How To Specify The Appropriate Model:
All LM model numbers begin with a LM prefix. Use
Chart A
to build your LM starting with the Surge Rating column. Moving left to right,
choose the correct configurations from each column for your application. Your completed model number should look similar to the example
below or LM250120YARCE. Refer to
Chart B
for LM Series dimensional data.
