Why Choose the ABB B24 111-100 Energy Meter?
The ABB B24 111-100 is a compact three-phase current-transformer-connected electricity meter designed for accurate measurement of active electrical energy in commercial and industrial installations. As part of the ABB B24 EQ meter series, it provides reliable energy monitoring where circuit currents are measured through external current transformers rather than by direct connection through the meter.
This meter is designed for CT-connected three-phase networks and provides pulse output functionality for transferring accumulated energy information to compatible monitoring, data-logging and building-management equipment. Its transformer-connected architecture makes it particularly suitable for higher-current distribution circuits where direct-connected DIN-rail meters are not appropriate.
The B24 111-100 combines ABB energy-metering technology with a compact DIN-rail format for straightforward installation in distribution boards and electrical control panels. Its digital display provides local energy readings, while the pulse output enables integration into wider energy-management and consumption-monitoring systems.

Reliable CT-Connected Energy Monitoring
Current-transformer-connected meters such as the ABB B24 111-100 measure electrical energy without requiring the full load current to pass directly through the meter. External current transformers reduce the measured current to a suitable secondary value, allowing energy consumption on higher-current three-phase circuits to be monitored safely and efficiently.
The pulse output allows accumulated energy data to be transmitted to compatible counters, controllers, data loggers or building-management equipment. This makes the B24 111-100 suitable for installations where local readings need to form part of a wider energy-management or sub-metering system.
Typical Applications
- Commercial building energy monitoring.
- Industrial electrical distribution systems.
- Three-phase CT-connected sub-metering.
- Distribution boards and switchgear assemblies.
- Factory and production-facility energy monitoring.
- Building management and energy-management systems.
- Departmental and tenant electricity consumption monitoring.
- Higher-current circuits requiring indirect energy measurement.
