Siemens 3SR6112 Contactor

Siemens 3SR6112 Contactor is a three-pole switching device in the Siemens 3SR family, designed to control power to three-phase loads in industrial control panels. Typically used as the main switching element in motor starter assemblies, it enables remote or automatic on/off control of AC motors and other inductive loads when combined with compatible overload relays and auxiliary contacts. Because 3SR6112 represents a variant within the 3SR lineup, the exact coil voltage, current rating, and contact configuration depend on the installation, so the precise electrical characteristics should be verified on Siemens’ official literature or through an authorized distributor. In standard motor-control applications, it can be integrated into common control schemes such as star-delta or direct-on-line starting when paired with a complete starter assembly; verify the model’s suitability for your equipment by checking the manufacturer’s datasheets for applicable duty ratings and accessory options.
