The small footprint, high short circuit current (SCCR) Bussmann® series power distribution blocks provide IP20* finger-safe protection under specified conditions. These UL® listed, single pole blocks are of a modular design that permits dovetailing together the required number of poles for an application and still meet the UL 1953 minimum 1" and 2" spacing required per UL 508A for feeder circuit applications and per NEC® for field installations. 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.
