Determining the acceptability of an SPD for your UL equipment

(for UL 508A Control Panels and All Other UL Listed Equipment)

The UL inspector will first consider the SPD type when determining it’s acceptability for a given application or piece of equipment. This will include UL 508A as well as all other UL Listed equipment. The first level compliance is based on the UL Approval (LISTED or RECOGNIZED) of the SPD or UL SPD Type and it’s Suitable Ratings. This means that it has to meet all safety, performance, environmental and electrical system ratings of the application. If any of these criteria are not fully met, it will require a Procedure Description, a File Update and/or Additional Testing. These actions will require additional costs that may be substantial. For this reason, it is in the interest of the specifier to use UL LISTED SPD’s to eliminate any uncertainty or to make sure the UL RECOGNIZED SPD is selected at the time of UL submittal of the equipment.

A UL field inspection of the control panel with the SPD installed is required as a part of a standard follow-up service visit.

YesYesYesYes – All UL recognized SPD’s require a UL engineering evaluation of the SPD’s existing UL1449 E–file.

This will result, at a minimum, in a cost to update the UL file and may also require testing that would result in additional costs.
UL data is publicly available with a free account at UL.com. The data has been reviewed by our engineering department. From time to time, the applicants UL file (including CITEL's) may become changed or updated at UL.com due to new testing or corrections to a report. At the time of this comparison you will find this information to be accurate to the UL web site.
