Sonel MPI-506 Multifunction Tester - CAT IV

Multifunction Tester for Commissioning and Periodic Testing of Electrical Installations

Primary Functions

Measurement of short circuit loop parameters

High Current Measurement of  Loop Impedance. L-L, L-N, L-PE. Voltage range: 180-460 V.           
Maximum test current: 7.6 A (at 230 V), 13.3 A (at 400 V)
Display of Short Circuit Loop Resistance R, Short Circuit Loop Reactance X, and Prospective Short circuit Current
Non Trip Low Current Measurement of  Loop Impedance. L-PE using 15 mA current, to avoid tripping the RCD 

Testing of RCD Breakers Type AC & A

Testing of prompt, short-delay and selective RCDs with rated current values 10, 15, 30, 100, 300, 500 mA
Measurement of IA trip current and tripping time tA for currents 0.5 IΔn, 1 IΔn, 2 IΔn, 5 IΔn 
RE and UB measurement without RCD tripping
Extended AUTO function of RCD measurement, with the possibility of measuring ZL-PE with low current
