Power distribution block Eaton PDB220-1 with UL listed status and 200 kA short circuit current rating
Product Overview
Eatons Bussmann series high Short-Circuit Current Rating (SCCR) power distribution blocks are designed to enhance compliance with National Electrical Code (NEC) and OSHA requirements by addressing common SCCR limitations in industrial control panels. These blocks offer up to 200 kA SCCR and are available in 1-, 2-, and 3-pole panel mount versions. They meet stringent UL 1953 spacing requirements for feeder circuit applications and field installations, ensuring safety by providing adequate separation between uninsulated opposite polarities or ground. The dual-wire rated ports accommodate copper or aluminum conductors, maintaining UL Listed status and increasing application flexibility. Optional covers are available for added electrical safety.

* 75C wire (higher temperature rated wire acceptable with appropriate derating). Using a ferrule on a stranded conductor requires a correctly sized UL Listed ferrule (customer supplied) applied according to the manufacturers specifications. Ferrule ratings apply to copper wire only.
** See pages 4 and 5 for the tested upstream overcurrent protective devices necessary for achieving these SCCRs.
Torque rating for dual wire and ferrule application is 30.5 Nm (270 Lb-in).
Torque rating for ferrule application is 13.6 Nm (120 Lb-in).
