What is the role of voltage rating in protection devices?

The role of voltage rating in protection devices is crucial as it ensures that the device can operate safely at specific voltage levels. This rating indicates the maximum voltage the device can handle without risk of failure or dangerous malfunction. If a device is operated beyond its voltage rating, it can lead to insulation breakdown, overheating, or even catastrophic failure, posing a safety hazard to both equipment and personnel.

In electrical and electronic systems, knowing the correct voltage rating helps prevent overvoltage situations, which can damage the device and create risks of electric shock or fire. Therefore, the voltage rating is an essential specification that must be adhered to for safe and reliable operation of protection devices.
