Feature/Benefits

• High Short-Circuit Current Ratings up to 200kA

PDBs do not have to be a weak link in achieving high

SCCR for an industrial control panel

• Suitable for installation in wireways (with optional covers)

and industrial control panel feeder and branch circuits.

Listed to UL1953 which has minimum spacing

requirements at 600V of at least 1” through air and 2”

Agency/Standards

• UL Listed 1953, Guide QPQS, File E256146

Electrical

• 600Vac or dc (UL 1953)

• Short-Circuit Current Ratings up to 200kA, see table

• 75ºC rated connectors, ampacities up to 310A

• Wire range 14 AWG to 350 kcmil CU

• Spacing between uninsulated opposite polarities or ground

meets UL 1953 which requires at least 1” through air and

2” over surface for 301 to 600V

Mechanical

• Panel mount

• Flammability, UL 94V0

• Tin-plated AL connectors suitable for CU conductors
