Alternate for Varistor TNR15G431KM

Looking into part number TNR15G431KM, originally made by a company called Marcon, I was able to find at least a decent alternative option if anyone is looking for these. I had to use a third party site (linked here) to find a scan of the old data sheet which gave me the following specifications.


Maximum Continuous Voltage: 275VAC, 369VDC
Maximum Peak Current: 4kA
Maximum Energy: 75J, for 1msec
Clamping Voltage: 50A; 700V
Capacitance @1kHz: 480pF
Varistor Voltage: 430 nominal (min-max is 389-473)
Alternate GE Model Number: V275LA15A

The ā€œAlternate GEā€ number was a dead end for me, but using these specifications I was at least able to find a decent alternate in part number F3021-ND.
