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.
Product Positioning
Unlike RC components, varistors absorb surges by utilizing voltage clamping characteristics to instantly absorb energy, resulting in a fast response and suitability for higher voltage control circuits. The 3RT1926-1BD00 is compatible with medium- and high-voltage control power supplies of AC127-240V and DC150-250V, and can be used with SIRIUS contactors of various sizes from S0 to S3.
