It saves panel space versus wiring two separate contactors and avoids the risk of both coils pulling in simultaneously. The 24 VDC coil (spring-type terminals) pulls in reliably across the operating range of -25 to +60 °C, and the assembly manages 750 switching cycles per hour in AC-3 and AC-3e duty. ## Spring terminals and DIN-rail mounting — no screw torque to check No screw terminals to retorque after thermal cycling, which saves a step during panel commissioning and maintenance. Fastens onto 35 mm DIN rail with screw or snap-on mounting. Dimensions are 90 mm wide × 84 mm high × 83 mm deep (size S00 contactor frame). The required clearance around the assembly: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards — so it can sit flush against the back panel. This is not a surplus or obsolete part — it ships as a current-production Siemens assembly.","metaTitle":"Siemens 3RA2316-8XB30-2FB4 reversing contactor assembly","metaDescription":"Siemens SIRIUS reversing contactor assembly, 4 kW at 400 V AC-3, 690 V max.
