Monitoring relays
Monitoring relays supervise electrical and thermal quantities and trigger an alarm or switch off before a fault damages equipment. SCN supplies monitoring relays from TELE Haase: current monitors such as E3IM, V4IM and E3IF500, phase failure and phase sequence relays such as K3YM400 and V2PF480, as well as temperature and voltage monitoring relays. They protect motors, pumps, compressors, generators and installations against phase loss, overcurrent and undercurrent, overvoltage and undervoltage, and overheating. Our engineers help you choose the right monitoring function, measuring range, supply voltage and contact configuration for your application.
