BUCHANAN Terminal Blocks

Product Facts

nNo Wire Crimping Required

—tubular clamp contacts

hold wire ranging from #30

to #12 AWG better than

crimp-on terminals.

nSaves Installation Time and

Costs — tubular clamp

contacts are supplied with

captive screws backed out.

nNylon housing standard;

polypropylene for fire

retardant characteristics.

nPositive Stop — helps

prevent wire from being

inserted too far, and helps

prevent screw from being

tightened on insulation. Easy

access contact provides for

safe, reliable, and cost-

effective connection.

nQuick Installation and

Change — additional

sections may be added or

removed without removing

channel mounting screw.

nChoice of Five Mounting

Channels:

nMiniature aluminum

nZinc-plated steel

nPre-punched aluminum

nBreak-away steel

nSingle and Double Tier

blocks fit all standard

BUCHANAN mounting

channels. Single Tier blocks

fit both miniature and

standard channels.

nChoice of Marking Surfaces

—matte-finish area for

marking directly on block;

slide-in vinyl strip (blank or

preprinted) also available.

LR25557 E63810

These miniature terminal

blocks fit on a much smaller

channel to save valuable

panel space or can be

surface mounted directly to

the panel. Miniature blocks

accept wire as large as #12

AWG and are available in

four styles: Miniature

(nylon), Miniature

(polypropylene), Single Tier

and Double Tier.

Physical Properties

Effect of Radiation on Physical

Properties

The effects of radiation (neutron and

gamma particles) on RYTON R-4

material have been studied. Since

RYTON, as an engineering plastic, may

fill applications in nuclear installations

these effects are important. The test

results show no effects on physical

properties by these relatively high

exposures to gamma and neutron

radiation. There is no indication from

these data of crosslinking or degradation

of the RYTON R-4 material.

Note: Determination of the suitability of

the ERT Series Blocks for particular

applications rests solely with customers.

Product Facts

nChoose from 5 different

contact styles.

n600 volt UL and NEMA

rating.

nConservatively rated from 50

to 90 amperes per circuit,

depending on which contact

style is selected.

nChoose any of three

mounting methods — two-

way flat base models surface

mount directly to the panel

or snap-on miniature

channel. Dovetail base

models mount on standard

channel.

nPackaged for rapid handling

and assembly — snap-fit

sections are packed 10 per

carton.

nOnly one end section needed

per block assembly.

nReadily identify circuits —

mark directly on block

sections or use removable

marking strip. Pre-printed

strips are also available.

BUCHANAN Terminal Blocks

Product Facts

High Density Blocks

nFuse and Switch Blocks rated

15A and 300V.

nHigh Density 0.36" [9.14]

centerline spacing saves

panel space; at least 33

circuits per foot.

Fuse Blocks

nProvide in-line circuit

protection for virtually any

circuit or group of circuits —

select contacts for

terminated or unterminated

wire.

nRemove, check and replace

fuses safely and quickly —

switch action fuse blocks

open circuits before fuse can

be removed or installed.

nContacts conservatively

rated to 30 amperes.

Switch Blocks

nQuickly and easily interrupt a

circuit or group of circuits —

insert switch blocks directly

in line. Contacts available

for terminated or

unterminated wire.

nKeep circuits open for

extended periods — switch

blade can be removed

entirely from block for lock-

out protection.

nRated to 15 amperes.

Common Features of 300 &

0300 Series

nAt least 91 circuits per 6-foot

length, 3/4 inch center-to-

center spacing.

nBlocks meet 600 volt

clearance and creepage

spacings specified in UL,

CSA, and NEMA Industrial

Control Standards.

nChoose nylon housing

material — for more rugged

applications; polypropylene

for fire retardant

characteristics.

nDovetail base fits standard

mounting channel — can

also be mounted on flat

surfaces.

nOnly one end section needed

per block assembly.

nReadily identify circuits —

mark directly on white,

matte-surface puller

assembly, marking tab on

block, or use removable

marking tape.

nOpen or close several

circuits simultaneously —

holes in puller handles allow

use of nylon “ganging” rods.

nFuse and Switch block

sections snap-fit with 300 &

600 Volt, phenolic Medium

Duty, Heavy Duty, and

Intermediate Heavy Duty

blocks.

Marking Strip Installed

On A Factory-Assembled Terminal Block

Circuit identification is

greatly simplified with the

use of pre-printed strips for

BUCHANAN terminal

blocks. These hot-stamped

strips are available for all

snap-assembled sections

(except Fuse, Switch, and

Circuit Breaker models

which are marked

individually). The strips can

be ordered separately or

pre-installed on factory

assembled sectional block

units.

Unlike painted or screened

letters, hot-stamped letters

are designed to not rub or

flake off during industrial

use so that they will retain

their legibility.

Marking strips are stamped

with consecutive numbers

that can be ordered to read

from left-to-right or right-to-

left, and in vertical or

horizontal positions.

Number sequences can

begin with any number.

This allows circuits to be

identified in a manner most

consistent with the terminal

block application.

BUCHANAN Terminal Blocks

UL 1059 Basic Voltage Rating

Voltage ratings of terminal blocks are based on the minimum spacing between electrical conductive parts of opposite

polarity or between an electrically conductive part and a metal mounting surface measured under two conditions: Through

Air, defined as the distance an arc must take through the air to go from one live conductor to another or from a live

conductor to ground; and Over Surface, defined as the distance an arc must take over a surface of the insulating material

going from one terminal to ground, assuming the arc will travel along the surface rather than through the air. The following

chart shows UL 1059 spacing requirements in inches.
