Feature/Benefits

• Enclosed for enhanced

safety; IP-20 finger-safe

under specific conditions,

see page 8

• High Short-Circuit Current

Ratings up to 200,000A:

PDBs do not have to be

a weak link in achieving a

high SCCR for an

industrial control panel

• Suitable for installation in

wireways 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” over surface

• Small footprint saves panel space. Stack side by side and still

meet 1˝ and 2˝ spacing requirements

• For 2D and 3D CAD drawings visit www.cooperbussmann.com

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 installation

• Sliding DIN rail latch for easy mounting

• Single pole, gang mountable for multiple pole applications

with interlocking dovetail accessory (optional Part 2A1279)

One pin interlocks two units, two pins to interlock three units

(see illustration on page 6)

• 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

• DIN rail end anchors required to prevent damage to block

when torquing, anchors not offered by Cooper Bussmann
