Littelfuse offers specific Varistors and Classes of Fuses to address over-voltage and over-current transients in the Industrial environment. This application area is typically characterized as AC utility service entrance and distribution, and the associated high current inductive loads that can include medium and heavy motors. Transient over-voltage suppression in these applications typically require Industrial Metal Oxide Varistors (MOVs) for induced lightning surges or for switching transients created by the motor itself.These situations demand that the MOV ratings match the surges found in these locations in terms of suitably high energy and surge current values. Similarly, in selecting a load Fuse, it must obviously be of a value that will allow normal operation, including the allowance for certain fault conditions, but at the same time not open for the transient surges that the MOV is intended to suppress.
