"UL.com Ratings" data is publicly available with a free account at UL.com. The "Additional Data Sheet Ratings" are available for free on the manufacturers web site or by submitting a request directly. All 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. In addition, manufacturers may change the data on their web sites. At the time of this comparison you will find this information to be accurate to the UL web site as well as the manufacturers publicly available data. If you find any information requires an update, please bring to our attention and it will be updated immediately. |
Determining the acceptability of an SPD
for UL 1449 Surge Protective Devices 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 UL1449 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.
Approval Considerations Table based on UL SPD Type
| UL Mark | UL1449 SPD Type | Suitable Ratings | Procedure Described | File Update or Additional Testing | Notes |
 | 1 2 | Yes | No | No | The only requirement is that the SPD must match electrical and environmental ratings of the UL 67 Control Panel. A UL field inspection of the control panel with the SPD installed is required as a part of a standard follow-up service visit. |
 | 1CA 2CA 4CA 5 | Yes | Yes | Yes | Yes – 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. |
# What are Critical Operations Power Systems (COPS)
As stated by Article 708, Critical Operations Power Systems can be classed by municipal, state, federal, or other codes by any governmental agency having jurisdiction or by facility engineering documentation establishing the necessity for such a system. These systems include but are not limited to power systems, HVAC, fire alarm, security, communications, and signaling for designated critical operations areas.
