Current, Voltage and Phase Monitors Documentation   Product Selector

Carlo Gavazzi offers a comprehensive range of monitoring controls for monitoring of phase loss, incorrect phase sequence, phase unbalance, over/under current, over/under load, over/under frequency, and over/under voltage.

Our products include current monitors, voltage monitors, power monitors, phase loss relays, thermistor relays, and current transformers.

These monitors are used in a wide range of applications for protecting motors against the damaging effects of single phasing and overloads (elevators, compressors, pumps, air conditioning systems, mixing tanks). They are also used extensively for monitoring instrumentation signals (4-20mA, 0-10V), verification of machinery operation, detection of broken heater elements, monitoring of lights in critical areas (runway lights at airports), monitoring of ventilation fans, and in building automation systems

Our range of products also includes surge arresters for photo voltaic systems, standard current transformers (CTs), split-core current transformers, and CTs with analog output.
