Measuring and monitoring relays

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

Fan timer

Fan timer

Fan timer relays are used for controlling two-level motors.


Speed monitoring

Speed monitoring

Speed and V-belt monitors are used to monitor rotary movements on motor-driven or belt-driven shafts.


CosPhi-monitoring

CosPhi-monitoring

CosPhi-monitors are used to detect underloads.


Motor protection

Motor protection

Thermistor relays are used for motor protection monitoring and to protect motors against thermal overload.


Level monitoring

Level monitoring

Level monitors are used for level or leakage monitoring of all conductive, non-flammable media.


Phase monitoring

Phase monitoring

Phase monitoring is used for monitoring important system parameters of a three-phase connection.


Undervoltage monitoring

Undervoltage monitoring

Undervoltage monitoring relays are used  in three-phase networks to monitor the general power supply for undervoltage.


Current / Voltage monitoring

Current / Voltage monitoring

Current / Voltage monitoring relays are used in live systems for monitoring direct or alternating/voltages/currents.


Current converter

Current converter

Current converter are used for the proportional conversion of large currents to directly measurable values.
