Siemens SIRIUS 3RT2916-1PA3 EMC Interference Suppression Module, RC Element, 690V AC/DC, for 3RT201 Contactors Original Brand New

Overview

The Siemens 3RT2916-1PA3 is a high-performance EMC Interference Suppression Module designed specifically for use with Siemens SIRIUS 3RT201 series power contactors (Size S00). Utilizing an RC (Resistor-Capacitor) element, this module is crucial for suppressing voltage peaks that occur when the contactor coil is de-energized. It ensures the longevity of the contactor and protects sensitive electronic components in the control circuit from electromagnetic interference (EMI).

Function & Features

1. Surge Voltage Suppression: The primary function is to limit the high-energy voltage peaks (known as ‘blow-off’ or ‘turn-off’ voltage) generated by the inductive contactor coil when the control power is switched off.
2. EMC Interference Reduction: By suppressing these peaks, the module significantly reduces electromagnetic interference (EMI) that can disrupt adjacent electronic circuits, control systems (like PLCs), and sensor lines. This leads to increased system reliability.
3. Extended Contactor Lifespan: Protection of the contactor coil from excessive voltage stress contributes to a longer operational life for the contactor itself.
4. RC Element Technology: The RC element is particularly effective for AC control circuits and provides a balanced suppression characteristic.
5. Easy Installation (Accessory): The module is an auxiliary component that easily clips directly onto the compatible SIRIUS 3RT201 contactor, requiring no complex wiring or external enclosure space.

Benefit

• Maximum System Reliability: Minimizes electrical noise and voltage spikes, critical for maintaining stable operation in industrial automation environments.
• Protection for Sensitive Electronics: Safeguards PLCs, HMI, and other control equipment connected to the same network or cabinet from inductive feedback.
• Cost-Effective Solution: A small investment to prevent costly damage and downtime caused by high-voltage transients.
• Seamless Integration: Designed as an official accessory for the Siemens SIRIUS 3RT201 line, ensuring perfect fit and guaranteed performance.
• Broad Voltage Range: Suitable for a wide range of global control voltages up to 690 V AC/DC.
