This suppressor clips directly onto the coil terminals of a SIRUS contactor of size S2 — no additional wiring or DIN-rail space needed. The clip-on fastening method and any mounting position let you install it without reorienting the contactor. Dimensions are compact: 30 mm wide, 30 mm high, and only 14.5 mm deep, so it adds negligible depth inside the enclosure.
