Description

OKT series plug-in relays, created on the POK platform, are designed and built with materials and solutions that impart excellent characteristics of endurance and ruggedness; suitable for use in harsh operating environments subject and when subject to strong thermal shocks.

Time delay on drop-out, switching time selectable from 0.1s to 60 minutes.  Switching time selector comprising 1 turn potentiometer. Switching time setting from 10 to 100% of full scale.

Equipped with magnetic arc blow-out, these relays guarantee exceptional efficiency in breaking DC loads. The common contact is mounted to a separate return device comprising a flexible blade designed to ensure uniformity of the pressure exerted on the break contacts.

The excellent electrical and mechanical performance of these relays allows them to be used in the most demanding sectors, such as control and signalling functions in electricity generating stations, electrical transformer stations, rail transport, or in industries with continuous production processes.

Exceptional shock and vibration resistance, ideal for use on rolling stock. High immunity to the electromagnetic interference typical of high voltage electricity distribution stations.
