Siemens 3RT1016-1BB41 Three Phase Power Contactor

Siemens Sirius 3RT1016-1BB41 is a three‑pole power contactor in the compact S00 family designed for motor control in industrial panels. It uses a 24 V DC coil to switch AC loads and is rated for AC‑3 duty at 9 A, enabling control of motors up to roughly 4 kW at 400 V. The device features screw terminals in a space‑saving footprint and includes one normally open auxiliary contact for basic signaling or interlock tasks in control circuits. As part of the Sirius 3RT lineup, this unit shares standard mounting and wiring conventions with related models and is commonly used to start and stop three‑phase motors such as pumps, fans, or conveyors in compact automation panels. Siemens also lists a direct successor in the range, the 3RT2016‑1BB41, ensuring a path to newer stock while preserving the same general 3‑pole, 24 VDC coil, and 4 kW/400 V performance characteristics.
