ABB PM581 Product Overview

ABB PM581 motor protection relay is an intelligent protection device designed for motor protection.It integrates multiple protection functions,can monitor the running status of the motor in real time,and cut off the power supply in time when the motor is abnormal,so as to effectively prevent motor damage and fault expansion.

Product Features

Multi-function protection:It has multiple protection functions such as overload,underload,stall,short circuit,ground fault,etc.,providing comprehensive safety protection for the motor.

High-precision measurement:It adopts high-precision sensors and algorithms to accurately measure key parameters such as current and voltage of the motor to ensure the accuracy and reliability of the protection action.

Intelligent diagnosis:It has a fault self-diagnosis function,which can automatically detect and display the fault type,so that users can quickly locate and handle faults and improve maintenance efficiency.

Easy to operate:The friendly operation interface and intuitive indicator light design enable users to easily set parameters and view the motor status,reducing the difficulty of operation.

Installation and wiring

Installation location:Choose a dry,ventilated,dust-free,non-corrosive gas environment for installation,avoid direct sunlight and high temperature to ensure the normal operation and life of the protection relay.

Power wiring:According to the power specifications on the product label,use a suitable power cord to connect the protection relay to the power supply.When wiring,ensure that the specifications and wiring methods of the power cord meet the product requirements.

Motor wiring:Connect the current transformer or current line of the motor to the corresponding terminal of the protection relay to ensure that the wiring is correct.After the wiring is completed,it should be carefully checked to avoid wrong or reverse connection that may cause equipment damage or motor failure.

Setting and operation

Parameter setting:Set the rated current,protection threshold and other parameters of the motor through the operation interface to meet the protection requirements of different motors.The parameter setting should be accurate and reasonable to ensure the accuracy and reliability of the protection action.

Start and stop:Press the start button to start the protection relay,and press the stop button to stop the protection relay.During the start and stop process,pay attention to the indicator light and operating status of the protection relay to ensure the normal operation of the equipment.

Fault indication:When a motor fails,the protection relay will sound an audible and visual alarm and display the fault type on the operation interface.Users can handle faults according to the prompts and eliminate faults in time to ensure safe operation of the motor.
