The DER3B, differential relay with separate toroid our is a protective device that determines, by using actuators such as coils shunt or undervoltage release, the interruption of the power line if it detects a leakage current to ground type AC, AC pulsating or continuous higher than set threshold. They can be used on LV networks up to 1000V DC (with a pole to ground),...

The PFR RFX is capable of measuring: Power factor (PF), Voltage (TRMS), Current (TRMS), Active power, Reactive power, Temperature (through internal sensor NTC or external probe). It is capable of calculating: Weekly average value of PF (sliding window), Max voltage value, Capacitors overcurrent % and others, upon customer''s requirements. The adjustment of PF is carr...
