3RT1926-1CC00

The 3RT1926-1CC00 is an RC absorption element for Siemens SIRIUS 3RT10 series S0 size contactors, rated at AC48-127V and DC70-150V. It is installed at both ends of the contactor coil to absorb the induced surge during power failure, protecting adjacent electronic control circuits. It is a common spare part for panel maintenance.

Siemens 3RT1926-1CC00 RC Surge Absorber

Product Positioning

In applications where contactors frequently switch, a back electromotive force surge is generated when the coil is de-energized. If not suppressed, this surge can easily interfere with nearby PLC input cards or electronic relays. The 3RT1926-1CC00 is an RC absorption element designed to address this problem. It is directly latched to the SIRIUS S0 size contactor coil terminal, and its compact size effectively reduces surge energy.

Core Product Advantages and Features

RC absorption principle

A combination of resistors and capacitors is used to absorb the induced surge when the coil is de-energized, thereby reducing electromagnetic interference to surrounding circuits.

Wide voltage range

Rated AC48-127V, DC70-150V, covering common control voltage ranges.

Easy to install

It snaps directly onto the SIRIUS S0 contactor coil terminals, requiring no additional wiring.

Lightweight

Weighing only about 0.013 kg, it takes up no space on the distribution panel.

Original factory authorized quality

Manufactured by Siemens and compliant with RoHS environmental directive

First choice for spare parts maintenance

Commonly used replacement parts suitable for maintenance of old machines

3RT1926-1CD00

The 3RT1926-1CD00 is an RC surge absorber specifically designed for Siemens SIRIUS 3RT10 series contactors. It consists of a resistor and a capacitor and is suitable for AC control voltages of 127 to 240V or DC control voltages of 150 to 250V. When installed on a contactor, it can suppress surge voltages during power outages. It is suitable for size S0 and is ideal for control circuits sensitive to electromagnetic interference.

3RT1926-1CB00

The 3RT1926-1CB00 is a low-voltage RC snubber element of the Siemens SIRIUS 3RT10 series S0 size contactor. It is rated for AC24-48V and DC24-70V and is suitable for 24V control circuit coil protection. It can be used with contactors with or without auxiliary contact modules and is a common spare part for control panels.

3RT1926-1BD00

The 3RT1926-1BD00 is a varistor-type surge absorber, rated at AC127-240V and DC150-250V. It is installed on the coil of SIRIUS 3RT10 series contactors of sizes S0 to S3, and uses the non-linear characteristics of the varistor to instantly clamp surge voltage. It has obtained international certifications such as CSA, UR, EAC, and RCM.
