In industrial and commercial environments, equipment such as motors, pumps, and compressors are integral to operational efficiency. However, these devices are susceptible to damage caused by overload conditions—when the electrical current exceeds the rated capacity. This can lead to overheating, mechanical wear, and ultimately, failure.

    Enter overload protection relays. They are designed to monitor electrical current levels and automatically protect equipment from damage. When the current reaches a predetermined threshold, the relay disconnects the power supply, preventing further harm. This functionality is vital not only for protecting individual components but also for ensuring the safe operation of an entire electrical system.
