ОПИСАНИЕ ПРОДУКТА
SIEMENS 3TH2031-0HX4 - Control Relay
The SIEMENS SIRIUS 3TH20 series control relay is an electromechanical switching device engineered for auxiliary functions within industrial control circuits. It provides a contact configuration of three normally open (NO) and one normally closed (NC) auxiliary contacts, actuated by a 230V AC coil. This component is utilized in applications requiring reliable signal processing, interlocking, and control circuit expansion in motor control centers, automation systems, and general industrial machinery.
