Relays are integral components in electrical systems, acting as automated switches that help control and protect circuits from potential faults. With increasing demands for reliability and safety in modern electrical infrastructure, the importance of relay safety features cannot be overstated. These features are designed to ensure that electrical systems operate safely, efficiently, and without causing damage to both equipment and personnel. This article will explore the key safety features of relays, including overcurrent, overvoltage, short circuit, and temperature protections, which collectively contribute to the overall safety and performance of electrical circuits.
