Specifications are subject to change without notice.

Users should verify actual device performance in their specific applications.

SV Series - Special Medium Voltage Varistors

Full Custom Parameter Designed Medium Voltage Varistors

The SV series of full custom parameter designed varistors consists of square and

rectangular shaped varistors, available either as epoxy coated lead style components or

as metalized pellets.

The customer can specify the varistor electrical properties and set the limits of size

parameters in accordance with the General Technical Data, as provided below. The

customer can also choose to have standard electrical parameters in a non-standard

varistor shape and size to best fit the available housing. The customer has our full

engineering support to help realize his specific protection requirement.
