The POK series plug-in relays (2-4-6-8-12 changeover contacts) are designed and built with materials and solutions that provide excellent endurance and robustness specifications.

Suitable for use in harsh working environments subject to severe thermal shocks.

Equipped with magnetic blow-out, these relays guarantee exceptional efficiency in the interruption of DC loads.

The common contact is mounted on a separate return device, comprising a flexible blade designed to ensure uniform pressure on the break contacts. The excellent electrical and mechanical performance of these relays allows them to be used in the most demanding mains, such as:

• Control and signalling functions in power stations
• Electrical transformer stations
• Rail transport
• Industries with continuous production processes.

Exceptional resistance to shocks and vibrations, ideal for use on rolling stock or in nuclear production. Compliance with standards
