Why Choose the ABB B24 113-100 Energy Meter?
The ABB B24 113-100 is a compact three-phase DIN-rail energy meter designed for transformer-connected measurement using external current transformers. Part of ABB's DIN Rail Mounted Meters range, it provides accurate active energy measurement for commercial, residential and industrial electrical installations where CT-connected metering is required.
Designed for 3 × 230/400 V AC three-phase systems, the B24 113-100 supports both three-wire and four-wire installations and provides Class B MID / Class 1 active-energy accuracy. Its transformer-connected design has a 1 A nominal current and 6 A maximum meter input, allowing the meter to monitor higher-current circuits through appropriately selected external current transformers.
Integrated M-Bus communication enables energy and instrumentation data to be accessed by compatible remote metering, building management and energy-monitoring systems. The meter also provides a configurable output for pulse or alarm functions, multiple instrumentation values, alarm monitoring and event logging, making it a flexible solution for centralised three-phase energy management.

Three-Phase CT Energy Monitoring with M-Bus
The ABB B24 113-100 uses external current transformers to provide three-phase active energy measurement on circuits where direct-connected metering is unsuitable. Its 1 A nominal current and 6 A maximum meter input support transformer-connected measurement, making the meter suitable for distribution boards, switchboards and other higher-current electrical installations.
Integrated M-Bus communication enables meter data to be incorporated into compatible automatic meter-reading, building management and energy-monitoring systems. Combined with multiple instrumentation values, a configurable pulse or alarm output, up to 25 alarm conditions and event logging, the B24 113-100 provides both local and centralised visibility of three-phase energy consumption.
