Siemens 3RT1965-5AM32 Changeover Operating Mechanism for 3RT106 / 3RT146, 200-220 V AC/DC Original Brand New

Overview

The Siemens 3RT1965-5AM32 is a high-performance Changeover Operating Mechanism (Solenoid Coil) designed as a crucial spare part or accessory for SIRIUS 3RT1 Power Contactors, specifically the 3RT106 and 3RT146 series. This component is essential for the electrical operation and control of your contactor assembly.

It features a versatile AC (50/60 Hz) / DC operation capability, making it suitable for a wide range of industrial power control applications. The coil supports a control supply voltage of 200 to 220 Volts (AC/DC) and includes both standard and economy circuit operation for optimized performance and reduced power consumption. Its modern Spring-type terminal connection ensures fast, reliable, and vibration-proof wiring without the need for tools.

Key Benefits

• Universal Compatibility: Specifically designed for seamless integration with Siemens SIRIUS Power Contactors 3RT106 and 3RT146.
• Flexible Power Control: Supports both AC (200-220V, 50/60Hz) and DC (200-220V) control circuits, reducing inventory needs.
• Energy Efficiency: Features an economy circuit operating mechanism to minimize power draw during continuous operation (holding power).
• Reliable Connection: Spring-type terminals provide a quick, secure, and maintenance-free connection, highly resistant to shock and vibration.
• Genuine Siemens Part: Ensures optimal performance, long lifespan, and adherence to industry safety and quality standards.

Function & Application

The changeover operating mechanism, often referred to as the solenoid coil, is the electromechanical actuator of the contactor. When the specified control voltage (200-220V AC/DC) is applied, the coil generates a magnetic field that physically pulls the contactor’s main contacts into the closed (or open/changeover) position.

• Function: Actuates the main contacts of the 3RT106 and 3RT146 power contactors.
• Operating Voltage: 200…220 V AC (50/60 Hz) / DC.
• Terminal Type: Spring-type terminal for tool-free, robust wiring.
• Application: Used in motor control, industrial automation, HVAC systems, and any application requiring reliable high-current switching via a Siemens 3RT106 or 3RT146 contactor.
