It connects to current transformers up to 5000 A primary and communicates measured values in real time via Modbus RTU over RS485 — making it well suited to switchboard builders, BMS integrators, and energy management applications where reliable sub-metering data is required. The built-in LCD display provides direct local readout of all key parameters without the need for an external tool or gateway.\u003c\/p\u003e\u003ctable
