Why Use Surge Protection?

Surge protectors protect personnel and equipment from damaging high-voltage surges from lightning, inductive switching, nuclear electromagnetic pulse, electrostatic discharge, or interference from power supply lines. From a design point of view, protection circuits only cost money and, if customer requirements or regulatory agencies do not require them, they will easily be forgotten. Yet, appropriate surge protection is beneficial. Protected equipment will not be affected by the highvoltage surges listed above. This will result in:

• Reduced field failures

• Improved product quality and reliability

• Reduced cost of quality

The figure below illustrates the cost effectiveness of adding surge protection by demonstrating the unit repair cost to break even over a range of return rates for added protection costs of $0.50/unit and $1.00/unit.

Through ongoing research and engineering improvements, Littelfuse has developed a family of Surge Protection Products that offer impressive characteristics for a variety of applications. Four differentiating characteristics are found in every Littelfuse Surge Protection Product:

• High surge current rating

• Long life

• Fast response

• Rugged construction

A Comparison of Surge Arrester Technologies

In today’s world of sensitive electronics, an increasingly important topic has become the protection of electronic components from overvoltage surges. There is a multitude of devices on the market for this purpose but what are the differences between them and which is best for what application? The following describes, analyzes, and compares these devices in detail. Basically there are two types of surge protection classifications with each consisting of its own group of devices:
