Why Choose the ABB A43 313-100 Energy Meter?
The ABB A43 313-100 is an advanced three-phase direct-connected electricity meter designed for accurate energy monitoring in commercial, industrial and building-services installations. As part of the ABB A43 EQ meter series, this Silver-function meter combines direct measurement up to 80 A with active and reactive energy measurement, multi-tariff functionality and integrated M-Bus communication.
Designed for direct connection without external current transformers, the A43 313-100 can be used in 3-wire and 4-wire three-phase systems. It measures active and reactive energy in both import and export directions, with Class B (Class 1) active energy accuracy and Class 2 reactive energy accuracy. Separate energy registers and a resettable intermediate register support detailed analysis of electrical consumption and energy flow.
The meter operates across a wide 3 × 57.7/100–288/500 V AC measurement range and supports up to four tariffs. Two inputs and two outputs can be used for pulse, tariff and alarm functions, while integrated M-Bus communication, instrumentation values, configurable alarms and event logging provide comprehensive functionality for connected energy-management systems.
