Sonel MZC-330S High-current Short-circuit Loop Impedance Meter

The Sonel MZC-330S high-current short-circuit loop impedance meter with efficient ventilation system for smooth and effective operation without downtime.

In case of multiple short-circuit loop impedance measurements, some measuring devices may get blocked. This problem does not affect the Sonel MZC-330S meter.

Sonel MZC-330S high-current short-circuit loop impedance meter comes complete with a calibration certificate traceable to National Standards.

Capabilities

• Measurement of very low short circuit loop impedances (with resolution 0.1 mΩ) with a current of 130 A at 230 V; maximum 300 A at 690 V. 
• Measurement with a current of 24 A at 230 V, maximum 37 A at 690 V with resolution 0.01 Ω.
• Measurements in installations with rated voltages: 110/190 V, 115/200 V, 127/220 V, 220/380 V, 230/400 V, 240/415 V, 290/500 V and 400/690 V and frequencies 45…65 Hz.
• Ability to perform measurements in short circuit system: phase-phase, phase-PE, phase-N.
• Differentiation between the phase voltage and the inter-phase voltage while calculating the short circuit current.
• Ability to change the length of test lead (measurement with 2p method).
• 4p (four-pole) method, test leads do not require calibration (measurement with current up to 300 A).
• Measurement of resistance (RS) and reactance (XS) components.

Additional features

• Touch voltage and touch shock voltage measurement with resistor 1 kΩ.
• AC voltage measurement in range 0…750 V.
• Frequency measurement 45.0...65.0 Hz.
• Memory of 990 measurement results, ability to transfer the data to a PC via USB and Bluetooth.
• Power supply: rechargeable battery
