Description :
ARD series low-voltage motor protector
1 Product Introduction
Function:
This series of low-voltage motor protectors has protection functions such as overload, phase failure, imbalance, underload, grounding/leakage, and locked rotor. It can form a motor control and protection unit with electrical components such as contactors and motor starters, and has functions such as remote automatic control, on-site direct control, panel indication, signal alarm, and fieldbus communication.
Application scope:
It can be widely applied in the field of power distribution in industries such as coal mining, petrochemicals, smelting, electricity, and construction.
Ordering Example:
Specific model: ARD3T K1 A25/C+60L
Technical requirements: Electric motor power 5.5KW; DI is a passive node, controlling DO working voltage to 220V; LCD display.
Communication protocol: Dual RS485 interface Modbus/RTU protocol
Power supply: AC/DC220V
