Circuit Protection

Circuit protection is a critical aspect of electronic design and engineering aimed at safeguarding electronic components and systems from damage caused by electrical faults or overloads. The primary purpose of circuit protection is to ensure the reliability and longevity of electronic devices by preventing excessive currents or voltages from causing harm.

Common circuit protection devices include fuses, circuit breakers, surge protectors, and varistors. Fuses and circuit breakers interrupt the flow of current in the event of a fault, while surge protectors and varistors absorb and redirect excess voltage, protecting sensitive components.
