How To Specify The Appropriate Model:

All Liebert Interceptor II model numbers begin with the SI prefix. Use Chart A to build your Liebert Interceptor II 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 SI016120YARDE. Refer to Chart B for Liebert Interceptor II dimensional data.
