Non-Metallic Enclosures The VARIO Loadbreak Switch is also offered as an enclosed switch, which is made of corrosion resistant material suitable for IP55 environments. The 3-pole version makes the VARIO Loadbreak Switch ideal for manual motor control applications. They are compact, easy to wire and connect, and come undrilled to allow variable cable entry positions. Note that these enclosures do not pass the UL Burn Test, which means that these versions are not UL Listed.

The D10 accepts Class H, K, J, or R fuses -- or can be used for non-fusible applications. The D10 disconnect switch is operated by a cast metal handle operator that is lockable in the OFF position and defeatable in the ON position. 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 spring-loaded action throws the switch into the ON position under pressure. This provides a quick-break when switching to the OFF position. The double-break contact principle also assures longer life and exceptional interrupting 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 visible 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.

The master door can be hinged on either the right or left hand side. It can be located in any position on a multi-door enclosure. The "Auxiliary Door" is defined to be the remaining door(s) of a multi-door enclosure which is (are) interlocked with the master door by means of the overhead interlocking 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 devices to the left). Step 3.

Imperative in the enclosure design is the door depth, which must be 0.75" (19mm) as shown in Figure 1 regardless of whether a disconnect device is used. The figures are top views of the flange or center channels with various door configurations. Transpose all dimensions for enclosures with doors closing oppositely of those shown. Flange Construction Figure 1 Figure 1 shows flange construction. Dimension C is 3" (76mm) with a Type A5 or A7 handle on the enclosure flange. With a Class 9422 Type A1 handle mechanism on the enclosure flange, the minimum dimension for C is 1.75" (45mm); without a Class 9422 Type A1 handle mechanism on the enclosure flange, the minimum dimension for C is 0.69" (18mm). Channel Construction Figures 2 and 3 show the type of channel construction where two doors close on a common channel. In Figure 2, the dimensions apply when a Type M6 kit is used on each door regardless of whether a Class 9423 Type M2 auxiliary door interlock is utilized. In this particular type of construction, the minimum dimension for E is 2" (51mm) with a Class 9423 Type M2 interlock or 1.38" (36mm) without an M2 interlock. In Figure 3, the dimensions apply when a Class 9422 A1 handle, Class 9423 M5 kit, and Class 9423 M2 interlock are all located in the channel. Figure 2 Figure 4 shows the type of channel construction where one door closes on a common channel, while another door is hinged on the common channel. For this type of channel construction, the minimum dimension for E is 2.25" (58mm) with a Class 9422 A1 handle mechanism in the channel (with or without a Class 9423 M5 kit) or 1.25" (32mm) without an A1 handle. Additionally, the minimum for dimension D with this type of channel construction is 3.25" (83mm) with a Class 9422 A1 handle mechanism in the channel (with or without a Class 9423 M5 kit) or 2.25" (58mm) without an A1 handle.

Imperative in the enclosure design is the door depth, which must be 1.13" (29mm) as shown in Figure 1 regardless of whether a disconnect device is used. The figures are top views of the flange or center channels with various door configurations. Transpose all dimensions for enclosures with doors closing oppositely of those shown. Flange Construction Figure 1 Figure 1 shows flange construction. Dimension C is 3" (77mm) with a Type A5 or A7 handle on the enclosure flange. With a Class 9422 Type A1 handle mechanism on the enclosure flange, the minimum dimension for C is 3" (77mm); without a Class 9422 Type A1 handle mechanism on the enclosure flange, the minimum dimension for C is 1.5" (39mm). Channel Construction Figures 2 and 3 show the type of channel construction where two doors close on a common channel. In Figure 2, the dimensions apply when a Type M8 kit is used on each regardless of whether a Class 9423 Type M2 auxiliary door interlock is utilized. In Figure 3, the dimensions apply when a Class 9422 Type A1 handle, Class 9423 M1 kit, and a Class 9423 M2 interlock are all located on the channel. (For an alternate door closing method using a similar type of construction, refer to Class 9423 Type M25 on page 41.) Figure 2 Figure 4 shows the type of channel construction where one door closes on a common channel, while another door is hinged on the common channel. For this type of channel construction, the minimum dimension for E is 3" (77mm) with a Class 9422 A1 handle mechanism in the channel (with or without a Class 9423 M1 kit) or 2" (51mm) without an A1 handle. Additionally, the minimum for dimension D with this type of channel construction is 4" (102mm) with a Class 9422 A1 handle mechanism in the channel (with or without a Class 9423 M5 kit) or 3" (77mm) without an A1 handle.
