Its current-carrying capacity varies by control voltage: 2 A at 24 V, 2 A at 230 V, 1 A at 400 V, and 3 A at 120 V. For DC control circuits, it handles 0.3 A at 60 V and 0.22 A at 110 V or 125 V. At 220 V AC the rating is 0.11 A. These are the values for the tripped-signal contact, not the main power path — the relay itself does not switch motor current; it signals the contactor coil to open. ## Mounting and Wiring — S00 Footprint Fastening is via contactor mounting, meaning it snaps directly onto the contactor's rear face without additional DIN-rail space. The main circuit uses spring-loaded terminals accepting 2× (0.5 to 2.5 mm²) solid or stranded conductors. A 3 mm diameter screwdriver tip is specified for the auxiliary terminal screws.
