PDB UL Listed power distribution blocks
High SCCRs help improve equipment SCCRs
Now with dual wire rated ports
Bussmann series high Short-Circuit Current Rating (SCCR) power distribution blocks provide up to 200 kA SCCR and help achieve compliance with National Electrical Code (NEC®) and OSHA requirements by resolving a common SCCR “weak link” in industrial control panels.
Available in 1-, 2- and 3-pole panel mount versions with popular lineside and loadside port configurations, these blocks are UL® Listed and provide the requisite spacing between uninsulated opposite polarities or ground by meeting the UL 1953 1” through air and 2” over surface for 301 to 600 volt applications.
To increase application flexibility, these blocks feature dual-wire rated ports that accept copper or aluminum conductors while retaining a UL Listed status.
Optional covers are available to enhance electrical safety.
