Self-assembly, never easier!
Apart from the pre-assembled devices, contactor assemblies can also be created by the user. In sizes S00, S0 and S2, there is a special feature that makes assembly possible almost without the need for wiring: Using the appropriate, plug-in function modules for fitting to contactors which include timer functions or even electrical interlocks, reversing assemblies or star-delta (wye-delta) assemblies, for example, can be implemented quickly and easily - without the need for additional control wiring, protective circuit or prioritization circuit. Apart from the pre-assembled assemblies, contactor assemblies can also be created by the user from individual devices. In combination with the contactors of the new 3RT2 series, this is particularly easy: Whereas, for the main circuit, wiring kits are available for both screw-type terminal and spring-loaded terminal devices, function modules that can be plugged into the contactors revolutionize the control circuit: In this manner, timer functions, direct, reversing and star-delta (wye-delta) starter functions are configured quickly and easily without the need for tools - without any additional control wiring or protective circuit because the contactors are already included.
