Siemens 3TH42 62-0AC2 Electromechanical Contactor

Siemens 3TH4262-0AC2 is an electromechanical contactor from the 3TH42 family with a 24 V AC coil (50/60 Hz) designed for use in control panels to manage auxiliary signaling within automation circuits. It incorporates six normally open (NO) and two normally closed (NC) auxiliary contacts (62E) on screw-terminal blocks for reliable wiring, and adheres to EN 50011, enabling standard control-relay applications. This 24 V AC coil version is suited for AC operation in 50/60 Hz environments and supports typical control functions such as sequencing, interlocking, and PLC I/O interfacing when paired with compatible Siemens contactors and control relays. The 3TH42 devices are compact, modular components intended to extend the control capabilities of larger power contactors or motor starters in industrial equipment, enabling compact multi-contact control within a single device.
