        Matelec | Bi-directional Kilowatt Hour Meter 100A 230V DIN Rail | NMI Approved Single Phase

        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.

        Features

        • NMI approved — certificate CoA NMI 14/2/126 issued 27 August 2024, tested against NMI M 6-1 Part 1 metrological and technical requirements for electricity meters.
        • Bi-directional measurement — records energy passing in both directions through the meter, which covers installations exporting solar generation back to the grid.
        • Class 1 accuracy — accuracy class 1 measurement, tight enough for billing arrangements between a landlord and a tenant.
        • 100A maximum rated current — the FKW-15130-NMI measures an operational current range of 0.25A through to 100A on a single phase supply.
        • Overcurrent withstand — the measuring circuit handles 1000A for 0.1 seconds, covering fault current passing through before upstream protection clears.
        • Backlit blue LCD — the digital display stays readable inside a dark meter box or a shaded switchboard cupboard without a torch.
        • Single module footprint — 90mm high, 18mm wide and 72mm deep, so the FKW-15130-NMI takes one pole position on the rail.
        • Fire resistant ABS housing — class 2 insulation construction in a moulded body specified for switchboard and meter box mounting.
        • 25mm2 cable capacity — the current terminals accept conductors up to 25mm2, with the neutral terminal rated to 2.5mm2.
        • Tamper seal kit supplied — sealing hardware ships in the box for installations where the meter is secured after commissioning.
        • Test output and indicators — a 1000 impulse per kWh test output, a mains power indicator, and a consumption indicator that flashes under load.
        • IP51 rating only — dust protected and drip resistant, so the meter belongs inside an enclosure and is not rated for exposed outdoor mounting.

        Where to use

        • Granny flats and secondary dwellings — the FKW-15130-NMI separates a second dwelling from the main house so consumption is measured rather than estimated.
        • Tenancy sub-metering — landlords recover electricity on evidence, with an approved meter reading behind each tenancy rather than a floor area split.
        • Solar and battery installations — bi-directional measurement suits systems where energy runs both ways through the same connection point.
        • Workshops and detached sheds — a sub-board feeding a workshop gets its own reading, useful where a hobby load or a business load sits on a domestic supply.
        • Rural outbuildings and pump sheds — measures a long sub-main run to a shed, bore pump or dairy from inside the sub-board enclosure.
        • Commercial tenancy fit-outs — the FKW-15130-NMI fits standard DIN rail in a tenancy distribution board during a fit-out or refurbishment.
        • High-draw appliance monitoring — puts a figure on a pool heater, a kiln, an EV charge point or a hot water circuit drawing under 100A.
        • Cost allocation on shared sites — multiple occupants on one supply each get an approved reading instead of a negotiated share.

        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.

        The Matelec FKW-15130-NMI is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
