ALSTOM P4309893020C0D0B motor protection relay

Product Details Introduction

ALSTOM P4309893020C0D0B is a motor protection relay commonly used to protect motors from overload, short circuit, phase sequence error, and other electrical faults. The following are the general characteristics and possible application areas of the protective relay:

Main features:

Overload protection: Monitor the current of the motor, trigger the protection action when the current exceeds the set value, and prevent the motor from being damaged due to long-term overload.

Short circuit protection: detects short circuits in the circuit, quickly cuts off power, and prevents damage and danger caused by circuit short circuits.

Phase sequence protection: Monitor the phase sequence of the motor power supply to ensure that the motor operates in the correct phase sequence and avoid motor damage caused by phase sequence errors.

Current monitoring: Real time monitoring of motor current changes, timely detection of abnormalities, and taking protective measures.

Temperature protection: Monitor the operating temperature of the motor to prevent damage due to overheating.

Remote Communication: Supports remote monitoring and communication functions, enabling users to monitor motor status in real-time and remotely operate protective relays.

Application areas:

Industrial motor control:

Used in industrial production lines, pump stations, and compressors to protect motors from electrical faults such as overload and short circuits.

Water pump and fan:

In water treatment and air conditioning systems, it is used to protect pumps and fan motors, ensuring stable operation and long lifespan of the system.

Power system:

In power plants and substations, motors are used to protect generators and power transmission equipment, ensuring the safety and reliability of the power system.

Transportation:

In railway and subway systems, protecting motor-driven trains and signal equipment ensures the safe and efficient operation of the transportation system.

Building facilities:

Used in the management of large buildings and facilities to protect electrical equipment in elevators, air conditioning, and water supply systems.

ALSTOM P4309893020C0D0B motor protection relay, with its multiple protection functions, can effectively protect motor equipment from electrical faults and is one of the important protection devices in industry and infrastructure.
