Loop Testers

Loop testers are used to ensure that protective devices (fuses, circuit breakers etc) operate effectively proving that in a real electrical fault situation that protection devices operate correctly ensuring power is removed from the circuit quickly making for a no harm situation.
Sonel have a full range of short circuit loop impedance meters designed not to trip RCDs from standalone loop testers to loop testers combined with additional test functions and multifunction instruments that combine all necessary testers into one unit.
