AI summary

VDR20D-511K product

VDR20D-511K is a 20 mm radial MOV rated for 320 VAC continuous operation, intended for transient suppression where its 845 V maximum clamp at 100 A is acceptable.

Best for

AC-input transient suppression
Power-line surge protection with external circuit protection

Avoid if

The circuit requires a clamp voltage below 845 V at 100 A
The expected surge energy or current exceeds the stated ratings

Check before use

Continuous AC or DC voltage
Surge waveform, peak current, and energy
Fuse or disconnection method
Lead spacing and enclosure clearance
