Description

WDB-1FMT Over Under Current Protection Relay Overload Motor Protection Relay Leakage Protector

The function of the motor protector is to provide comprehensive protection control for the motor. Overcurrent, undercurrent, phase failure, stall, short circuit, over voltage, under voltage, leakage, three-phase unbalance, overheating, grounding, bearing wear, When the rotor is eccentric, the winding is aged to give an alarm or protection control.

♦ Features

-- Separate structure,LED part panel mounted and CT part screw fixing

-- Built-in LED and keypad afford a precise,digital setting

-- Three-phase monitoring of short-circuit, locked-rotor,overcurrent, undercurrent, phase loss, phase unbalance,overvoltage,undervoltage

-- Earth fault (should couple with ZCT)

-- Fault recording

-- RS-485 communication port (optional)

-- 4-20 mA analog output (optional)

-- 2 C/O output contacts, one for trip,one for alert

♦ Protective Functions

-- Short-circuit

-- Locked-rotor

-- Overcurrent

-- Undercurrent

-- Phase loss

-- Phase unbalance

-- Overvoltage

-- Undervoltage

-- Earth fault

♦ Typical Applications

• Pumps • Fans

• Blowers • Motors

• Compressors
