The spring-loaded terminals on the main current circuit accept solid conductors 2x (0.5... 2.5 mm²) or stranded 0.5... 4 mm², making it a tool-less wiring choice for panel builders who want to reduce termination time on DIN-rail assemblies. For AC-4 duty (plugging, inching, reversing) at 400 V, the rating holds at 4 kW, meaning the contactor is sized for frequent jogging applications without derating the motor power. The auxiliary switch is built in, with contact ratings of 20... 12 for the auxiliary contacts — this covers the typical 24 V DC or 120 V AC control signals used in PLC-driven panels. The coil is DC-operated at 48 V rated value, with a pickup time of 7... 13 ms and arcing time of 10... 15 ms, which is fast enough for most sequencing applications but should be verified against the PLC scan cycle if the contactor is used in a safety-related interlock path. Power dissipation is 4.4 W at AC in the hot operating state — a useful number for enclosure thermal calculations when multiple contactors are ganged side-by-side. The 45 mm width and 70 mm height (73 mm depth) fit the S00 footprint, leaving clearance requirements of 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side. Side-by-side mounting is permitted, which is typical for multi-contactor motor starter assemblies in a panel. The contactor carries a RoHS compliance date of 10/01/2009, confirming it meets the EU Restriction of Hazardous Substances directive.","metaTitle":"Siemens 3RT2316-2BW40 SIRIUS Contactor, 4 kW AC-3, Spring Te","metaDescription":"Siemens 3RT2316-2BW40 SIRIUS contactor, size S00, 4 kW / 9 A at 400 V AC-3, spring-loaded terminals, 45 mm wide, current production.
