Solid-state contactors are far superior to mechanical contactors in terms of switching speed, service life, and robustness. Solid-state contactors work reliably and with stable switching times in dusty or chemically aggressive atmospheres. They switch resistive and inductive loads silently and without wear. The solid-state contactors in the CONTACTRON series are available for single- and three-phase networks and, depending on the type, also provide a reversing function.
