It clips onto the contactor — no tools, no extra DIN rail space — and suppresses voltage spikes across the coil. The RC element (resistor-capacitor) snubs both turn-off transients and conducted EMI, which keeps the control circuit clean and extends contactor life on inductive loads. Coil voltage range covers both AC and DC supplies: 127-240 V at 50/60 Hz, or 150-250 V DC. That dual-range flexibility means one part number works across panels with mixed control voltages — common in retrofit work where a 230 V AC coil contactor sits next to a 220 V DC solenoid valve. Physical footprint is minimal: 12 mm deep, 30 mm wide, 19 mm high. It mounts in any position and clips onto the contactor's coil terminals — no additional wiring or panel space consumed. RoHS compliance date is 05/01/2012 per the substance prohibitance listing. The part carries no explicit UL/CSA/CE marks in the record, but as a Siemens SIRIUS component it is designed for IEC/EN 60947-based panels common in European and export machinery. ## Panel integration Clip-on fastening to the contactor's coil terminals — no DIN rail slot needed. The 12 mm depth means it sits flush with the contactor face, not protruding into wiring channels. For an S0 contactor (45 mm wide), the 30 mm width of the suppressor leaves the contactor's auxiliary contact slots accessible.","metaTitle":"Siemens 3RT6926-1CD00 SIRIUS RC Surge Suppressor, 12 mm, 150","metaDescription":"Siemens 3RT6926-1CD00 SIRIUS RC surge suppressor for S0 contactors.
