Iskra MT172-P Direct Connected (Ofgem Approved)

The MT 172  is a direct connect operated 100A electronic kWh meter which is four-rate fully programmable. The large easy-to-read LCD display has automatic scroll with a press switch on the front for manual scroll, enabling you to see the many parameters available.

The large connection terminals and the small and compact design make it the ideal choice for all three phase four wire applications.

The MT 172 has an optional Optomos volt-free  pulse output relay which enables the meter to send pulses to an external management system and is compatible to the  Horizon Range of data loggers. The meter is fitted with short terminal cover as standard (H 190 mm)T.
