Group Change-Over Switches Ex9BT3G are designed and intended for switching of auxiliary, control, measuring and switching networks. Tetsing according 60947-3 standard ensure functions na reliability for wide variety of applications. Utilization category AC-22A allows switching under load. They are available in variants with change-over contacts (CO) from 1 CO up to 4 CO. Contact form ( I-O-II ) allows a load to be manually changed from one electrical source to another, without risk of short-circuit.
