The assembly includes a varistor surge suppressor across the coil and an RS assembly kit (3RA2933-2C) for wiring the interlocking and timing circuits. The contactor size is S2, and the mechanical life is rated at 10 million operating cycles typical. ## Mounting and wiring constraints All terminals are screw-type — no spring-cage option on this variant. ## Protection coordination and environmental limits For Type 2 coordination, the required upstream fuse is 80 A gG (NH 3NA, DIAZED 5SB, or NEOZED 5SE).","metaTitle":"Siemens 3RA2434-8XF32-1NB3 SIRIUS Star-Delta Starter, 22 kW","metaDescription":"Siemens 3RA2434-8XF32-1NB3 SIRIUS contactor assembly for star-delta motor starting, rated 22 kW at 400 V.
