Реле контролю 3P-3W: Регульований захист низької/високої напруги, фіксований захист незбалансованості з послідовністю фаз та виявленням обриву фаз з температурним захистом двигуна, Ex9JP-6P AC400V

Monitoring relays Ex9JP are used to provide protection to circuits connected to the power grid. These relays can provide protection against overvoltage, undervoltage, unbalanced phases, phase sequence and phase failure 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 adjustable values. Common application are power control systems, air conditioning systems and several motor applications.
