When the heat buildup exceeds the Class 10 trip curve, the relay opens its NC contact in the control loop, dropping out the contactor coil. The Size S00 frame limits the continuous current range this relay can handle; it's the smallest SIRIUS overload relay footprint, sized for contactors up to around 12 A rated operational current in AC-3 duty. The screw-type terminals on both main and auxiliary circuits accept 2x (0.5...1.5 mm²) solid or 2x (0.75...2.5 mm²) stranded, with AWG equivalents of 2x (20...16) and 2x (18...14). That's enough for the motor leads and control wiring on a small pump or fan. This relay is designed for contactor mounting — it snaps onto the bottom of a SIRIUS S00 contactor, forming a compact motor starter package on a DIN rail. Clearance requirements are tight: 0 mm upwards, forwards, backwards, and downwards, with only 6 mm needed at the side. That means it packs into a small enclosure without breathing room. The relay carries ATEX approval DMT 98 ATEX G 001 for use in potentially explosive gas atmospheres. It also meets RoHS substance prohibitance dated July 1, 2006. Surge voltage resistance is rated at 6 kV, and the relay withstands 8g shock for 10 ms — enough for industrial panel vibration.","metaTitle":"Siemens 3RU1116-1BB0-ZW96 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1116-1BB0-ZW96 SIRIUS thermal overload relay, Size S00, Class 10 trip, 3-pole, screw terminals, ATEX approved.
