  Relays play a crucial role in electrical systems by controlling and protecting various components. Among the different types of relays, this article will focus on four essential ones: Under Voltage Relay, Over Voltage Relay, Start-Stop Relay, Photocell Relay, and Liquid Level Relay. Each type serves a specific purpose in maintaining the stability and functionality of electrical systems. Under Voltage Relay : Under Voltage Relays are designed to monitor and protect electrical equipment from voltage drops below a predetermined level. When the voltage falls below the set threshold, the relay activates, triggering an alarm or shutting down the connected equipment. This ensures that sensitive devices and machinery are not subjected to low voltage conditions that can lead to malfunctions or damage. Over Voltage Relay : Conversely, Over Voltage Relays act as safeguards against voltage spikes or surges. They monitor the electrical supply and, when the voltage exceeds a predefined limit, ...
