Core Features
Comprehensive protection function: covering overload, short circuit, ground fault, locked rotor, current imbalance, underload, undervoltage/overvoltage, etc., quickly tripped through microprocessor algorithm (output relay action time is about 10ms).
Enhanced human-computer interaction: 40 character LCD screen+LED indicator lights+numeric keypad, supporting local fault diagnosis and parameter settings, equipped with a sealable pull-out handle to prevent misoperation.
Adaptation to harsh environments: The H code represents conformal coating, which can resist corrosion, hydrogen sulfide, and high humidity, and is suitable for harsh working conditions such as chemical and metallurgical industries.
Data monitoring and diagnosis: Real time monitoring of parameters such as current, voltage, power, temperature, etc., supporting event recording, statistics, and pre fault data tracing for easy maintenance and analysis.
Flexible integration and expansion: 4 analog outputs are easy to connect to DCS/PLC, 6 programmable relays are compatible with control logic such as soft start and interlock, and the communication interface supports remote monitoring and data upload.
Application scenarios
Protection and management of medium and large high-voltage three-phase asynchronous/synchronous motors in industries such as power, petrochemicals, metallurgy, and mining.
Motor circuit protection, control, and status monitoring of key rotating equipment such as compressors, fans, pump sets, and conveyor belts.
High reliability and resistance to harsh environments are required for motor systems, such as motor protection in offshore platforms and chemical corrosion areas.
