Solid-State Switching Devices for Switching Motors Solid-State Contactors 3RF24 solid-state reversing contactors, three-phase 1) The reduced values in brackets apply to a directly mounted circuit brea- ker and simultaneous butt-mounting. 2) To reduce the risk of a phase short circuit due to overvoltage, we recom- mend using a varistor type 3TX7 462-3L between the phases L1 and L3 and as close as possible to the switchgear. We recommend a design with semiconductor protection as short-circuit protection. 62 Siemens · 2009 Order No. Fuseless design with motor starter protector CLASS 10 Rated operational current IAC-531) Power loss at Short-circuit protection with type of coordination "1" acc.
