Distribution Blocks • Splicer Blocks • Covers

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. To order protective covers, match the number

of poles for the block to the cover.

Applications

Typical applications include heating, air conditioning and

refrigeration systems, el e va tor 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, solid

or class B or C stranded conductor. Use of more than one

con ductor per connector opening or use of extra-ﬂexible,

ﬁne-stranded conductors, such as welding cable, voids the

UL Listing and may cause overheating. Manufacturers of

cable ter minations 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

NEC

Table 310.16. If 60°C insulated conductors are used,

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.
