Universal Motor Protection Relays (QPPLC24) are designed to directly monitor current using several different types of transducer elements. It’s an electronically controlled device used in motor applications to monitor/protect the motor from overload and short circuit current. It’s being used for many motor-related applications where real-time monitoring and protection are important to the motor’s operation.

QPPLC24 monitor the current flowing in the motor using current control algorithm where a magnetic pick-up sensor is installed in the motor line to detect the current. It monitors the motor current in real-time and provides a variety of protection functions to prevent motor damage due to overloads, short circuits, and other abnormal conditions. It comes with adjustable settings allowing the user to customize the overload and short circuit settings as needed.

The application field of QPPLC24 ranges from protecting HVAC systems, pumps, and other industrial motors to protect heavy-duty electric motors like those used in large machinery and commercial applications. It can also be used in industrial control systems to control the motor current and provide overload protection. Additionally, the QPPLC24 can be integrated with other motor control components to enhance motor protection and increase the efficiency of motor performance.

The working principle of a QPPLC24 relay is based on three functions; current monitoring, current protection, and current control. The current monitoring function detects the current flowing in the motor and if the current rises above the user-defined current setting, the protection will be triggered. This function also monitors the motor current in real-time and provides feedback on the motor condition. The current protection function trips the motor when the current surpasses the current limit value, preventing the motor from operating in an abnormal or dangerous condition. Finally, the current control feature can be set up to provide the motor with full-power operation by controlling the current flow.

Overall, the QPPLC24 relay provides accurate current monitoring and protection for motors in various sizes, makes, and models. It’s a reliable and cost effective solution for motor protection, and it can be integrated with other motor control components to improve overall motor efficiency. With its adjustable settings, it can be customized to suit the application and provide reliable and accurate current monitoring and protection.
