Motor protection and control REM630

REM630 has been designed to protect medium-sized and large asynchronous

and synchronous motors in the manufacturing and process industry.

Product highlights

• Motor protection both during motor start-up

and normal run, with protection and fault

clearance also in abnormal situations

• Extensive motor protection for medium-sized

and large asynchronous and synchronous

motors requiring differential protection

• Extensive motor supervision capabilities via

RTD and mA measurements

 The RTD and mA inputs can be

used for temperature measurement of motor

bearings and stator windings, thus extending

the functionality of the thermal overload

protection and preventing premature aging

of the motor windings. They can also be used

for measuring the ambient air or coolant

temperature. The four mA outputs can be used

for transferring freely selectable measured

or calculated analog values to devices provided

with mA inputs.
