Series PDBFS of Power Distribution Blocks
Feature/Benefits
• Enclosed, safer
installation; IP20
finger-safe under specific
conditions
• High short-circuit cur rent
ratings up to 200kA:
PDBs do not have to be
the weak link in achieving
high SCCR for an
industrial control panel
• Small footprint saves
panel space
• Listed to UL 1953 which has minimum spacing
requirements at 600V of at least 1” through air and 2” over
surface required for feeders in UL 508A Industrial Control
Panels

• IEC 60947-7-1
• IEC 60529, IP20 (finger-safe) under specific wiring
conditions
Electrical
• 600Vac/dc (UL 1953), 690Vac/dc (IEC)
• IP20 finger-safe under specific conditions
• Short-circuit cur rent ratings up to 200kA, see table
• Ampacities up to 760 amps
• Cu wire range 14 AWG to 500 kcmil or 2.5 to 240 mm
2
Mechanical
• DIN rail or panel mount; PDBFS330 & PDBFS504 panel
mount only
• Captive termination screws; screws do not get misplaced
• Wire ready: captive termination screws shipped backed out
to save time on conductor installations
• Sliding DIN rail latch for easy mounting
• Single pole, gang mountable for multiple pole applications
with interlocking dovetail accessory (optional)
• Flammability, UL 94V0
• Tin-plated Al connectors suitable for Cu conductors
• Elongated hole for panel mounting; easier mounting with
greater flexibility in matching up with drilled panel holes
• Part 2A1279: Inter locking dovetail pin accessory
One pin interlocks two units, two pins to interlock three units
• DIN rail end anchors required to prevent damage to block
when torquing
