The official successor is the 3RT2926-1ES00, with the preferred replacement being the 3RT2926-1ES00. This is a surge suppressor built with diode assemblies, designed for DC control supply voltages. It plugs onto the top of a SIRIUS size S0 contactor, suppressing the inductive kickback from the coil when de-energised. The voltage range covers 30 V DC up to 250 V DC, so it suits standard 24 V DC control circuits as well as higher-voltage DC rails found in some industrial panels.","metaTitle":"Siemens 3RT1926-1ES00 SIRIUS Surge Suppressor, 30-250 V DC","metaDescription":"Siemens SIRIUS 3RT1926-1ES00 surge suppressor with diode assemblies, 30-250 V DC.
