Is Clamping Voltage Important?
Yes. It is one of the primary specifications of a surge suppression device. Remember, until voltage exceeds the rated clamping voltage, the device does nothing. It only stands to reason that clamping voltages at levels as close as possible to the NORMAL operating requirements of the equipment makes good sense. An organization can claim that equipment is designed to accept elevated voltages (for example, CBEMA indicates that voltages as high as 300 volts on a 120 volt line are of minor concern), and be absolutely correct. Here’s an example. You can run your car completely out of oil or water and survive the event if you shut it down soon enough. It doesn’t mean that your car will be undamaged by the event…only that the damage done THIS time wasn’t enough to kill it. IMPORTANT! You can build a device with the lowest voltage possible…and render it no more effective than the cheapest device through improper installation.
