It switches the control signal to the contactor coil, so the 3 A ceiling covers most 24-240 V AC/DC contactor coils in the SIRIUS family without derating. The adjustable time range spans 0.05 to 100 s, set via a front-panel potentiometer or DIP switch depending on the variant. Recovery time between cycles is 150 ms — the timer resets fast enough for sequential start applications on conveyor or pump banks. The pickup threshold is 85 % of rated voltage, so it drops out cleanly on a sagging line. ## DIN-rail footprint and environmental limits Depth is 74 mm, height 38 mm; mounting position is any, like a contactor, meaning it can be installed horizontally or vertically in a crowded panel. Pollution degree 3 means it tolerates conductive dust and condensation typical of industrial control cabinets not hermetically sealed.","metaTitle":"Siemens 3RA2813-1AW10 SIRIUS ON-Delay Timer, 3 A","metaDescription":"Siemens 3RA2813-1AW10 SIRIUS ON-delay timer relay, 3 A max, adjustable 0.05-100 s, 24-240 V AC/DC.
