★ It has multiple protection functions such as quick break, time limited quick break, overcurrent, overcurrent inverse time limit, overload, locked rotor protection, negative sequence overcurrent I and II sections, negative sequence II section inverse time limit, zero sequence overcurrent, overheating protection, overvoltage/undervoltage, PT disconnection/voltage loss, low-frequency load shedding, high frequency, bus grounding, system power loss, non electric quantity (over temperature trip, high temperature alarm), and has the function of recording protection events;
★ Comprehensive measurement of three-phase current, zero sequence current, three-phase/line voltage, active/reactive power, power factor, frequency, and other electrical quantities;
★ Energy metering: active energy (kWh), reactive energy (kvarh);
★ It has the function of judging the disconnection of the control circuit;
★ 1 RS-485 communication interface, Modbus RTU communication protocol, can remotely open and close circuit breakers;
★ 14 channel switch remote signal input: Among them, 8 channels have functions such as circuit breaker closing/opening, hot reset, remote control permission, manual tripping/closing, over temperature tripping, and high temperature alarm signal access;
★ 6-way relay output: used for accident signal, alarm signal, remote control opening and closing, fault tripping output, and locking motor start respectively;
Various comprehensive measurement values and SOE event records can be read in real-time through the communication port, and all protection parameters can be set through the display panel;
Scope of application: This motor protection and measurement device is suitable for asynchronous motor circuits with a capacity of less than 2000KW in systems with arc suppression coil grounding or ungrounded voltage levels of 10kV and 6kV.
