Product Overview
V250LA20AP is a Littelfuse LA-series radial MOV with a 250 VAC RMS continuous rating. Although the model contains “20A,” the datasheet identifies this orderable as a 14 mm disc device; that distinction matters when comparing it with the larger V250LA40AP 20 mm version.
The V250LA20AP provides 72 J energy capability and a 4.5 kA peak 8/20 µs surge-current rating in the 14 mm body.

Replacement Considerations
Do not infer disc diameter from the “20” portion of this LA-series model number. For mechanical and surge-rating equivalence, verify the exact V250LA20AP code rather than substituting V250LA40AP or another 250 VAC family member.
