Frequently Asked Questions - JKD250TMID HAGER

How do I install the Hager JKD250TMID meter?

Mount the meter on a 35 mm DIN rail in a suitable enclosure. Connect the phase and neutral wires as per the wiring diagram on the meter. Ensure the main power is off before installation.

What does the LCD display show?

The LCD shows total active energy consumption in kWh with 6+2 digits. A backlight is activated by pressing the button.

Is the JKD250TMID suitable for billing?

Yes, it is MID certified (Class B) and approved for use in sub-billing and allocation applications.

What is the accuracy of this meter?

It has accuracy Class B according to EN 50470-3, with a typical error of less than 1% at rated conditions.

How do I connect the pulse output?

The pulse output is an open-collector (SO) output, 4000 imp/kWh. Connect to a pulse counting device with a suitable pull-up resistor.

Can the meter be used for reactive energy?

No, the JKD250TMID measures only active energy (kWh). For reactive energy, a different model is required.

What is the maximum current rating?

The meter is rated for 5(65) A, meaning it operates on 5 A basis and can handle up to 65 A continuously.

How do I read the cumulative consumption?

The display automatically shows the total kWh consumption. Press the button briefly to toggle between displays if multiple registers are available.

Is the meter compatible with solar installations?

Yes, it can measure consumption from the grid. For net metering with generation, use two meters or a bidirectional model.

What maintenance does the meter require?

The meter is maintenance-free. If dust accumulates, clean the enclosure with a dry cloth. Do not use water or solvents.

Product Description

The HGR42EW series is part of the easywire ^® family of meters, designed to save up to 90% installation time compared to a standard meter and current transformer installation.

The meters contain two 3 Phase metering circuits in one case, and accept inputs from two separate easywire ^® 3 Phase current transformers while still utilizing the same voltage reference.

This MID approved, 4 module DIN rail mounted multifunction energy meter, is suitable for monitoring energy consumption and other electrical parameters in industrial and commercial applications. This series is particularly suited for use in split-load lighting and power boards, in three phase applications, and have been certified for billing purposes.

A high efficiency white backlit LCD display provides a clear indication of measured values in all light conditions. Front push-buttons allow user access to the display page required. The meter is available in two versions:-

• With two pulse outputs and RS485 Modbus communication.
• With two pulse outputs and Mbus communication
