The Siemens 3KX8343-0AE is a Phase Barrier accessory for the Siemens Superswitch 3KL8/3KA8 switch-disconnector range. Siemens accessory documentation identifies the exact article as a Phase Barrier for the 3KL83/3KA83 family and specifies it for DIN, BS and cylindrical fuse configurations.
Important product-identification note: the supplied title describes this SKU as an “Auxiliary switch (1NO+1NC)”, but Siemens documentation clearly lists 3KX8343-0AE as a Phase Barrier, not an auxiliary switch. The 1NO+1NC auxiliary switch for the corresponding 3KL83/3KA83 Superswitch family is 3KX3552-1YC.
For SB Smart, the accurate product page should therefore identify 3KX8343-0AE as a Phase Barrier accessory.
The 3KX8343-0AE belongs to the Siemens Superswitch accessory range and is designed for compatible 3KL83 and 3KA83 switch-disconnector configurations. Siemens documentation places this article specifically under the Phase Barrier category.
A phase barrier is used within a switch-disconnector assembly to provide separation between adjacent phases and help maintain the intended insulation and clearance arrangement.
The 3KX8343-0AE is specified for:
3KL831
3KL832
3KL833
3KL834
3KA831
3KA832
3KA834
3KA835
The Siemens accessory table associates the article with the 3KL83/3KA83 family.
The exact Superswitch article should always be checked before ordering to ensure mechanical compatibility.
The primary purpose of the 3KX8343-0AE is to provide a physical phase barrier within the compatible switch-disconnector assembly.
This can help:
Separate adjacent electrical phases
Maintain required insulating distances
Reduce the possibility of unintended contact between conductive parts
Support the intended internal arrangement of the switch-disconnector
Maintain the correct accessory configuration
The exact protective and insulation function depends on the complete Siemens assembly.
Siemens documentation specifies the 3KX8343-0AE under the DIN / BS / Cylindrical fuse category.
This means the phase barrier is associated with compatible Superswitch configurations using the relevant fuse-system arrangements.
The exact switch and fuse configuration should be checked before selecting the accessory.
The Siemens 3KL8/3KA8 accessory range includes multiple components such as:
Fuse covers
Terminal covers
Phase barriers
Fuse-cover phase-barrier kits
Auxiliary switches
Front drives and handles
The 3KX8343-0AE specifically belongs to the Phase Barrier category for the 3KL83/3KA83 range.
For clarity, the 1NO + 1NC auxiliary switch for the corresponding 3KL83/3KA83 Superswitch family is 3KX3552-1YC, not 3KX8343-0AE. Siemens accessory documentation lists these articles separately.
This distinction is important for accurate product cataloguing and SEO content on SB Smart.
The 3KX8343-0AE 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 and replacement applications
The accessory should only be installed with the specified compatible Siemens switch-disconnector.
The 3KX8343-0AE can be useful where a phase barrier on a compatible Superswitch is damaged, missing or requires replacement.
Before ordering, verify:
Exact Superswitch model
Switch family
Fuse configuration
Phase-barrier requirement
Accessory article number
Mechanical compatibility
Siemens provides different phase-barrier articles for different Superswitch sizes, so the correct article number is important.
The Siemens accessory table lists different phase barriers according to Superswitch size:
3KX8153-0AE – for 3KL81/3KA81 range
3KX8343-0AE – for 3KL83/3KA83 range
3KX8433-0AE – for 3KL84/3KA84 range
The 3KL82/3KA82 range uses separate DIN/BS variants listed in the Siemens accessory table.
Siemens price-list documentation lists the 3KX8343-0AE with a standard package quantity of 1 piece.
This makes it suitable for individual maintenance, replacement and switchgear-accessory procurement.
The Siemens 3KX8343-0AE 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.
