It mounts directly onto 3RT10 contactors in sizes S00 and S0, and onto 3RH contactor relays with DC operation, using the same screw and snap-on mounting onto 35 mm standard DIN rail per EN 50022. Control voltage is 110-127 V AC/DC, meaning it accepts either AC or DC supply across that range — useful when the control circuit is mixed or being migrated. Rated for operation from -20 to +60 °C and storage from -40 to +80 °C, so it handles the thermal range inside a standard IP20 control cabinet without derating concerns. ## Panel integration and fit Mounts directly onto the contactor's front face — no additional DIN rail space required. The snap-on mechanism engages with the contactor housing; screw terminals are then wired per the control schematic. The finger-safe design means no additional shrouding is needed for the terminals inside an IP20 enclosure.","metaTitle":"Siemens 3RT1916-2BK01 OFF Delay Device, 110-127V AC/DC, S00/","metaDescription":"Siemens SIRIUS 3RT1916-2BK01 OFF delay device for contactors. 110-127V AC/DC control voltage, fits S00/S0 sizes.
