Siemens 3RT1956‑1CE02 Surge Suppressor (RC Element) for SIRIUS 3RT1 S6/S10/S12, 240‑420 V AC Spring‑Type Terminal Original Brand New

Overview

The Siemens 3RT1956‑1CE02 is a high‑quality surge suppressor (RC element) designed for use with Siemens SIRIUS 3RT1 contactors—sizes S6, S10 and S12. Built with spring‑type terminals for secure and efficient installation, the device operates in an AC voltage range of 240 to 420 V.
By integrating seamlessly with the 3RT1 series, this accessory ensures that your control systems and contactor coils are protected from harmful transient over‑voltages, extending the lifetime of your equipment and fostering reliability in industrial environments.

Benefit

• Improved equipment longevity: Protecting your contactor coils and adjacent control electronics from voltage transients significantly reduces failure rates and extends usable lifetime of components.

• Reduced downtime & maintenance: By controlling over‑voltage events, you minimise unexpected equipment trips, coil burnouts or control faults—leading to better uptime.

• Simplified installation & service: Spring‑type terminals make wiring fast and dependable, reducing labour time and error risk during installation or servicing.

• Versatility across applications: The wide 240‑420 V AC range allows deployment in numerous industrial automation, motor control or control panel scenarios without needing multiple suppressor variants.

• OEM‑grade reliability: Backed by Siemens’ SIRIUS range, you get the assurance of a globally recognized brand and accessory matched to its original contactor family.

Application

This surge suppressor is ideal for installation on the coil or control side of SIRIUS 3RT1 contactors (sizes S6, S10, S12) used in motor starters, automation panels, switching systems and industrial control cabinets.
When the contactor is de‑energised, the collapsing magnetic field of the coil generates a voltage spike (back‑EMF). The RC element in this suppressor provides a low impedance path, clamping and dissipating that spike safely, thus protecting the rest of the circuit.
Choose the 3RT1956‑1CE02 when you have a 240‑420 V AC coil drive voltage and require a reliable, space‑efficient surge protection accessory with spring‑terminals.
