contact protection relay MSR 011 Interval | 38203
contact protection relay MSR for electrical contact
manufactured goods
Controlling the electromechanical contacts with pulse-shaped voltage avoids unwanted switching. This protects the contacts and prolongs their service life due to a dropout delay. Specially recommended for liquid-filled measuring instruments.
