The Siemens 3KX8430-0AC is a fuse cover accessory for the Siemens Superswitch 3KL8/3KA8 range. It is designed for compatible 3KL841/842/843 and 3KA843/844/845/846 switch-disconnector configurations. Siemens product documentation identifies 3KX8430-0AC specifically as a Fuse Cover, not as an auxiliary switch.
Important product-identification note: the supplied title describes this SKU as “Auxiliary switch (1NO+1NC)”, but Siemens documentation consistently identifies 3KX8430-0AC as a Fuse Cover. The 1NO+1NC auxiliary switch for the corresponding 3KL84/3KA84 range is 3KX3582-1YC.
For SB Smart, the accurate product page should therefore identify 3KX8430-0AC as a Fuse Cover accessory and not as a 1NO+1NC auxiliary switch.
The 3KX8430-0AC belongs to the Siemens Superswitch accessory range for larger 3KL8/3KA8 switch-disconnector sizes. Siemens' accessory documentation places it in the Fuse Cover category for the 3KL841/842/843 and 3KA843/844/845/846 series.
The accessory is used to provide the appropriate protective cover for the fuse area of the compatible switch-disconnector assembly.
The 3KX8430-0AC is specified for:
3KL841
3KL842
3KL843
3KA843
3KA844
3KA845
3KA846
These compatibility references are given in Siemens accessory documentation.
The exact switch-disconnector article should always be checked before ordering the accessory.
The primary purpose of the 3KX8430-0AC is to cover and protect the fuse section of a compatible Superswitch assembly.
A suitable fuse cover can help:
Enclose the fuse area
Reduce accidental contact with internal components
Provide the required mechanical protection
Maintain the intended assembly configuration
Support panel safety and finishing requirements
The exact protective function depends on the complete switch-disconnector installation.
The Siemens 3KL8/3KA8 Superswitch accessory range includes several components for different switch sizes and installation requirements.
For the larger 3KL84/3KA84 range, Siemens lists:
3KX8430-0AC – Fuse Cover
3KX8431-0AC – Terminal Cover
3KX8432-0AC – Isolable Neutral Cover
3KX8433-0AC – Phase Barrier
3KX3582-1YC – Auxiliary Switch, 1NO+1NC
3KX3582-1YD – Auxiliary Switch, 2NO+2NC
8UC6414-1BB00 – Front Drive (Handle)
This makes it easier to select the correct accessory according to the required function.
For clarity, the 1NO + 1NC auxiliary switch associated with the larger 3KL84/3KA843/844/845/846 Superswitch range is 3KX3582-1YC, not 3KX8430-0AC. Siemens' accessory table explicitly lists 3KX3582-1YC under Auxiliary Switch (1NO+1NC) for these switch families.
This distinction is important for accurate product cataloguing and SEO.
The 3KX8430-0AC can be relevant for compatible:
Industrial switchboards
Electrical distribution panels
Superswitch assemblies
Low-voltage power-distribution equipment
Switch-disconnector installations
Electrical maintenance and replacement applications
The accessory should be installed only with its specified compatible Siemens switch-disconnector.
The 3KX8430-0AC can be useful where the existing fuse cover on a compatible Superswitch has been damaged, lost or requires replacement.
Before ordering, verify:
Exact Superswitch model
Number of poles
Switch-disconnector series
Fuse configuration
Accessory article number
Mechanical compatibility
Using the correct cover is important because Siemens provides different fuse covers for different Superswitch sizes.
Siemens uses different fuse-cover articles for different Superswitch sizes. The accessory table identifies:
3KX8150-0AC for the smaller 3KL81/3KA815 range
3KX8230-0AC for the 3KL82/3KA821/822/823 range
3KX8340-0AC for the 3KL83/3KA831/832/834/835 range
3KX8430-0AC for the 3KL84/3KA843/844/845/846 range
This size-based accessory structure helps simplify replacement selection.
Siemens accessory documentation lists the standard package quantity for 3KX8430-0AC as 1 piece.
This is suitable for individual maintenance and replacement procurement.
The Siemens 3KX8430-0AC is relevant for:
Electrical panel builders
Industrial buyers
Maintenance departments
Electrical contractors
Electrical product dealers
Switchgear maintenance teams
Replacement-part procurement
For SB Smart, the product should be positioned around industrial electrical product supply and procurement, without claiming automation integration or automation-service work.
