactor poles to switch the main power circuit (e.g., motor or resistive load). The integration of an electronic circuit with a dedicated PLC input allows the contactor to be controlled directly by modern automation systems with high-reliability signaling.
