Schneider Electric – BCPMA224S (1B) – PowerLogic Branch-Circuit Power Monitor

The Schneider Electric BCPMA224S 1B is a branch-circuit power and energy monitoring unit from the PowerLogic BCPM Advanced series. Designed to measure power quality, voltage, current, and energy in multiple circuits, it features built-in 100 A solid-core CTs and supports Modbus RTU over RS‑485—ideal for use in power distribution panels and energy metering systems. The “1B” suffix typically denotes an alternate configuration or version of the base BCPMA224S; however, specific differences (e.g., CT secondary rating or communication enhancements) are not explicitly stated in publicly available documentation.
