Siemens 3RT1016-1BB41 Contactor With Surge Suppressor

Siemens 3RT1016-1BB41 is a compact Sirius power contactor with three main poles and a 24 V DC coil, rated for AC-3 duty at 9 A with a 4 kW/400 V load, and sized in the S00 family for screw-terminal mounting. The unit includes one normally open auxiliary contact and, in this package, is paired with the 3RT1916-1DG00 surge suppressor module to damp coil transients and protect downstream control electronics. This 3-pole device is well-suited for switching small three-phase motors, pumps, and conveyors in automation panels and process equipment, and its screw-terminal S00 design supports straightforward panel installation. Belonging to the Siemens Sirius family, it offers compatibility within the Sirius/SIRIUS 3RT ecosystem and a clear cross-reference path to the newer 3RT2 series where applicable. Typical mechanical life is up to 30,000,000 switching cycles, with a 24 V DC coil ensuring reliable energization from common control circuits.
