VARIO™ Loadbreak Switches

VARIO™ Loadbreak Switches act as enclosure disconnects when shor t circuit protection is provided

upstream of the switch (if short circuit protection is not provided upstream, use Class 9421 Type N, Class

9422 Type T, and D10 disconnect s witches). Type V s witches are UL Listed as manual motor controllers.

qComplete switch includes handle operator, shaft, do or interl ock pl ate, and line terminal shro ud.

Non-Metallic Enclosures

The V ARIO Loadbreak Switch is also offered as an enclosed switch, which is made of corrosion resistant

mater ial suitable for IP55 environments. The 3-pole version makes the VARIO Lo adbreak Switch ideal

f or manual motor control applications. They are compact, easy to wire and connect, and come undrilled

to allow variable cab le entry positions. Note that these enclosures do not pass the UL Burn Test, which

means that these versions are not UL Listed.

Metallic Enclosures

The V1and V2 come in metallic enclosures (NEMA Type 1, 4, 4X, and 12). The NEMA Type 1 is supplied

with conduit knockouts top and bottom. A VZ7 auxiliary contact can be f actory installed in these metallic

enclosures by adding F orm X11 to the catalog number . A VZ20 auxiliary contact can be factory installed

in these enclosures by adding F orm X20 to the catalog number. Two V27 auxiliary contacts may be f ac-

tory installed by adding Form X22 (2 N.O. and 2 N.C.).

pFor indoor use only. The NEMA 4/4X enclosure is made of #304 stainless steel with 3/4 in T&B stainless steel hubs on the top and bottom.

NEMA-Style Door-Mounted Disconnect Switches (D10)

A complete installation i ncludes a D10 disconnect switch, D11 handle operator, and D12 fuse clip kit.

The D10 accepts Class H, K, J , or R fuses — or can be used for non-fusib le applications. The D10 dis-

connect switch is operated by a cast metal handle operator that is lockable in the OFF position and de-

featable in the ON posi ti o n. Other features of the D10 disconnect switch are:

•High I2T rating – This switch meets automotive and heavy-industry requirements.

•Longer contact life – Quick-make, quick-break, cam-trip, and spr ing-loaded action throws the

switch into the ON p osition under pressure. This provides a quick-break when switching to the

OFF position. The double-break contact principle also assures lo nger life and exceptional inter-

rupting capacity.

•Visible contact indication – Clear ON and OFF markings plus actual contact positions are both

visible through pole “windows.”

•Fuse-mounting flexibility – Fuse clips are mounted on top of the switch, providing a compact

unit. Interchangeable fuse-clip kits are available for quick adaptation to other ratings.

•Dead-front construction – When the switch is in the OFF position, all visibl e current-carrying

parts are de-energized, thus providing additional safety for maintenance electricians.

•Auxiliary interlocks – One- or two-pole interlocks can be added to the disconnect switch when

required.

Class 9422 Handle Mechanisms

Handle mechanism kits are used with all disconnect switch and circuit break-

er installations. The kits contain all parts necessary for mounting the handle

to the flange of the enclosure. The Types A1 through A4 and A9 through A10

are suitable fo r right or left hand flange mounting. Two mounting methods are

offered. The Types A5 through A8 handles are designed for right hand

mounting only

Class 9422 Mounting and Outline Dimensions for

A1, A2, A3, A4, A9, and A10 Handles

All dimensions are shown for right-hand flange mounting. For left-hand

flange mounting, transpose all horizontal dimensions. See page 23 for infor-

mation on A5 through A8 handles.

Dimension X

Dimension X is the distance from the top inside of the enclosure or other

grounded metal parts (such as conduit hubs) to the upper mounting hole of

the handle mechanism (See Panel Drilling diagram). Actual distances are de-

pendent on the disconnect device being used, and should only be deter-

mined once the diconnect device is decided upon and the location on the

panel determined.

Preferred Mounting Method

This method is for 16 Ga. to 0.25” thick enclosures. It consists of mounting

the handle to the outside and the stiffener bracket to the inside of the enclo-

sure and securing with two bolts, as shown in the figure below.

Air Valve Interlocks

Air valve interl ocks are designed to inter lock specific three-way a ir valves with Class 9422 Type A1, 2,

5, 6, 7, 8, 9, or 10 handle mechanisms when mounted to the r ight-hand side of an enclosure. These

de vices mechanically interlock the air and electrical supplies of a machine so both can be disconnected

or padlock ed OFF simultaneously. The air valve interlock makes it possib le to exhaust the air in machine

lines when the handle mechanism is moved to the OFF position, making the machine both electr ically

and pneumatically inoperative.

Air valv e interlocks will only accept specific three-wa y air valv es manufactured by Shrader Bellows listed

in the table below. Note that the valves must be purchased directly from Shrader Bellows,

200 W. Exchange St., Akron, OH 44309-0631.

34 12/97

Class 9423 Do or-Closing Me chan is ms

Class 9423 door-closing mechanisms may be used on enclosures with door openings up to 91 inch es.

The door closing mechanisms are designed to be used on control enclosures and interlocked with a

Class 9422 disconnect device, although they all can be used independently . Three diff erent systems are

av ailable and their use is as recommended below. A complete system is av ailab le for interlocking all the

doors of a multi-door enclosure with the master door when using the 6" or 8" vault handle mechanism.

Note that the “Master Door” is d efined to be the door of a single or multi-door enclo sure w hich is inter-

lock ed directly with the disconnect device . The master door can be hinged on either the right or left hand

side. It can be located in a ny position on a multi-door en closure. The “Auxiliar y Door” is defined to be

the remaining door(s) of a multi-door enclosure which is (are) interlock ed with the master door by means

of the overhead interlo cking system as illustrated on the next two pages.

Selection Procedure

Step 1. Determine enclosure construction (number of doors, door height, hinge location, etc.).

Step 2. Determine Class 9422 disconnect device to be used – either a disconnect switch or a circuit

breaker mechanism (see examples of these de vices to the left).

Step 3. Deter mine the loca tion of disconnect device and handle mechanism (right- or left-han d flange or

center channel).

Step 4. Select the door closing mechanism required:

Step 5. Select auxiliary door closing mechanisms and multi-door interlocking hardware, if required. (A

complete system f or interlocking all auxiliary doors of a multi-door enclosure with center channel is

av ailab le for the medium and large enclosures.)
