SCHURTER now offers radial leaded varistors, also referred to as MOV (Metal Oxide Varistors), which help to protect electronic circuits against surge transients, such as can be caused by lightning ...

For a device that's plugged into the surge protector, this means that it doesn't get hit by the sudden increase in voltage: the varistor lets it pass through harmlessly to earth.

The Metal Oxide Varistor (MOV) is the part of the surge protector that absorbs excess voltage and dissipates it as heat to ground. So, you may think that the more MOVs in a surge protector, the better ...

One aspect of ac motor protection is the surge-withstand capability of the motor itself. Paragraph 20.36.4 of the NEMA motor generator standard MG-1 defines a unit value of surge as: ...

TDK Corporation presents the new high-surge series of EPCOS multilayer varistors. These are characterized by their high surge current capability, ranging from one surge of up to 5000 A to ten ...

The typical home sees a 100V surge hourly and a 1000V surge monthly. However, most residential customers don't know how to protect their expensive entertainment centers, home networks, computers, and ...

The NV73S replaces the NV732E (1210) through 2L (2220) due to its improved surge protection. Maximum peak current and sizes for the new NV73S are 400 to 800A (1210), 500 to 1,200A (1812), and 1,500 to ...

Not all surge protectors are built this well. If you need a refresher on how varistors work, we can help with that. Continue reading → ...

Surge protection is rated at 500 volts for each of the three legs of a ground power circuit: live-neutral, live-ground, and ground-neutral (L-N, L-G, and N-G). That’s a reasonable value for ...

Series mode units can activate the suppression as soon as the voltage goes over the norm instead of waiting for a high surge. In 1989, Zero Surge, Inc., Frenchtown, New Jersey, pioneered series ...
