The Siemens 3RT1956-1CC00 is a surge suppressor accessory designed for 3-pole SIRIUS 3RT1 and 3RT2 contactors, specifically compatible with frame sizes S6 to S12. This accessory is used to suppress voltage spikes generated when the contactor coil is switched OFF, helping protect sensitive control equipment and improve system reliability.
When contactor coils are de-energized, transient overvoltages can occur within the control circuit. The 3RT1956-1CC00 surge suppressor effectively reduces these switching surges, minimizing electromagnetic interference (EMI) and protecting PLCs, relays, electronic controllers, timers, and other automation components from potential damage.
This accessory is widely used in industrial automation systems, motor control centers (MCCs), manufacturing plants, HVAC installations, process industries, and power distribution panels, where reliable contactor operation and protection of control circuits are essential.
As a genuine Siemens SIRIUS accessory, the surge suppressor ensures seamless integration with compatible contactors, easy installation, and long-term operational reliability.
