MSR Contact protecting relays
Service intended: These relays provide higher contact rating of electromechanical contacts, increase the service life of contacts and avoid burning of oil in oil fi lled measuring equipment by means of pulse type control signals in the ratio of 1 : 100, minimizing the possibility of switching spark formation.
