What Is Clamping Voltage? How It Protects Your Devices

What is Clamping Voltage?

I used to think clamping voltage, let-through voltage, and breakdown voltage were all the same—until a power surge fried my microcontroller despite having protection in place. If you’ve ever wondered why surge protectors sometimes fail, you’re not alone. In this article on the Tech4Ultra Electrical website, I’ll break down the real differences between these key voltage terms

What Is Available Fault Current and How to Calculate It

What is Available Fault Current?

Do you know the difference between available fault current, fault current, and prospective short-circuit current? Many new engineers confuse these terms, even though understanding them clearly can make a huge difference in electrical safety and protection system design. In this article on the Tech4Ultra Electrical website, I’ll break down each concept in simple terms, share my personal
