Description
Relais de surveillance EX9JP-4 400VAC 3 phases, 3 fils, protection des phases
•Les Atouts de l'article:
Monitoring relays Ex9JP are used to provide protection to circuits connected to the power grid These relayscan provide protection against overvoltage, undervoltage, unbalanced phases, phase sequence and phasefailure by analizing voltage on each phase. Temperature control by PTC thermistor in loaded device is optional.These monitoring relays are provided in various combination of protective functionalities with fi xed or adjustablevalues.Common application are power control systems, air conditioning systems and several motor applications.
