UL 1449 3RD EDITION CHANGES
5
Codes Standards UL 1449 3rd Edition / IEEE
C62.41

• Overview
• Effective September 29, 2009
• Name Change to Surge Protective Device
• Category A,B,C changes to Type 1,2,3,4
• New Product Testing Requirements
• Inclusion of Nominal Discharge Current In

6
Codes Standards UL 1449 3rd Edition

• Effective September 29, 2009
• All Surge Protective Devices manufactured after
  this date must be compliant with UL testing
  parameters and performance ratings
• Many manufacturers are opting to be tested at
  other NRTLs
• Make sure specifiers are aware of the difference
  when it comes to components and integral offers,
  i.e. if component is not Recognized or Listed by
  Underwriters Laboratories, the entire assemblys
  Listing may be in question. (local inspector
  may question, UL may not back entire assy)
• ALL EFI devices will be listed with Underwriters
  Laboratories by September 29, 2009

Codes Standards UL 1449 3rd Edition

• Product Testing Changes
• Measured Limiting Voltage title changes
• 2nd ED.- Surge Voltage Rating (SVR)
• 3rd ED.- Voltage Protection Rating (VPR)
• Testing parameters (Increased performance)
• 2nd ED.- 6kV/0.5kA
• 3rd ED.- 6kV/3kA (6 times the current level)
• 3 impulses per mode of 6kV, 3kA using 8/20 wave
  shape
• 15 impulses per mode of 6kV, NDC (In)
• 3 impulses per mode of 6kV, 3kA
• Product must be within 10 of baseline readings
  in determining In ratings

Codes Standards UL 1449 3rd Edition

• Product Testing Changes
• New Nominal Discharge Current (In) Values on
  label
• Type 1 10kA, 20kA
• Type 2 3kA, 5kA, 10kA, 20kA
• Type 3 3kA

Codes Standards UL 1449 3rd Edition

• What Will Be Different with EFI Products?
• The only noticeable difference will be In and VPR
  ratings on product labels
• Form, Fit and Function and literature will remain
  the same throughout lineup
• Part numbers will not be changing
• The numbering protocol will remain the same
• Devices will remain EFI branded, not Schneider
  Electric
