It mounts stand-alone in any position and connects via spring-loaded terminals, accepting 2x (0.5... 2.5 mm²) solid or stranded wire. The thermal bimetallic release is temperature-compensated from -40... +60 °C, and the relay operates across -40... +70 °C ambient. If your application has a longer acceleration time (high-inertia loads like centrifuges or large flywheels), you'd typically step up to CLASS 20 or CLASS 30; this part is not for those. ## Auxiliary and tripped indication An integrated auxiliary switch provides a changeover contact for remote signaling. The relay carries a \"Tripped\" message indicator — a mechanical flag visible on the front face, so a walk-by check at the panel door tells you the relay has operated without needing a meter. Dimensions: 102 mm high, 45 mm wide, 79 mm deep. The spring-loaded terminals accept a 3 mm diameter screwdriver shaft (3.0 x 0.5 mm tip) for actuation. The relay complies with RoHS substance prohibitions effective 10/01/2009. MTTF under high-demand rate is 2,280 years. Storage and transport temperature range: -55... +80 °C.","metaTitle":"Siemens 3RU2116-0HC1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU2116-0HC1 SIRIUS thermal overload relay, CLASS 10, size S00, 690 V rated insulation voltage.
