Electronic motor relay 5A In=5A Un=230V TH-35 EPS-D 5A

Electronic motor relay – comprehensive protection for motors and installations

This microprocessor-controlled EPS-D 5A motor relay is an advanced device designed to protect three-phase electric motors. It provides reliable control and protection in a wide range of applications, from pumps and boosters to elevators, conveyors and compressors. Its versatility makes it an ideal choice for both professional installers and end-users looking for solid protection for their equipment.

Functionality and application

The EPS-D relay not only protects the motor from failures but also monitors its operation under various conditions. Equipped with an analog temperature sensor input and a ground fault detection module, it allows for precise control of the device's status. The ability to connect to the system via a through connection simplifies integration with existing infrastructure. This allows it to be used in new installations as well as to modernize existing systems.

This relay performs well in applications requiring high reliability and precise control of motor operating parameters. Its wide rated voltage range (160…242 V at AC 50/60 Hz) and operating current (1…5 A) make it compatible with various types of motors and electrical installations. The IP40 protection class provides resistance to dust and other contaminants, ensuring long-lasting and trouble-free operation even in harsh environmental conditions.

Advanced protections for your motor

EPS-D offers comprehensive protection for the motor against various threats:

• Thermal protection: Protects against motor overheating, which extends its lifespan.
• Protection against no-load operation and dry running: Prevents damage resulting from lack of load or improper lubrication.
• Protection against mechanical overload: Protects the motor from damage caused by excessive load.
• Protection against rotor locking: Detects a blocked rotor and shuts off the motor, preventing more serious failures.
• Protection against phase failure or phase sequence change: Protects the motor from damage caused by incorrect power supply.
• Protection against load asymmetry: Prevents damage resulting from uneven phase loading.
• Protection against ground fault: Ensures the safety of users and protects the electrical installation.

Additionally, the relay has (2) analog inputs allowing connection of external temperature sensors or other parameters monitored in the motor's operating process and a current detection module increasing the functionality of the device.
