Current clamp sensor 1/10/100/1000 A AC, switchable. Alternating currents from a few mA up to 1000 A Fault current measurements on three-wire cables High current measurements on conductors and rails with high accuracy. The Z3512A current clamp sensor is suitable for connection to digital multimeters with an input resistance of 5 -10 MW at V~. Due to its high measuring sensitivity, currents in earth loops can be detected and measured, as well as leakage or fault currents in the earthing of single-phase or three-phase networks. By switching to higher current ranges, it can also be used as a current sensor for high current applications with a very high transmission accuracy. The current sensor is used to extend alternating current measuring ranges. In conjunction with display and recording devices, alternating currents in cables and busbars can be measured without having to interrupt them. The secondary connection is made via permanently connected cables with touch-protected connector plugs. A protective circuit prevents the creation of high voltages if the secondary circuit is interrupted.
