Product Description

Siemens 3NWCM32F9 Fuse Holder – 32A, 660V AC, Size A2 for 3NW TIA, TSA, TIS, TSS and TSDS Fuses

The Siemens 3NWCM32F9 is a BS-type fuse holder designed for compatible Siemens 3NW cylindrical HRC fuse links. It is rated at 32 A and is specified for Size A2 applications. Siemens documentation identifies this fuse holder for 3NW TIA, TSA, TIS, TSS and TSDS fuse types. Current product specifications also identify a 660 V AC rating.

For SB Smart, this product is best positioned as a Siemens industrial electrical accessory for fuse protection, panel maintenance, replacement and procurement requirements.

Siemens 3NWCM32F9 Fuse Holder

The 3NWCM32F9 belongs to the Siemens 3NW fuse-holder and accessory range. Its purpose is to provide the mechanical mounting and electrical connection required for compatible 3NW cylindrical fuse links.

Siemens documentation groups this holder with the 3NW TIA, TSA, TIS, TSS and TSDS fuse families.

This makes the 3NWCM32F9 suitable for electrical panels and other compatible low-voltage fuse-protection assemblies.

32 A Rated Current

The exact 3NWCM32F9 has a rated current of 32 A. Siemens-related product specifications and current distributor listings confirm the 32 A rating.

The holder rating should be considered together with the selected fuse link and the complete electrical installation.

The actual fuse must also be selected according to its current rating, voltage rating, breaking capacity and physical configuration.

660 V AC Rating

Current product specifications identify the 3NWCM32F9 as a 660 V AC fuse holder.

The complete protection assembly must be selected according to the actual system voltage and the ratings of both the holder and fuse link.

Size A2

The 3NWCM32F9 is identified as a Size A2 fuse holder.

The A2 designation is important because the physical dimensions of the compatible fuse must correspond to the holder.

A replacement holder should therefore be selected based on both the electrical rating and physical fuse format.

Compatible 3NW Fuse Types

The 3NWCM32F9 is specifically intended for the following Siemens 3NW fuse families:

• 3NW TIA

• 3NW TSA

• 3NW TIS

• 3NW TSS

• 3NW TSDS

This compatibility is explicitly identified in Siemens documentation and current product listings.

The exact fuse article should be checked before installation to confirm the required physical and electrical compatibility.

Fuse Holder for Cylindrical HRC Fuses

The 3NWCM32F9 is used with compatible cylindrical Siemens 3NW HRC fuse links.

The holder itself does not provide the overcurrent protection. The fuse link installed in the holder performs the protection function, while the holder provides the mounting and electrical connection.

This means the correct combination of fuse and holder is important for reliable operation.

BS-Type Fuse Holder

The 3NWCM32F9 is identified as a BS-type fuse holder for the compatible 3NW fuse families. Current product listings describe it specifically as a 32 A, 660 V AC, Size A2 holder for the listed Siemens 3NW fuse links.

The correct BS fuse-link type and physical configuration should be verified before purchase.

Electrical and Mechanical Connection

A suitable fuse holder provides two essential functions:

Mechanical mounting:
It holds the compatible fuse securely in the specified position.

Electrical connection:
It provides the connection between the fuse link and the electrical circuit.

The 3NWCM32F9 is designed to provide these functions for the compatible Siemens 3NW fuse families.

Industrial Fuse Protection Applications

The 3NWCM32F9 can be used in compatible:

• Industrial electrical panels

• Low-voltage distribution systems

• Feeder protection assemblies

• Control panels

• Electrical equipment

• Machinery protection systems

• Fuse replacement applications

• Industrial maintenance installations

Actual use should be based on the complete electrical protection design and the ratings of the selected fuse link.

Fuse Replacement and Maintenance

The 3NWCM32F9 is useful when an existing compatible fuse holder needs replacement or when a new panel requires a dedicated holder for Siemens 3NW cylindrical fuse links.

Before replacing an existing holder, verify:

• Fuse family

• Rated current

• Voltage rating

• Fuse size

• Physical configuration

• Terminal arrangement

• Compatibility with the selected fuse
