The Terasaki K/93X/20-00IB is a dedicated communication module designed for seamless integration with Terasaki’s TemPower 2 series Air Circuit Breakers (ACBs). This module enables remote monitoring and control capabilities by utilizing the widely adopted Modbus RTU protocol over an RS-485 interface. It connects directly to the breaker’s Over-Current Relay (OCR), allowing for real-time data acquisition of critical electrical parameters, breaker status, and trip history. By integrating the K/93X/20-00IB, facility managers and engineers can incorporate their circuit protection devices into larger Building Management Systems (BMS) or SCADA networks, enhancing system visibility, operational efficiency, and predictive maintenance strategies.
