Product Description

Siemens 3KX8345-4AC SS Enclosure for Superswitch 3KL83/3KA83 – 200A to 400A

The Siemens 3KX8345-4AC is a Sheet Steel (SS) enclosure accessory for the Siemens Superswitch 3KL8/3KA8 switch-disconnector range. It is intended for the 3KL83 and 3KA83 family and is suitable for devices with rated currents from 200 A to 400 A. Siemens documentation identifies this article as an SS Enclosure, not as an auxiliary switch.

Important product-identification note: the supplied title describes this SKU as “Auxiliary switch (1NO+1NC)”, but Siemens accessory documentation identifies 3KX8345-4AC as an SS Enclosure. The 1NO+1NC auxiliary switch for the relevant Superswitch family is a different accessory article.

For SB Smart, this product should therefore be listed as a Siemens Superswitch SS enclosure accessory rather than a 1NO+1NC auxiliary switch.

Siemens 3KX8345-4AC SS Enclosure

The 3KX8345-4AC belongs to the Siemens Superswitch 3KL8/3KA8 accessory range. Siemens accessory documentation places this enclosure under the SS Enclosure category for the 3KL83/3KA83 switch-disconnector family.

“SS” refers to Sheet Steel, and the enclosure is intended to provide a dedicated housing for the compatible switch-disconnector assembly.

Compatible Superswitch Models

The 3KX8345-4AC is specified for the:

• 3KL83 series

• 3KA83 series

The Siemens accessory table associates the article with 3KL831/832/833/834 and 3KA831/832/834/835 configurations.

The exact Superswitch article should be checked before ordering to ensure mechanical compatibility.

200A to 400A Current Range

Current Siemens product documentation identifies the 3KX8345-4AC enclosure for Superswitches rated from 200 A to 400 A.

This makes the enclosure appropriate for the corresponding medium-to-high current 3KL83/3KA83 switch-disconnector range.

The enclosure itself is a mechanical accessory; the electrical current rating belongs to the compatible switch-disconnector installed inside it.

Sheet Steel Construction

The product is identified as an SS Enclosure, where SS stands for Sheet Steel. Siemens' current price-list documentation explicitly uses this abbreviation.

A sheet-steel enclosure provides a structured housing around the compatible switch assembly and can be useful for industrial distribution-panel installations.

690 V AC Application

The Siemens selection table associates the enclosure range with Superswitch devices having an operating rating of 690 V AC, 50 Hz.

The actual voltage capability of the complete assembly is determined by the installed Superswitch and its applicable technical specifications.

Enclosure for Superswitch Assembly

The 3KX8345-4AC is intended to house the compatible Superswitch assembly.

The enclosure provides a dedicated physical housing for:

• Compatible 3KL83/3KA83 switch-disconnectors

• Front operating arrangement

• Internal switching equipment

• Associated fuse and connection components

The complete installation should follow Siemens mounting and operating instructions.

Open Top and Bottom

Siemens' current price-list documentation notes that the enclosures are open at both the top and bottom and that separate gland plates should be ordered.

This is important during panel planning because the enclosure alone does not provide the complete cable-entry arrangement.

Gland Plate and Gland Box Options

For the 3KX8345-4AC, Siemens lists compatible gland accessories:

• 3KX8345-4DC – Gland Box with 1 Gland Plate

• 3KX8345-4GC – Gland Plate

The accessory table associates these with the same 3KL83/3KA83 family.

This allows the installer to select the required cable-entry arrangement separately.

Standard Package Quantity

Siemens price-list documentation specifies a standard package quantity of 1 unit for the 3KX8345-4AC.

This is suitable for individual switchgear enclosure procurement and replacement requirements.

Industrial Applications

The 3KX8345-4AC can be considered for compatible applications such as:

• Industrial distribution panels

• Low-voltage switchboards

• Superswitch installations

• Power distribution assemblies

• Feeder switching applications

• Industrial electrical equipment

• Switch-disconnector enclosures

• Maintenance and replacement projects

Actual application should be based on the selected Superswitch, enclosure configuration and installation requirements.

Replacement and Maintenance

The 3KX8345-4AC can be useful where an existing sheet-steel enclosure for a compatible 3KL83/3KA83 Superswitch needs replacement.

Before ordering, verify:

• Exact Superswitch model

• Rated current

• Number of poles

• Enclosure type

• Front-drive arrangement

• Cable-entry requirements

• Required gland plate or gland box

Superswitch Accessory Range

Siemens provides different SS enclosure sizes for different Superswitch current ranges:

• 3KX8235-4AC – 20 A to 160 A

• 3KX8345-4AC – 200 A to 400 A

• 3KX8435-4AC – 500 A to 800 A

The current Siemens price list specifies these enclosure ranges and their standard package quantity as 1 unit.

This makes it easier to select an enclosure according to the installed Superswitch rating.

Auxiliary Switch Clarification

The supplied product title mentions Auxiliary switch (1NO+1NC), but that description does not match the Siemens documentation for 3KX8345-4AC.

Siemens accessory documentation places 3KX8345-4AC under SS Enclosure, while the auxiliary-switch function is listed separately in the Superswitch accessory range.

Therefore, for accurate SB Smart product data, this SKU should not be described as a 1NO+1NC auxiliary switch unless a separate Siemens source confirms that specific configuration.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 3KX8345-4AC 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.
