Auxiliary contactor AC coil 24 V AC coil-3TH5031-0AB0

Product Description

Auxiliary Contactor, AC Coil 24 V AC – 3TH5031-0AB0

The Siemens 3TH5031-0AB0 is a compact and reliable auxiliary contactor (contactor relay) designed for use in control, signaling, and interlocking circuits of industrial automation systems. It is used to provide multiple auxiliary contacts for logic control, feedback signaling, and switching operations in electrical control panels.

This model is part of the Siemens 3TH5 series contactor relays, engineered for high reliability and long electrical life in low-power control applications. It operates with a 24 V AC control coil, making it suitable for PLC-controlled systems, machine automation, and industrial control circuits where safe and efficient signal switching is required.

The 3TH5031-0AB0 typically offers multiple auxiliary contact combinations (such as NO/NC configurations), allowing flexible wiring for control logic, status indication, and interlocking functions in LT panels, MCCs, PCCs, and OEM machinery.
