Product details

The Siemens 3RT6916-1CD00 is a SIRIUS surge suppressor built as an RC element, sized for S00 contactors and contactor relays. It clips onto the contactor coil terminals — no extra wiring, no DIN-rail space taken. That 9 mm depth means it stays flush with the contactor body, so panel layout stays tight. Voltage coverage: 127…240 V AC at 50/60 Hz and 150…250 V DC. AC/DC coil types are both handled — one SKU covers mixed-voltage panels. The RC element suppresses voltage spikes when the coil de-energizes, which protects nearby PLC outputs and extends contactor life.

Mounting and fit

Clip-on fastening to the contactor coil terminals — no screws, no tools. Dimensions: 28 mm wide, 46 mm high, 9 mm deep. That 9 mm depth is the key fit check: it matches the S00 contactor footprint, so the suppressor doesn't overhang the contactor body.

What is 3RT6916-1CD00's listed depth?

9 mm — it clips onto the S00 contactor coil terminals and stays flush with the contactor body, so it doesn't add panel depth.
