  • Fault loop impedance measurement with 0.01Ω resolution
  • Low-current impedance measurement in circuits protected by RCD ≥ 30mA with 0.01 Ω resolution (100…440 V)
  • Operates in networks with 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 (operating range 100…750 V)
  • Operating frequency 45…65 Hz
  • Calculation of fault current
  • Automatic differentiation between phase and phase-to-phase voltage
  • Possibility of applying 1.2, 5, 10, 20 m test leads or an adapter terminated by a power network plug
  • Measurement with swapped L and N conductors
  • Measurement of resistance (RS) and reactance (XS) components

Additionally features

  • Contact electrode – quick testing of proper connection of PE conductor.
  • Voltage measurement 0…750 V AC (0…250 V with resolution of 0,1 V).
  • Memory of 990 measurement results, ability to transfer the data to a PC via USB.
  • Power supply: batteries (4 x LR14) or rechargeable batteries.

Applications

This instrument is irreplaceable for all kind of electrical works, especially in situations where there is a need to check the circuits under voltage of 400/690 V. The meter is used for tests in homes, apartment blocks, public buildings, small workshops or factories and even at wind farms.

The meter is a perfect tool for testing systems, where fault currents may reach 5.3 kA (measured according to EN 61557).

The Sonel MZC-306 enables measurements in various types of networks including an approved version (Sonel MZC-306R) which holds full PADS approval with Network Rail for use on their 650V electrification network.  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 variant is fully PADS approved by Network Rail.

  • Network Rail approved for use by rail electrification engineers for testing PSCC on 650V signalling power feeders.
