Product name: General Electric Multilin 239-RTD-AN Motor protection relay

Product description
The GE 239-RTD-AN is a motor protection relay in the General Electric Multilin family. It is mainly used to protect the three-phase AC motor, by monitoring the motor current, temperature and other parameters, timely find and deal with overload, short circuit, grounding fault and other abnormal conditions, so as to protect the motor from damage, extend the motor service life.

Main function
Overload protection: By monitoring the motor current, when the current exceed

s the set value, the overload protection function is triggered.
Short circuit protection: monitor the motor winding short circuit, once a short circuit occurs, immediately cut off the power supply.
Ground fault protection: Detect the motor grounding fault to prevent equipment damage and personnel electric shock.
Temperature protection: Through the thermistor and other ways to monitor the motor temperature to prevent the motor from overheating.
