A Guide for Sales Reps ANSI/UL 1449 Third Edition Field Summary SPD TYPE: UL now categorizes surge protective devices (SPD) into categories based on its intended application. •TYPE 1 - Connect anywhere in the customer’s facility – we strongly urge this to be specified for all critical installations. •TYPE 2 - Connect downstream on load side of main breaker. Be aware that some competitors may have “conditions of acceptability” that can limit how the device is installed. •TYPE 3 - Typically cord connected, plug in devices. •TYPE 4 - Components Nominal Discharge Current (I Nominal Rating): This is the peak value of surge current which goes through the SPD (15 surges). •TYPE 1 - UL tests to 10kA or 20kA. Not to be confused with maximum kA rating of the device. We recommend 20kA I Nominal rating be specified. While this is the highest UL rating, it is a low level surge which should be required by any device in even moderate exposure installations. •TYPE 2 - UL tests to 3kA, 5kA, 10kA or 20kA I Nominal ratings. Again, 20kA is recommended for all specified SPDs located at service entrances. Voltage Protection Rating (VPR): These ratings replace the Suppressed Voltage Ratings (SVR) of the prior standard. UL uses a surge six times the kA level of the SVR testing, so ALL VPR ratings are higher than SVR ratings. SPD Locations by UL 1449 Types Summary: This new standard presents a great opportunity to educate your engineers on the advantages of Liebert Surge Protection products. Our long-standing surge and fuse technology allowed us to meet/exceed this standard long before it became a requirement. When revising specifications with your engineers, require the most stringent category and classification of SPDs: Type 1, 20kA I Nominal for all service entrance applications. Further, encourage the official UL mark as a requirement on all products as the testing authority of choice. Headquarters Ordering Information: Liebert SI (Interceptor), LM and Type SS Products: •All standard part numbers will be listed as Type 1SPD with an I Nominal of 20kA. This Type 1rating allows the greatest flexibility, since the SPD can be applied in any location.
