Description

POWR-BLOKS power distribution blocks offer a safe,

convenient way of splicing cables, providing a fixed junction

tap-off point or splitting primary power into secondary

circuits. Lx2xxx-DIN series offers integral DIN-Rail mount

and an optional hinged safety cover.

Optional power distribution block covers provide protection

against accidental shorting between poles caused by

loose wires, tools, or other conductive material. They also

protect personnel from accidentally contacting energized

connectors.

Applications

Typical applications include heating, air conditioning and

refrigeration systems, elevator systems, material handling

equipment, control panels, motor controls, switchgear,

and anywhere power needs to be distributed to more

than one load.

Connectors

Box lug connectors are designed for use with a single or

multiple, solid or class B or C stranded conductor. For UL

approved use of more than one conductor per connector

opening, contact Littelfuse Technical Service. Manufacturers

of cable terminations can furnish crimp-on sleeves for fine

stranded conductors which permit these conductors to be

used with box lugs.

Ampere Ratings

The ampere rating per pole for power distribution blocks is

based on the line ampacity of 75°C insulated conductors per

load must not exceed the ampacity of 60°C conductors.

Use of conductors rated in excess of 75°C is permitted (for

example 90°C), however, load must not exceed the ampacity

of 75°C conductors.
