Specifications
Wanlida Motor protection relays mainly applies to the low-voltage motor integrated controlling and protecting of AC 380V~1.2KV
Wanlida Low Voltage Motor Protection Relays Application Fields
The MMPR-230 motor protection relay works with external primary current transformer, mainly applies to the low-voltage motor integrated controlling and protecting of AC 380V~1.2KV. The products from this series can be used in petrochemical, hydro-electric power, thermal power, smelting and water pumping station.
Device features
- Uses high-performance 16-bit industrial microprocessors, high integration, functions strong, fast.
- Three phase current, voltage AC sampling, perfect measuring and controlling functions.
- Small size, under-power consumption, suitable for installation in the switchgear or on centralized panel.
- LCD display with wide temperature range.
- Strong anti-interference capability: Level IV of rapid transient interference, level IV of electrostatic discharge interference, electromagnetic interference III radiation level, pulse interference III-class group.
- With perfect protective function, automatic start functions when power restores. All kinds of reduction voltage start control modes, two-way and two-speed start control modes.
- Local start/stop switch and control mode selection switch.
- Remote start stop control with terminal control mode or communication control mode.
- Keeps records even power is off.
- 4~20mA output with Optical isolation.
- Equipped with Profibus and Modbus-RTU communication method, remote measuring, remote signal and remote control can be achieved through communication network and background monitor system.
