Rating A 6 10 16 20 25 32 40 50 63 80 Disconnecting time 5s Disconnecting time 0. Loop impedance measurement is important in preventing accidents caused by the earth leakage breaker and other protection devices to becoming inoperative. Owned and operated by Prime Creative Media, Ferret.
Every circuit must be tested to make sure that the fault loop impedance does not exceed that specified for the over current protection device concerned. One of the khoritsu features of this model is the D-Lok circuit that permits loop impedance testing without tripping some types of RCD installed in the circuit being loop tested.
Custom microprocessor controlled for highest accuracy and reliability. We source consumer electronics, electrical engineering tools and other electronic products.
