It suppresses voltage spikes across the coil of AC/DC-operated contactors, protecting the control circuit from inductive kickback that would otherwise damage PLC outputs or relay contacts. ## Kit completeness check This is a single varistor module — no mounting bracket or hardware is needed; it clips onto the contactor's coil terminals. The kit is complete as shipped.","metaTitle":"Siemens 3RT5926-1BD00 SIRIUS Varistor Surge Suppressor","metaDescription":"Siemens 3RT5926-1BD00 SIRIUS varistor surge suppressor for contactor sizes S0 to S3.
