Siemens 3RT1926-1CB00 RC Absorption Element

Product Positioning

Many small machine tools use a 24V low-voltage design for their control circuits, which can still generate surges when the coil switches. Without protection, this can accelerate the aging of contacts and electronic components. The 3RT1926-1CB00 is an RC absorption element designed for this voltage range. It is compact, quick to install, and compatible with both contactors with and without auxiliary contact modules.

Core Product Advantages and Features

Low voltage dedicated design

Rated AC24-48V, DC24-70V, corresponding to common requirements of 24V control systems.

Good compatibility

It can be used with contactors with or without auxiliary contact modules.

RC circuit absorbs surges

The combination of resistors and capacitors reduces electromagnetic interference when the coil is de-energized.

Quick installation

No wiring required, directly connects to the contactor coil terminals

Original factory quality guaranteed

Manufactured by Siemens and compliant with RoHS environmental standards.

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.

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.

3RT1926-1BC00

The 3RT1926-1BC00 is a varistor-type surge suppressor, rated at AC48-127V and DC70-150V. It is suitable for the coil protection of various SIRIUS 3RT10 size contactors, such as 3RT102, 3RT103, and 3RT104. It is a common spare part option for medium voltage control circuits and can be selected according to the existing contactor specifications.
