Siemens 3RT2016-1BB41 Three Phase AC Contactor

Siemens 3RT2016-1BB41 is a three-pole power contactor designed for AC-3e/AC-3 motor loads, rated to switch 9 A in the main circuit and to handle up to 4 kW at 400 V. It uses a 24 V DC coil and includes one normally open auxiliary contact for simple control wiring, with screw-terminal connections on both the main contacts and the auxiliary block in Siemens’ compact S00 frame size. The compact S00 form factor and 3-pole configuration provide straightforward line-side and load-side connections, making it a reliable choice for small industrial applications such as conveyors, pumps, and other equipment that requires robust phase switching in tight enclosures. In space-constrained panels, its compact footprint supports wiring simplicity and dependable operation for basic interlock or feedback tasks.
