Electromechanical Overcurrent Relay
Two of three phase motor currents are monitored by current transformers. External Cts are required for currents more than 60Amps.
Introduction
As a leading manufacturer in China, we are proud to introduce our top-of-the-line Electromechanical Overcurrent Relay. Designed to meet the needs of various industries, our relay is a reliable and cost-effective solution for protecting against overcurrents. With decades of experience, we are confident in offering the highest quality products possible, and our Electromechanical Overcurrent Relay is no exception. In this product introduction, we’ll detail key features merchants will find attractive, such as design, functionality, and durability.
Design
Our Electromechanical Overcurrent Relay features a unique design that sets it apart from other options on the market. It’s compact, making it easy to install and integrate into any system. The relay is designed for easy installation without the need for additional tools or equipment, making it an excellent solution for those who require quick and easy protection for their systems.
For optimal efficiency, the relay has a clear indication of status, so you can quickly determine if it is working correctly. The clear and concise display allows merchants to monitor and adjust it with ease.
Functionality
The Relay performs two critical functions. First, it prevents overcurrents, protecting the connected electrical components from damage. Second, it stops any short circuits or overload that might occur in the circuit. This ensures that the circuit remains operational and minimizes downtimes.
The Electromechanical Overcurrent Relay has an adjustable trip current range that makes it possible for the merchant to customize it according to their needs. This adjustable trip current range is an added advantage, promoting versatility and flexibility.
Durability
The Electromechanical Overcurrent Relay is built to last. Made from high-quality materials, it can withstand harsh elements while remaining reliable and functioning at peak performance. Furthermore, the relay meets all international safety standards and comes with all the necessary certifications. You can rest assured that your system will remain functional without any safety concerns.
Additionally, the relay is easy to maintain since it comes with a user manual that guides merchants on how to maintain and troubleshoot the relay in the event of a malfunction.
Conclusion
Our Electromechanical Overcurrent Relay is an excellent solution for merchants looking for a cost-effective means of protecting their electrical components. With a compact design that integrates easily into any system, customizable trip current range, and robust durability, it is a reliable safety solution. You can rest assured that your systems will remain secure and operational with our Electromechanical Overcurrent Relay. We take pride in creating high-quality products that meet the needs of our clients. Contact us today to learn more about how we can assist you with your overcurrent safety needs.

The description of electromechanical overcurrent relay
Two of three phase motor currents are monitored by current transformers. External Cts are required for currents more than 60Amps. The internal solid state circuitry compares with the preset current level. When load currents exceeds the preset trip level, red LED illuminates, and after the preset time, the device trips, and changes internal SPDT relay contacts,red LED remains illuminated indicating an overload trip has occurred.Until manual or remote electrical reset by interrupting supply is initiated.
If load current falls off below set point before the preset delay resets trip timer.With the visual aid of LED, flashing at 100% of preset load, actual load currents can be determined without the aid of Ammeter. TEST button provides the means of testing service-worthiness and integrity of the device. Internal relay is energized in normal operation condition(fall-safe) and will not become ready mode with either supply lost or own failure.
Starting delay time range:0.2-30 seconds.
Trip delay time range:0.2-10 seconds. May be used as electronic shearpin by setting trip time to minimum.
