It handles 127...240 V at 50 Hz and 240...127 V at 60 Hz, plus 150...250 V DC — so it covers both AC and DC control circuits common in mixed-voltage panels. The RC element snubs the inductive kick when the contactor drops out, which keeps transients off the PLC output or relay contacts driving the coil.","metaTitle":"Siemens 3RT1936-1CD00 SIRIUS Surge Suppressor, RC, 127-240V","metaDescription":"Siemens SIRIUS 3RT1936-1CD00 RC surge suppressor for S2/S3 contactors. 127-240V AC / 150-250V DC.
