MONITORING RELAY VOLTAGE 2CO 16A U24VUC

Monitoring relays protect expensive electrical equipment from damage caused by changes in electrical setpoints in the power network and from indirect effects of voltage fluctuations. For example, cold rooms are equipped with compressors driven by electric motors. These devices cannot withstand operational disturbances, as the refrigerant can return to the compressor during such events, causing damage to the cooling unit. A network monitoring relay can, in the event of a disturbance, simultaneously start a backup generator. Phase and current monitoring relays also protect loads during prolonged starting times or if the motor rotor becomes jammed, preventing potential damage from overload. Current limiting relays protect circuits from overload to optimize cables and connections. This product description is an automated translation of the original Finnish description.
