Introduction to Overcurrent Protection Device

An overcurrent protection device is designed to protect electrical circuits and connected equipment from excessive current caused by overloads or short circuits. When the current exceeds the rated safety limit, the device automatically interrupts the circuit to help prevent overheating, equipment damage, and potential electrical hazards.

Overcurrent protection devices are widely used in residential, commercial, and industrial electrical systems to enhance electrical safety and ensure reliable operation. By providing effective protection against abnormal current conditions, they help reduce the risk of electrical failures and extend the service life of electrical equipment.
