Connection block for busbar. Three-phase busbar systems provide a simple, time-saving, and clearly organized way to supply 3RV2 motor starter protective devices with screw terminals. The system can be used with various types of motor starter protective devices up to 32 A. The three-phase busbar systems 3RV19 15 are generally not suitable for 3RV21 motor starter protective devices with overload relay function and for the 3RV27 and 3RV28 overload switches according to UL 489/CSA C22.2 No. 5–02. The busbars are suitable for 2 to 5 motor starter protective devices/overload switches. However, any type of extension is possible by connecting the terminal lugs of an additional busbar (rotated 180°) under the terminals of the respective last motor starter protective device. A combination of motor starter protective devices of different sizes is possible. The motor starter protective devices are powered through appropriate supply connection terminals.
