The mechanical interlock is built into the assembly; the two contactors share a common base and the interlock prevents both coils from pulling in simultaneously, which would short the supply phases through the motor windings. ## Mounting and panel integration — DIN rail with rotation flexibility Clearance distances are tight: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards — meaning the assembly can sit flush against the backplane without additional air gap. ## Termination and wiring — screw-type terminals, dual conductor entry Both the main current circuit and the magnet coil use screw-type terminals — no spring-cage tooling required, which simplifies field replacement on existing panels wired with ring or fork lugs. Four instantaneous auxiliary contacts are built in, with two per direction of rotation — enough for a local run indicator and a remote status signal without adding a separate auxiliary contact block. ## Environmental and mechanical endurance Rated for 10 million mechanical operating cycles typical — the contactor assembly outlasts the driven equipment in most reversing applications, provided the electrical switching frequency stays within the AC-3 or AC-4 duty limits. Shock resistance is 10.5 g for 5 ms and 6.6 g for 10 ms on both AC and DC supplies — the assembly holds its contact position under vibration from adjacent contactors or motor starters on the same rail. ## Sourcing and lifecycle — current production, quoted to order RoHS compliance is documented with a substance prohibitance date of July 1, 2006 — the assembly meets the EU RoHS directive for lead, mercury, cadmium, and other restricted substances.","metaTitle":"Siemens 3RA2316-8XB34-1CU0 Reversing Contactor, S00","metaDescription":"Siemens SIRIUS 3RA2316-8XB34-1CU0 reversing contactor assembly, size S00, rated 4 kW at 400 V AC-3.
