Schneider P3M32 Motor Protection Relay

• Overload Protection: It can monitor the motor current in real-time. When the current exceeds the set overload threshold, it acts according to the preset inverse time characteristic to prevent the motor from being damaged due to long-term overload operation.
• Short-Circuit Protection: It can quickly detect short-circuit faults in the motor circuit, instantly trigger protection actions, cut off the circuit, and prevent short-circuit current from causing serious damage to equipment.
• Ground Fault Protection: It monitors ground faults of the motor. When a ground fault occurs, it timely sends out alarm signals or trip commands to ensure the safety of personnel and equipment.
• Undervoltage Protection: When the power supply voltage is lower than the set value, the protection relay acts to prevent the motor from running in an undervoltage state, avoiding damage to the motor due to insufficient torque and stalling.
• Overheating Protection: It monitors the motor temperature through a built-in temperature sensor or an external temperature probe. When the temperature exceeds the safe range, it takes corresponding protection measures such as alarming or tripping.
• Arc Protection: It has an arc detection function. When an arc short-circuit in the motor or connected lines is detected, it acts quickly to reduce the harm of arc faults to equipment and personnel.

• Digital Input and Output: It provides multiple digital input channels, which can receive external control signals such as breaker opening and closing signals, remote control signals, etc. It also has multiple digital output channels for controlling the actions of breakers, contactors, and other equipment.
• Matrix Control: It supports the matrix control function, which can realize complex control of multiple devices according to user-set logical relationships, meeting the needs of different application scenarios.

• Current and Voltage Measurement: It can measure the three-phase current and voltage values of the motor circuit in real-time, providing users with accurate electrical parameter information for operation monitoring and fault analysis.
• Power Measurement: It can calculate and display the active power, reactive power, and apparent power of the motor, helping users understand the power consumption of the motor and realize energy-saving management.
• Power Quality Monitoring: It analyzes the harmonic content of voltage and current, monitors power quality, timely detects harmonic problems in the power system, and avoids the impact of harmonics on the motor and other equipment.

• User-Friendly Human-Machine Interaction:
  • Graphical LCD Display: Equipped with a high-resolution graphical LCD display, it can clearly show various measurement data, operation status information, alarm information, etc., and can display single-line diagrams, facilitating users to intuitively understand the system operation status.
  • Simple Operation Buttons: It is equipped with intuitive operation buttons such as direction keys and confirm keys, making it convenient for users to perform parameter setting, menu browsing, and other operations. In addition, it has two programmable function keys (F1/F2), which users can customize according to actual needs.
  • Rich Indicators: It is configured with 14 programmable three-color LED indicators, which indicate various operation statuses and alarm information of the device through different colors and flashing frequencies, enabling users to quickly understand the working status of the device.
• Strong Communication Capability: It supports multiple communication protocols such as RS485 and RJ45, which can easily communicate with upper computer monitoring systems or other intelligent devices, realizing remote monitoring, control, and parameter setting, and facilitating the construction of intelligent power monitoring systems.
• High Reliability: Based on Schneider Electric’s mature technology and rich experience, it adopts high-quality components and advanced manufacturing processes to ensure that the device can operate stably and reliably in harsh industrial environments. At the same time, it has a perfect self-diagnosis function, which can monitor its own working status in real-time and give an alarm in time when a fault is found.

• Industrial Field: It is widely used in the protection and control of motors in various industrial enterprises, such as factories, mines, metallurgy, chemical industry, electric power, and other industries. It can ensure the safe and stable operation of production equipment and improve production efficiency.
• Commercial Field: In commercial places such as shopping malls, office buildings, and hotels, it is used for the protection and control of motors in air conditioning systems, elevators, ventilation equipment, etc., to ensure the normal operation of these equipment and provide a comfortable environment for users.
• Public Utilities Field: In public utility fields such as electric power, water supply, and gas supply, it can be used to protect and control various motor equipment, ensure the normal operation of public facilities, and provide stable electricity, water, and gas supply for society.
