The integration of four conducting paths to a reverse switch combined in one enclosure makes this device a particularly compact solution. Compared to conventional systems, for which two contactors are required, it is possible to save up to 50 % in width with the 3-phase reversing contactors. Devices with a width of 45 mm cover motors up to 2.2 kW – and those with a width of 90 mm cover motors up to 3 kW.¹⁾

¹⁾ In accordance with the product standard IEC 60947?4?2, the motor contactors are designed for motors with maximum starting current conditions of I/I_e ? 8. For configuring motors with higher starting current conditions (typically I/I_e ? 8) the data in the "SIRIUS 3RF34 Solid-State Switching Devices" manual must be taken into account.
