The 24 V DC coil includes an integrated varistor for suppression, so you can skip the external RC snubber in most panels. The 1 NC auxiliary contact is wired into the control circuit from the factory — useful for feedback to a safety relay or PLC input without adding a side-mount block. Screw terminals on the S00 frame accept up to 4 mm² conductors, which is adequate for the 9 A motor circuit. The upright mounting position is the standard orientation for this frame; derating curves apply if you lay it flat or crowd multiple contactors side-by-side without a 10 mm air gap. Same part, different passport — the 3RT2016-1UB42-1AA0 ships from Siemens production globally without regional restrictions.","metaTitle":"Siemens 3RT2016-1UB42-1AA0 SIRIUS Power Contactor, 9A AC-3,","metaDescription":"Siemens SIRIUS 3RT2016-1UB42-1AA0 power contactor, AC-3e/AC-3 rated 9A, 4kW/400V, 3-pole, 24V DC coil with integrated varistor, 1NC auxiliary, screw terminals, size S00.
