PDBFS finger-safe power distribution blocks

High SCCRs help improve equipment SCCRs

Now with dual wire rated ports

The small footprint, high Short-Circuit Current (SCCR) Bussmann series power distribution blocks provide IP20 finger-safe protection under specified conditions. These UL® Listed, singlepole blocks are of a modular design that permits dovetailing together the required number of poles for an application and still meet UL 1953 minimum 1” and 2” spacing requirements.

With SCCRs up to 200 kA, these blocks help achieve compliance with National Electrical Code (NEC®) and OSHA requirements by resolving a common SCCR “weak link” in industrial control panels.

To increase application flexibility, these blocks feature dual-wire rated ports that accept copper or aluminum conductors while retaining a UL Listed status.

With panel or 35 mm DIN-Rail** mounting for application flexibility these blocks are suitable for installation in wireways and industrial control panel feeder and branch circuits.
