Siemens 3RU1116-1HC1 Industrial Control Relay Module

Siemens 3RU1116-1HC1 is a Sirius thermal overload relay (size S00) for motor protection, featuring a 5.5–8 A setting range, a 1NO+1NC contact configuration, and a Class 10 thermal rating. It is designed for stand-alone installation or mounting with compatible Siemens 3RT contactors, such as 3RT1015/1016/1017, and uses cage-clamp connections for secure terminations. The device supports insulation voltage up to 690 V and is part of the Sirius Classic line, with a 3-phase motor protection configuration up to roughly 3 kW depending on voltage and motor type. The compact S00 footprint makes it well suited for motor protection in small control cabinets.
