Key Parameters Category Parameter Specification / Description General Model ABBMCB-01 Compatible Breakers ABB Emax 2 series air circuit breakers (ACBs) Primary Function Communication interface for monitoring and control Electrical Supply Voltage Typically powered directly from the breaker (auxiliary voltage), e.g., 24-250 V AC/DC. (Must be verified with the official datasheet for the specific version.) Power Consumption Low power, sourced from the breaker's auxiliary supply. Communication Primary Protocol Modbus RTU Physical Interface RS-485 (2-wire, half-duplex) Address Range Configurable Modbus slave address (typically 1-247) Baud Rate Configurable (e.g., 9600, 19200, 38400, 57600, 115200 bps) Parity Configurable (None, Even, Odd) Data & Functions Monitored Parameters Current (IL1, IL2, IL3, IN), Voltage (VLN, VLL), Power (kW, kVAR, kVA), Energy (kWh, kVARh), Frequency, Power Factor, etc. Status Information Breaker position (Open/Closed), Spring charging state, Ready to Close, Alarm/Trip status. Control Commands Remote OPEN, REMOTE CLOSE (subject to interlock and authorization). Protection Data Read (and sometimes set) protection thresholds, view trip logs and event history. Alarms System warnings, pre-alarms, and trip alarms. Mechanical & Environmental Mounting Direct plug-in or fixed mounting on the Emax 2 breaker. Operating Temperature -25°C to +70°C (typical for industrial environments) Standards & Approvals Complies with relevant IEC/EN standards for industrial equipment.
