Size S00 frame, 68 mm high, 90 mm wide, 145 mm deep. Screw and snap-on mounting onto 35 mm standard DIN rail. Clearance distances: 6 mm upwards, forwards, downwards, and to the side; zero clearance needed backwards. That 145 mm depth is the dimension to check against your enclosure depth — it's the full projection including the terminals. ## Motor ratings that decide the fit At 480 V it's 7.6 A; at 600 V it's 9 A; at 690 V it's 5.5 kW. AC-4 rating at 400 V is also 4 kW — that's the plugging/inching duty cycle, not just across-the-line start. If your application does frequent reversing under load, this is the rating to size against. Six auxiliary contacts total (instantaneous), three per direction of rotation. Coil terminals are screw-type; main circuit terminals are also screw-type. ## Environmental and compliance Operating temperature range -25 to +60 °C; storage -55 to +80 °C. Vibration resistance: 10.5g at 5 ms and 6.6g at 10 ms for both AC and DC excitation. RoHS compliance date 07/01/2006 — meets the EU substance prohibition. Mechanical life of the contactor typical: 10,000,000 operations. Coil rated at 110 V DC.","metaTitle":"Siemens 3RA2316-8XB37-1DF4 SIRIUS Reversing Contactor","metaDescription":"Siemens SIRIUS reversing contactor assembly, size S00, rated 4 kW at 400 V AC-3.
