Product Description

Siemens 8UC6114-1BB00 Front Drive Handle – For Superswitch 3KL81/3KA81

The Siemens 8UC6114-1BB00 is a Front Drive Handle accessory for Siemens Superswitch 3KL8/3KA8 switch-disconnector fuse devices. Siemens accessory documentation specifies this handle for the 3KL81 11/21/51/71 and 3KA81 51/71 families.

Important product-identification note: your supplied title says “3KL81 3KA82”, but Siemens documentation identifies 8UC6114-1BB00 with 3KL81 and 3KA81, not 3KA82. The 3KL82/3KA82 front-drive handle is 8UC6214-1BB00.

For SB Smart, the product should therefore be listed as Siemens 8UC6114-1BB00 Front Drive Handle for Superswitch 3KL81/3KA81.

Siemens 8UC6114-1BB00 Front Drive Handle

The 8UC6114-1BB00 belongs to the Siemens 8UC6 rotary operating mechanism accessory range used with Superswitch switch-disconnector fuse assemblies. Siemens identifies it as the Front Drive (Handle) for the smaller 3KL8/3KA8 current range.

The handle provides the front operating interface for a compatible Superswitch and allows manual operation of the switching mechanism from the front of the installation.

Compatible Superswitch Models

Siemens accessory documentation associates 8UC6114-1BB00 with:

• 3KL81 11

• 3KL81 21

• 3KL81 51

• 3KL81 71

• 3KA81 51

• 3KA81 71

The exact switch article should be checked before ordering to ensure the handle is mechanically compatible.

Front Operating Handle

The main function of the 8UC6114-1BB00 is to provide a front-mounted operating handle for the compatible Superswitch.

It allows an operator to manually operate the switch-disconnector from the front side of the panel, enclosure or switchgear assembly when used with the appropriate operating mechanism.

The handle itself is an operating accessory; the actual switching, isolation and fuse-protection functions are provided by the associated Superswitch.

8UC6 Rotary Operating Mechanism

The Siemens 8UC6 family provides rotary operating mechanisms for Superswitch devices. Siemens documentation notes features such as an integrated retractable locking device, door interlock functions and adjustable shafts for different panel depths.

The front handle forms part of this operating mechanism and is used with the corresponding coupler and operating shaft.

Operating Shaft Compatibility

For the 3KL81/3KA81 range, Siemens accessory information identifies the corresponding 300 mm operating shaft as 8UC60-31.

When replacing a complete front-drive arrangement, the handle and operating shaft should therefore be checked together.

Panel Door Operation

The front-drive arrangement is useful when the Superswitch is mounted behind a panel door or enclosure and front-side manual operation is required.

It can support:

• Convenient front-side switching

• Operator accessibility

• Enclosed switchgear applications

• Panel-mounted Superswitch installations

• Maintenance and replacement requirements

Exact mounting dimensions should be taken from the applicable Siemens installation documentation.

Suitable for Superswitch Installations

The 8UC6114-1BB00 is intended for compatible Siemens Superswitch installations where a front operating handle is required.

Typical applications include:

• Industrial switchboards

• Power-distribution panels

• Electrical control panels

• Feeder switching assemblies

• Superswitch installations

• Industrial machinery

• Electrical maintenance applications

Size-Specific Front Handle Selection

Siemens uses different front-drive handles for different Superswitch sizes:

This size-based selection is documented in Siemens' accessory range.

Difference from 8UC6214-1BB00

The 8UC6214-1BB00 is the front-drive handle for the 3KL82/3KA82 family, while 8UC6114-1BB00 is intended for the 3KL81/3KA81 family.

Therefore, the two articles should not be treated as interchangeable without checking the exact Superswitch model.

Difference from 8UC6314-1BB00

The 8UC6314-1BB00 is intended for the larger 3KL83/3KA83 family, while 8UC6114-1BB00 belongs to the 3KL81/3KA81 range.

Correct size matching is essential for mechanical compatibility.

Front Drive and Locking Function

The Siemens 8UC6 rotary operating mechanism includes an integrated locking arrangement and door-interlock functionality. This allows compatible front-drive assemblies to support controlled operation and panel-door interlocking according to the complete installation design.

The actual locking and interlocking behaviour depends on the complete 8UC6 assembly and installed Superswitch.

Replacement and Maintenance

The 8UC6114-1BB00 can be useful where an existing front-drive handle on a compatible 3KL81/3KA81 Superswitch is damaged, worn or missing.

Before ordering, verify:

• Exact Superswitch article

• 3KL81 or 3KA81 family

• Existing front-drive arrangement

• Operating shaft

• Panel-door arrangement

• Required handle configuration

This helps avoid selecting a handle intended for another Superswitch size.

Industrial Procurement Applications

The 8UC6114-1BB00 is relevant for:

• Electrical panel builders

• Switchgear assemblers

• Industrial buyers

• Electrical contractors

• Maintenance departments

• OEM equipment maintenance

• Electrical product dealers

• Replacement-part procurement

For SB Smart, the product is positioned as a Siemens industrial switchgear accessory for supply, replacement and procurement.

Standard Package Quantity

Siemens accessory documentation lists the front-drive handle articles with a standard package quantity of 1 unit.

This makes the article suitable for individual maintenance and replacement requirements.

Current SB Smart Listing

SB Smart currently lists 8UC6114-1BB00 as “3KL81 3KA82 Front Drive Handle.”

However, Siemens documentation identifies the compatible 3KA family as 3KA81, so the SB Smart title should ideally be corrected to avoid product-selection confusion.
