Protect expensive equipment from excessive surges caused by thunderstorms and potential differences.

No one can protect themselves against a hit, but the vast majority of injuries are due to a lightning strike up to several kilometers away, where a very short but powerful surge occurs through the copper cable connection. However, there may also be strong surges from the power supply, and damage usually goes beyond the weakest link in the chain, for example. network equipment such as routers and switches.

The ongoing development of electronic technology results in highly advanced electronic equipment in companies and our homes in the form of video, audio, security, computers and appliances. Miniaturization of these products also makes them susceptible to interference from lightning and load shifts.

Therefore, the right protection unit can save a lot of money and time.

Pass-through device that provides galvanic isolation can greatly benefit also from unintentional potential differences and poor grounding.

Transient protection transducers (overvoltage protection) are provided with a number of powerful transsorb components that direct the high voltage to the frame.

If the energy in the overvoltage is large, it will also destroy these protection components. Therefore, it is important to review your own installation to find defects and earthing errors for the equipment. If there is no consequence in the installation, an error grounding can result in greater destruction if there is no ground.
