Monitoring relays are used to protect people and machines and to control electrical cycles in line with the electrical or physicals parameters and, according to the low voltage directives certain individual applications have to be equipped with these relays.The range of products from METZ CONNECT offers a broad spectrum of measuring and monitoring relays suited for a multitude of applications: current monitors for universal applications, phase monitors as protection against destruction/deterioration of system parts, phase sequence relays to monitor the rotating field, asymmetric relays for a safe detection of phase failures, multifunctional 3-phase monitors, level relays for fill level monitoring
Thermistor relays are used for motor protection monitoring and to protect motors against thermal overload.
Level monitors are used for level or leakage monitoring of all conductive, non-flammable media.
Undervoltage monitoring relays are used in three-phase networks to monitor the general power supply for undervoltage.
Current / Voltage monitoring
Current / Voltage monitoring relays are used in live systems for monitoring direct or alternating/voltages/currents.
