The Siemens 3KX8340-9AE is a Fuse Cover Phase Barrier Kit designed for the Siemens Superswitch 3KL83/3KA83 switch-disconnector range. Siemens accessory documentation specifically identifies this article as a Fuse cover phase barrier kit, not as a standalone auxiliary switch.
Important product-identification note: the supplied product title describes 3KX8340-9AE as an Auxiliary switch (1NO+1NC), but Siemens documentation lists the exact article under Fuse cover phase barrier kit. The corresponding 1NO+1NC auxiliary switch for the 3KL83/3KA83 family is 3KX3552-1YC.
For SB Smart, the accurate product page should therefore identify 3KX8340-9AE as a Fuse Cover Phase Barrier Kit.
The 3KX8340-9AE belongs to the Siemens Superswitch 3KL8/3KA8 accessory range. It is specifically associated with the 3KL83/3KA83 family. Siemens' accessory table places it under Fuse cover phase barrier kit.
The kit combines the relevant fuse-cover and phase-barrier functions for the compatible Superswitch configuration.
The 3KX8340-9AE is specified for:
3KL83 series
3KA83 series
The Siemens accessory table shows 3KX8340-9AE in the 3KL83/3KA83 column, while the corresponding larger-family kit 3KX8440-9AE is specified for 3KL84/3KA84.
The exact Superswitch article should be checked before ordering to ensure mechanical compatibility.
The fuse-cover part of the kit provides a protective cover over the fuse area of the compatible switch-disconnector assembly.
A suitable fuse cover can help:
Cover the fuse section
Reduce accidental access to internal components
Maintain the intended Superswitch configuration
Support a cleaner switchgear assembly
Provide the specified accessory arrangement for the compatible device
The actual protection level depends on the complete Siemens assembly and installation.
The phase-barrier part provides physical separation between adjacent phases within the compatible Superswitch assembly.
It can help:
Separate adjacent conductive phases
Maintain the intended insulation arrangement
Support required electrical clearances
Reduce the possibility of unintended contact between adjacent phase components
The accessory should be installed according to the relevant Siemens assembly instructions.
Unlike a simple fuse cover or phase barrier supplied as a separate accessory, the 3KX8340-9AE is identified by Siemens as a combined Fuse cover phase barrier kit.
This makes it useful when the compatible Superswitch requires the combined accessory arrangement rather than an individual cover or barrier.
The 3KX8340-9AE and 3KX8343-0AE are different accessories:
3KX8340-9AE: Fuse cover phase barrier kit
3KX8343-0AE: Phase barrier
Both are associated with the 3KL83/3KA83 family, but their functions are different.
This distinction is important when selecting an exact replacement accessory.
The 1NO + 1NC auxiliary switch for the 3KL83/3KA83 family is 3KX3552-1YC. The Siemens accessory table lists this article separately from the 3KX8340-9AE kit.
Therefore, 3KX8340-9AE should not be marketed as an auxiliary switch unless a separate manufacturer source specifically confirms a different configuration.
The 3KX8340-9AE can be relevant for compatible:
Industrial switchboards
Electrical distribution panels
Superswitch assemblies
Low-voltage power-distribution equipment
Switch-disconnector installations
Fuse-protection assemblies
Electrical maintenance applications
Replacement accessory requirements
The accessory should only be used with the specified compatible Siemens switch-disconnector.
The 3KX8340-9AE can be useful where the existing fuse-cover/phase-barrier arrangement on a compatible 3KL83/3KA83 Superswitch is damaged, missing or requires replacement.
Before ordering, verify:
Exact Superswitch model
Switch family
Fuse configuration
Accessory function
Article number
Mechanical compatibility
Siemens uses different accessory numbers for different Superswitch sizes, so exact model matching is important.
The 3KL83/3KA83 accessory range includes:
3KX8340-0AF / 0AE / 0AG – Fuse Covers for different pole configurations
3KX8341-0AF / 0AE / 0AG – Terminal Covers
3KX8343-0AE – Phase Barrier
3KX8340-9AE – Fuse Cover Phase Barrier Kit
3KX3552-1YC – Auxiliary Switch, 1NO+1NC
3KX3552-1YD – Auxiliary Switch, 2NO+2NC
8UC6314-1BB00 – Front Drive (Handle)
This standardized accessory range helps select the correct component according to the required function.
Siemens accessory documentation lists the standard package quantity for 3KX8340-9AE as 1 piece.
This is suitable for individual replacement and maintenance procurement.
The Siemens 3KX8340-9AE is relevant for:
Electrical panel builders
Industrial buyers
Maintenance departments
Electrical contractors
Switchgear assemblers
Electrical product dealers
Replacement-part procurement
For SB Smart, the product is positioned around industrial electrical product supply and procurement, without claiming automation integration or automation-service work.
