SONEL-MZC-306 Short Circuit Loop Impedance

Lightweight, professional meter for short circuit loop impedance measurements Sonel MZC-306

Owing to a wide range of operating voltages, the professional meter Sonel MZC-306 enables measurements in various types of networks. The device is invaluable for a variety of electrical work in low-voltage areas, such as homes and buildings, public facilities, small workshops and small factories.

The resolution of the measurement result is 0.01 Ω - also when performing measurements in networks protected by RCD circuit breakers. The casing of the MZC-306 meter is made in IP54 protection degree, which ensures its resistance to mechanical damage. The cover of the device can be set in several positions, which enables easy and comfortable transport and use of the device.

Lightweight and professional fault loop meter
