The Schneider Electric S48377 Modbus Cradle Communication Module (CCM) is a Modbus interface that plugs into the CCM cradle used with Square D MCCB systems, including FA/LA interfaces and Masterpact breakers. It is a 24 VDC powered device with a typical consumption of about 1 W and communicates over a 2‑wire Modbus RS‑485 network. Designed for Masterpact and Square D FA/LA MCCB installations, this CCM enables Modbus communications within electrical distribution setups, typically residing in the MCCB base CCM cradle to interface with a Modbus master.
