The 6 auxiliary contacts provide enough feedback and interlock capacity for most reversing applications without adding a separate auxiliary contact block. ## Mounting and wiring — DIN rail or screw, screw terminals throughout No special tooling needed for field wiring. Mechanical life is rated 10,000,000 operating cycles typical — a benchmark that aligns with SIRIUS contactors in conveyor and pump reversing duty where the reversing frequency stays under 750 operations per hour. ## Current production, quoted to order Lifecycle stage is current production — this reversing contactor assembly is an active catalog item, not a legacy or phased-out part.","metaTitle":"Siemens 3RA2316-8XB37-1CU0 SIRIUS Reversing Contactor","metaDescription":"Siemens 3RA2316-8XB37-1CU0 SIRIUS reversing contactor assembly, size S00, 4 kW at 400 V AC-3.
