Product Positioning

The 3RT1926-1CD00 is an RC (resistive-capacitive) surge absorption accessory specifically designed for Siemens SIRIUS large contactors, suitable for S0 size contactors. When the contactor coil is de-energized, the RC element absorbs and suppresses the instantaneous surge voltage. Compared to diode-type suppressors, it is more suitable for AC control circuits and helps reduce the impact of electromagnetic interference on surrounding electronic equipment.

Core Product Advantages and Features

RC resistor-capacitor design

A combination of resistors and capacitors is used to absorb the surge voltage at the moment the coil is de-energized.

Wide-range control voltage compatibility

Applicable to AC 127 to 240V or DC 150 to 250V control circuits.

Suitable for suppressing electromagnetic interference

Compared to diode designs, it is more suitable for noise-sensitive control systems.

Applicable to S0 size

Designed specifically for Siemens SIRIUS S0 size contactors.

Installed on the contactor body

It can be installed directly on the contactor without requiring additional wiring space.
