2CMA100184R1000 ABB B24 353-100 Three-Phase CT-Connected Energy Meter with M-Bus
ABB B24 353-100 is a three-phase CT-connected DIN-rail energy meter with Class C active energy accuracy, active and reactive import/export measurement, four-tariff capability and M-Bus communication.
The ABB B24 353-100 is an advanced three-phase current-transformer-connected electricity meter designed for accurate energy measurement in commercial and industrial electrical installations. As part of the ABB B24 EQ meter series, this Silver-function meter combines high-accuracy active and reactive energy measurement with multi-tariff functionality, configurable inputs and outputs, and integrated M-Bus communication.
Designed for indirect measurement through external current transformers, the B24 353-100 supports 1 A nominal and up to 6 A measurement current. It measures active and reactive energy in both import and export directions, with active energy accuracy to Class C (Class 0.5 S) and reactive energy accuracy to Class 2. The meter is suitable for 3-wire and 4-wire three-phase systems and is IEC approved as well as MID approved and verified.
With a system voltage of 3 × 230/400 V AC, up to four tariffs, two inputs, two outputs and integrated M-Bus communication, the B24 353-100 is well suited to sophisticated sub-metering and energy-management installations. Its compact four-module DIN-rail enclosure, backlit display, instrumentation values, alarm functions and event logging make it a versatile solution for monitoring electrical distribution systems.

Reliable CT-Connected Energy Monitoring
Current-transformer-connected meters such as the ABB B24 353-100 allow three-phase electrical systems to be monitored without routing the full load current through the energy meter. External current transformers provide a reduced measurement current to the meter, making this architecture suitable for higher-current distribution circuits while maintaining accurate measurement of active and reactive energy.
The B24 353-100 extends this functionality with bidirectional import/export measurement, multi-tariff registers, electrical instrumentation, alarms and event logging. Integrated M-Bus communication allows meter information to be collected remotely by compatible building-management and energy-management systems, providing a practical platform for detailed consumption analysis and sub-metering.
Typical Applications
Commercial building energy monitoring.
Industrial electrical distribution systems.
Three-phase CT-connected sub-metering.
Building management systems using M-Bus communication.
Factory and production-facility energy monitoring.
Tenant and departmental energy allocation.
Multi-tariff electricity monitoring.
Import and export energy measurement.
Distribution boards and switchgear assemblies.
Energy efficiency and electrical consumption analysis.
