SIRIUS 3RM1 motor starters are compact devices with a width of 22.5 mm, combining a large number of functions in a single enclosure. They consist of combinations of relay contacts, power semi-conductors (hybrid technology) and a solid state overload relay for operational switching of 3-phase motors up to 3 hp (at 480 V). For simple applications (such as starting and reversing 3-phase loads with overload protection), motor starter combinations of power contactors and a solid state overload relay, for example, can be replaced by a single 3RM1 starter. The more functions are required, the more devices can be replaced. The footprint area required for each motor starter in the control cabinet is reduced by values of 64 to 82%.
