Core Features
Comprehensive protection capability: covering overload, short circuit, ground fault, locked rotor, current imbalance, underload, undervoltage/overvoltage, etc. The microprocessor drives rapid tripping (about 10ms) to ensure motor safety.
Extended analog output: 8-channel 4-20mA output, capable of simultaneously uploading multi-dimensional data such as current, voltage, power, temperature, etc. to DCS/PLC, meeting complex monitoring requirements.
Convenient remote management: The Ethernet port on the back supports remote configuration, monitoring, and fault diagnosis, combined with EnerVista software to improve operation and maintenance efficiency.
Enhanced human-computer interaction: 40 character LCD screen+LED indicator lights+numeric keypad, supporting local parameter settings and fault tracing, with a pull-out handle to prevent misoperation.
Flexible control integration: 6 programmable relays adapted to control logic such as soft start and interlock, communication interface compatible with mainstream industrial protocols, and adaptable to various control system architectures.
Application scenarios
The protection and management of medium and large high-voltage three-phase asynchronous/synchronous motors in power, petrochemical, metallurgy, mining, etc., especially suitable for systems that require multiple analog monitoring.
The motor circuits of key equipment such as compressors, fans, and pump sets require remote monitoring and multi parameter uploading of operating conditions.
Motor protection in conventional industrial environments (without strong corrosion, high humidity), balancing cost and performance.
