Siemens 3RT1936-1CC00 SIRIUS contactor RC surge absorber 48-127V

Product Positioning

The 3RT1936-1CC00 is an RC surge absorber suitable for Siemens SIRIUS large series S2 and S3 size contactors, corresponding to medium voltage coil circuits of AC 48 to 127V or DC 70 to 150V. The installation method is the same as other voltage versions in the same series, directly locked to the contactor coil terminals. It absorbs the induced surge during power failure through a combination of resistors and capacitors, protecting the PLC output module and relay contacts in the control circuit.

Core Product Advantages and Features

Medium voltage RC absorber

Designed specifically for AC48~127V and DC70~150V coil circuits

Installed on coil terminals

No additional wiring is required; simply lock it in place to use.

Protection control circuit

Reduce surge interference to PLC output points and relays

Voltage selection within the same series

This coil belongs to a different voltage range than 1CB00 and 1CD00. Please check the coil voltage before placing an order.

3RT1936-1CD00

The Siemens SIRIUS S2 and S3 size contactor uses an RC surge absorber, which is compatible with AC 127 to 240V or DC 150 to 240V coil circuits. It is installed on the contactor coil terminals and can reduce the interference and impact of surges on surrounding control components during power failure.

3RT1936-1CB00

The Siemens SIRIUS S2 and S3 size contactor RC surge absorber is designed for AC 24 to 48V or DC 24 to 70V low voltage coil circuits. It weighs approximately 0.027kg and is installed on the coil terminals to suppress power outage surges. The original manufacturer has discontinued production of this product, and the recommended replacement model is 3RT2936-1CB00.

3RT1935-6A
