Siemens 3TH8253-0B Control Relay

Siemens 3TH8253-0B is a DC-coil control relay in the 3TH82 family, designed for control circuits in industrial automation. Catalog listings describe it as a DC-coil unit with eight fixed contacts, suitable for use in interlocking, sequencing, and logic switching within control panels. The -0B suffix corresponds to a maximum DC rating of 250 V for this family, with some retailer listings noting a 24 V DC coil for this exact model.
