The new SIRIUS 3RW5 soft starter design – with two integrated interfaces – encompasses 12 sizes with different power classes for controlling three-phase motors. In spite of the sizes and materials used, the devices create a harmonious atmosphere – and visually manifest their family traits. Front flaps hide all of the interfaces, while duct covers and recesses are used to cleanly route cables. By knocking out a precut front flap, customers can fit two different interfaces. The most essential elements for the users, such as LEDs and hinge covers, are located at the first level for user convenience.
