Learn more by watching our Matelec FKW-15130-NMI | Bi-directional NMI Approved DIN Kilowatt Hour Meter video.
The Matelec FKW-15130-NMI is a single phase bi-directional kilowatt hour meter rated 100A at 230V AC for DIN rail mounting. The FKW-15130-NMI holds National Measurement Institute approval under NMI M 6-1 Part 1, certificate CoA NMI 14/2/126. Bi-directional measurement records energy flowing in both directions, which covers sites with solar generation exporting back through the same connection.
Sub-metering a granny flat, a tenancy or a workshop leaves the owner guessing at who used what. One revenue meter at the point of supply cannot separate a second dwelling from the main house, and estimated splits turn into arguments at invoice time. The FKW-15130-NMI logs consumption on its own circuit at Class 1 accuracy, and the NMI approval means those figures stand up when money changes hands.
The meter lands on standard DIN rail in a single module width, so it drops into an existing board without cutting a new enclosure. Sparkies fitting solar systems and tenant sub-boards get a backlit blue LCD a client can read in a dark meter box, plus 25mm2 terminals that take heavy cable straight off the isolator. One pole position covers the install, leaving board space for circuit protection.
The FKW-15130-NMI measures a single phase supply only and is not rated for three phase circuits. The IP51 housing is not weatherproof, so it must be mounted inside an enclosure and not in an exposed outdoor position. The operating temperature range runs from minus 20 degrees C to 65 degrees C.
Verified Sparky Direct customer reviews: Matelec FKW-15130-NMI Bi-directional NMI Approved DIN Kilowatt Hour Meter (FKW-15130-NMI)
"Great product and price" — Matt
(FKW-15130-NMI)
The Matelec FKW-15130-NMI carries National Measurement Institute approval, certificate CoA NMI 14/2/126 issued 27 August 2024, tested against NMI M 6-1 Part 1. That approval covers use of the meter readings for billing applications. Measurement accuracy is class 1.
Installation must be carried out by a licensed electrician. The FKW-15130-NMI clips onto standard DIN rail and takes one module position in a switchboard, meter box or sub-board. Current terminals accept conductors up to 25mm2 and the neutral terminal is rated to 2.5mm2.
Bi-directional means the meter records energy passing in both directions through the same connection. On a site with solar generation, that covers both the energy drawn from the supply and the energy exported back out, which is why the meter is listed as solar compatible.
Maximum rated current is 100A on a single phase supply, with an operational measuring range from 0.25A up to 100A. Overcurrent withstand is 1000A for 0.1 seconds. Nominal voltage is 230V AC at 50Hz to 60Hz.
The manufacturer warranty period is one year for domestic use and one year for commercial use, starting from the invoice date. The warranty method is return to Sparky Direct. Warranty is void where the product has not been installed by a licensed electrician.
No. The housing is rated IP51, which is dust protected and drip resistant only, so the meter must sit inside a suitable enclosure and not in an exposed outdoor position. It measures a single phase supply and is not rated for three phase circuits.
