Eighteen millimetres, forty amps, and a pulse output.

One module

18 mm on a standard DIN rail. That is the narrowest meter in this family and it matters more than it sounds: a consumer unit that is already full has one module of space, not four.

The pulse output

S0, 2000 pulses per kilowatt-hour. The rate is published, which is what a logger needs to turn counting into kilowatt-hours. It is the oldest and simplest way to get a meter into software, and it works with anything that can count a contact closure.

The standard

IEC 62053-21, named. That is the right standard for a static energy meter, and five of the eleven meters in this catalogue name one at all.

What it does not say is which class within it — 1 or 2 — which is the figure that would put a number on the accuracy.

The rest

40 A direct, single phase at 230 V, a 6+1 digit LCD, IP51. Dripping water rather than splashing, which suits a consumer unit and not an outdoor one.

    Amazon reference
    B083GYP8JS (same reference on 6 Amazon marketplaces)
    EAN
    0795787227480
    • Two dimensional standards cited — DIN EN 50022 for the rail and DIN 43880 for the module width
    • The reading survives a power cut and cannot be reset, which is what a billing sub-meter needs
    • No accuracy class

    Best for: A sub-meter whose reading has to be trusted over years rather than watched daily.

    • No accuracy class and no MID approval, at a price close to the two meters that have it

    Best for: Working out what a circuit actually uses, day by day, before deciding anything.
