Product Information
Full details
This ABB Energy Meter (A43 111-100) is designed for residential and small commercial users who need precise measurement of 3-phase energy consumption. Its key benefit is providing detailed electrical data including power factor, active energy, current, and voltage via an easy-to-read LCD screen. A potential caveat for some users is its single-tariff system and requirement for direct measurement setup.

FAQs
What type of electrical systems is this meter compatible with?
This meter is designed for 3-phase, 4-conductor systems.
What electrical parameters can be measured?
It measures power factor, active energy (W), current (A), and voltage (V).
How do I reset the meter or change settings?
Settings, including alarm configurations, are adjusted using the push-button located below the LCD display. For a full reset, power cycling may be an option, but refer to the specific product manual for detailed reset procedures.
What is the accuracy class of this meter?
The meter has an accuracy class of B.
Can this meter be used for billing purposes?
Yes, it is calibrated and approved under the Measuring Instruments Directive (MID), making it suitable for billing applications within its specified range.
What does the pulse output do?
The pulse output (S0 type) can be used to transmit energy consumption data to external devices like data loggers or Building Management Systems. It can also be configured as an alarm output.
What is the maximum current the meter can handle?
The meter has a maximum current rating of 80A.
Troubleshooting
Meter not displaying any readings
Verify that power is correctly supplied to the meter and that all 3-phase connections are secure. Check the circuit breaker or fuse for the circuit powering the meter.
Inaccurate energy readings
Confirm that the meter is correctly wired for direct measurement in a 4-conductor system. Ensure the nominal and maximum current ratings are not exceeded. Check for any loose connections.
Pulse output not functioning
Ensure the pulse output is correctly configured via the push-button interface. Verify that the connected device is compatible with the S0 pulse output standard and that its input is functioning correctly.
Alarm settings not saving
Ensure you are following the correct procedure for setting alarms using the push-button. Consult the product manual for specific instructions on saving configurations.
Pros and Cons
Pros
- Compact and space-saving DIN-rail mountable design.
- Clear digital display shows key electrical parameters.
- Easy-to-use interface with a single push-button.
- Versatile pulse/alarm output for data logging or system alerts.
- Meets accuracy standards with MID approval.
Cons
- Single-tariff system may not suit all billing needs.
- Requires direct measurement setup, limiting installation options.
- IP20 protection means it's not suitable for dusty or wet environments without further protection.
Setup, Compatibility & Care
Setup:
- Ensure the power supply to the meter is switched off.
- Mount the meter onto a standard DIN-rail using its integrated adapter. It occupies 7 modular spacings.
- Connect the four conductors for the 3-phase system to the appropriate terminals. Refer to the terminal markings for correct L1, L2, L3, and Neutral connections.
- Connect the pulse/alarm output terminals if required.
- Once wiring is confirmed, restore power.
- Use the push-button below the display to navigate the menu and configure alarm settings if needed.
Compatibility:
- Voltage: Compatible with nominal voltages of 57.7-288V (Line-to-Neutral) or 100-500V (Line-to-Line).
- Current: Designed for nominal current of 5A, with a maximum current rating of 80A.
- Frequency: Operates within a frequency range of 50-60Hz.
- Conductors: Suitable for 4-conductor systems.
- Output: S0 pulse output is compatible with standard energy monitoring systems.
Care:
- Keep the meter clean by wiping it with a dry or slightly damp cloth. Avoid using solvents or abrasive cleaners.
- Ensure the meter is installed in an environment within its specified operating conditions (avoid extreme temperatures, humidity, or dust). The IP20 rating indicates protection against solid objects larger than 12.5mm but no protection against water.
- Regularly check connections to ensure they are secure.
