Knowing industry guidelines can save you money and enhance performance. The vast array of surge protection devices, and the ratings that characterize them, can be confusing. How do you sort through ...

When it comes to surge current ratings, more isn’t necessarily better. Some SPD products have fuses with excessive surge current ratings. These designs may provide the proper system coordination, but ...

KOA Speer Electronics has launched the NV73S series of multilayer metal-oxide varistors, which handles a surge current of up to 6,000 A, claiming five times higher protection than existing products.

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.

While 80% of surges originate internally from normal operations like motor starts and VFD inverter operation, external causes like lightning and utility switching also demand industrial-grade surge ...
