Circuit protection devices are electronic components designed to safeguard electrical circuits and the devices connected to them from various electrical faults and abnormalities. They help prevent damage to sensitive components, ensure the safety of users, and maintain the reliability of the overall electrical system. Here are some common used circuit protection devices: Fuses, Circuit Breakers, Surge Protectors, Overvoltage Protection Devices, Thermal Protection Devices, EMI/EMC Filters, Voltage Regulators,etc. The selection of the appropriate circuit protection devices depends on the specific application requirements and the level of protection needed.
