OKTF

OKTF series plug-in relays, created on the OK 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, factory set fixed delay time from 0.1s to 7s (external capacitor).

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.

Magnetic arc blow-out, ample contact clearance, exceptional efficiency in breaking DC loads and pulsed 5 kV insulation between open contacts.

Patented operating mechanism: mechanical life expectancy > 100,000,000 operations.

The contacts are mounted on individual and independent blades, deigned to assure unparalleled pressure values on the make and break contacts, in the region of 0.8…1N. Sliding and self-cleaning contact.
