Product Description

Siemens 3KX8340-0AG Fuse Cover – 4-Pole DIN for Superswitch 3KL83/3KA83

The Siemens 3KX8340-0AG is a Fuse Cover accessory for the Siemens Superswitch 3KL8/3KA8 switch-disconnector range. The exact article is the 4-pole DIN fuse-cover version for compatible 3KL83/3KA83 switch-disconnectors. Siemens accessory documentation identifies 3KX8340-0AG as a Fuse Cover, not as an auxiliary switch.

Important product-identification note: the supplied title describes this SKU as an “Auxiliary switch (1NO+1NC)”, but Siemens documentation lists 3KX8340-0AG under Fuse Cover, 4P, DIN fuse. For the corresponding 3KL83/3KA83 family, the 1NO+1NC auxiliary switch is 3KX3552-1YC.

For SB Smart, the accurate product page should therefore identify 3KX8340-0AG as a Siemens Superswitch Fuse Cover rather than a 1NO+1NC auxiliary switch.

Siemens 3KX8340-0AG Fuse Cover

The 3KX8340-0AG belongs to the Siemens Superswitch 3KL8/3KA8 accessory range and is designed for the 3KL83/3KA83 family. Siemens lists this specific article under the Fuse Cover category for a 4-pole DIN fuse configuration.

The fuse cover is intended to provide the specified protective covering over the fuse area of the compatible switch-disconnector assembly.

4-Pole Configuration

The exact 3KX8340-0AG is the 4-pole fuse-cover version for the applicable 3KL83/3KA83 Superswitch family.

Siemens lists the 3KL83/3KA83 fuse-cover variants as:

• 3KX8340-0AF – 2P

• 3KX8340-0AE – 3P

• 3KX8340-0AG – 4P

The installed switch's pole configuration should therefore be checked before ordering.

DIN Fuse Configuration

The 3KX8340-0AG is specified for the DIN fuse configuration. Siemens' Superswitch accessory table distinguishes DIN and BS fuse-cover variants, with the 3KL83/3KA83 family using 3KX8340-0AG for the 4-pole DIN arrangement.

This makes exact fuse-system matching important when selecting the accessory.

Compatible Superswitch Family

The 3KX8340-0AG is associated with:

• 3KL83 series

• 3KA83 series

The Siemens accessory table includes the relevant 3KL83/3KA83 model groups under this fuse-cover article.

The exact switch-disconnector article should always be checked before procurement to confirm compatibility.

Fuse Cover Function

The primary function of the 3KX8340-0AG is to cover the fuse area of the compatible Superswitch.

A correctly installed fuse cover can help:

• Cover the fuse section

• Reduce accidental access to internal conductive parts

• Maintain the intended switchgear configuration

• Provide the specified accessory arrangement

• Support a cleaner and more protected electrical assembly

The actual protection level depends on the complete Siemens switch-disconnector and installation.

Superswitch Accessory

Siemens offers multiple accessories for the 3KL8/3KA8 Superswitch family, including:

• Fuse Covers

• Terminal Covers

• Phase Barriers

• Fuse Cover Phase Barrier Kits

• Auxiliary Switches

• Auxiliary Switch Covers

• Front Drives/Handles

The 3KX8340-0AG specifically belongs to the 4-pole DIN Fuse Cover category for the 3KL83/3KA83 range.

Correct 1NO + 1NC Auxiliary Switch

For accurate product identification, the 1NO + 1NC auxiliary switch for the same 3KL83/3KA83 family is 3KX3552-1YC.

Siemens lists the accessories separately:

• 3KX8340-0AG – Fuse Cover, 4P, DIN

• 3KX3552-1YC – Auxiliary Switch, 1NO+1NC

Therefore, the two articles should not be treated as interchangeable.

Difference from 3KX8341-0AG

The 3KX8340-0AG and 3KX8341-0AG are different accessories:

3KX8340-0AG: Fuse Cover, 4P, DIN fuse

3KX8341-0AG: Terminal Cover, 4P

Siemens' accessory documentation lists these as separate items for the same 3KL83/3KA83 family.

This distinction is important when selecting an exact replacement accessory.

Difference from 3KX8340-9AE

The 3KX8340-9AE is a Fuse Cover Phase Barrier Kit, whereas 3KX8340-0AG is specifically a 4-pole DIN Fuse Cover. Siemens lists both under separate accessory categories.

The required accessory should therefore be selected according to the intended function.

Industrial Electrical Applications

The 3KX8340-0AG can be relevant for compatible:

• Industrial switchboards

• Electrical distribution panels

• Superswitch assemblies

• Low-voltage power-distribution equipment

• Fuse switch-disconnector installations

• Industrial switchgear

• Electrical maintenance and replacement applications

It should only be installed with the specified compatible Siemens Superswitch.

Replacement Accessory

The 3KX8340-0AG can be useful when an existing 4-pole DIN fuse cover on a compatible 3KL83/3KA83 Superswitch is damaged, missing or requires replacement.

Before ordering, verify:

• Exact Superswitch model

• Number of poles

• Fuse system

• DIN or BS configuration

• Accessory article number

• Mechanical compatibility

Using the correct fuse-cover article is important because Siemens provides separate covers for different fuse systems and pole configurations.

Standardized Fuse-Cover Range

For the 3KL83/3KA83 family, Siemens lists:

• 3KX8340-0AF – 2P, DIN

• 3KX8340-0AE – 3P, DIN

• 3KX8340-0AG – 4P, DIN

The related BS fuse-cover variants are listed separately for applicable Superswitch sizes.

This makes article-number selection straightforward when the pole count and fuse type are known.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 3KX8340-0AG 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.
