The AC-4 rating is also 4 kW at 400 V, covering plugging and inching duty. The rated operational current at 400 V is 9 A. The impulse withstand voltage for the main circuit is 6 kV, and the auxiliary circuit shares the same 6 kV rating — both match typical panel coordination levels for 400 V distribution. Mechanical endurance is 30 million operations. DC switching delay (break time) is 7 to 13 ms. Width is 45 mm, depth 73 mm, height 58 mm. Side-by-side mounting is allowed. Terminals accept solid conductors 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²); stranded accepts 0.5 to 4 mm². An auxiliary switch is attachable. Relative humidity minimum is 10%. RoHS compliance date for substance prohibitance is October 1, 2009 — the part is RoHS-compliant. This is a current-production part. No end-of-life notice or successor has been issued.","metaTitle":"Siemens SIRIUS 3RT2316-1BF40 Contactor, 4 kW AC-3, 110 VDC C","metaDescription":"Siemens SIRIUS 3RT2316-1BF40 contactor, size S00. 4 kW AC-3 at 400 V, 110 VDC coil, screw terminals.
