The Sonel MZC-306 enables measurements in various types of networks up to 750V AC. The meter is invaluable for engineers who work on a variety of electrical work in low-voltage areas, such as solar, renewables, homes and buildings, public facilities, workshops and factories. The resolution of the measurement result is 0.01 Ω and the meter can also perform measurements in networks protected by RCD circuit breakers. The casing of the MZC-306 meter is IP54 rated, which provides a resistance to mechanical damage with the cover of the device also being able to be set at several positions to enable easy and comfortable transport and use of the meter.

The Sonel MZC-306R meter is fully Network Rail PADS approved under the Network Rail Certificate of Acceptance PA05/07453 and catalogue number 0092/010414. Approved for use in testing on the Network Rail 650V electrical system Signal Power feeders to test the fault loop impedance measurements. The Sonel MZC-306R measures Ik sometimes called PSCC (Prospective Short Circuit Current).

The MZC-310S is a professional portable meter for testing electrical installations with over-current circuit breakers. The instrument measures short circuit L-PE, L-N and L-L loop impedance and prospective short circuit loop current. Measurements can be done either with low measurement current (up to 42A) with 2-pole method or high measurement current (up to 280A) with 4-pole method that enables measurements with very high accuracy and resolution. The results can be stored in the internal memory and send to a computer via serial interface.

In the direct vicinity of transformers or in transformer stations, where the circuits are equipped with a high current protection (fuse-links with the rating of several hundred amperes, motor circuit breakers), fault currents may reach several hundreds of kilo-amps. Measurement of fault loop impedance in such networks requires a high-current meter, which is capable of measuring ZS values at the level of single milliohms.

The Sonel MZC-330S advanced high current meter is the right choice for professionals in the renewables wind power (690V), electrical, as well as installation and measurement industries. The device combines extensive measuring capabilities with high durability and resistance to harsh working conditions. A specially developed ventilation system translates into greater efficiency and significantly reduces working time.
