Finger-Safe Power Distribution Blocks

The Bussmann series PDBFS_ power distribution blocks offer IP20 finger-safe protection, high Short-Circuit Current Rating (SCCR) up to 200 kA, and a modular design. These UL Listed, single-pole blocks can be ganged together to form multi-pole configurations, meeting UL 1953 minimum spacing requirements for feeder circuit applications and NEC for field installations. They are designed to resolve common SCCR "weak links" in industrial control panels, ensuring compliance with NEC and OSHA requirements. Featuring dual-wire rated ports for copper or aluminum conductors and panel or 35 mm DIN-Rail mounting, these blocks are suitable for wireways and industrial control panel feeder and branch circuits.
