Product Description

Siemens 3NW60071 Cylindrical Fuse – 20A, 500V AC, 10 × 38 mm, gG

The Siemens 3NW60071 is a SENTRON cylindrical fuse link designed for low-voltage electrical protection applications. The exact article has a 20 A rated current, 500 V AC rated voltage, 10 × 38 mm cylindrical fuse size, and gG operating class. Siemens currently lists the corresponding market-facing article 3NW6007-1 as an active product.

For SB Smart, this product is positioned as a Siemens industrial electrical protection component for supply, procurement, replacement and maintenance requirements.

Siemens 3NW60071 Cylindrical Fuse

The 3NW60071 belongs to the Siemens SENTRON 3NW cylindrical fuse-link range. Siemens describes this cylindrical fuse system as suitable for selective line protection and industrial plants. Siemens also notes that its cylindrical fuse links and holders are tested as fuse-disconnector systems and are not intended for switching under load.

The fuse link is intended to provide protection against overload and short-circuit conditions within its specified electrical ratings.

20 A Rated Current

The exact 3NW60071 has a rated current of 20 A. Siemens' official product data confirms the 20 A rating.

The 20 A rating should be selected according to the protected circuit, conductor capacity, equipment requirements and overall protection-coordination design.

The fuse should only be replaced with a device having compatible electrical and mechanical specifications.

500 V AC Rated Voltage

The 3NW60071 is rated for 500 V AC. Siemens' Industry Mall describes the corresponding article as a 10 × 38 mm, 20 A, gG cylindrical fuse with Un AC: 500 V.

The actual system voltage should always be verified before selecting or replacing the fuse.

10 × 38 mm Fuse Size

The exact 3NW60071 uses a 10 × 38 mm cylindrical fuse format. Siemens' official datasheet confirms this physical size.

The fuse dimensions must match the corresponding fuse holder or fuse-disconnector arrangement. For replacement applications, both the physical size and electrical ratings should be checked.

gG Operating Class

The 3NW60071 has a gG operating class. Siemens identifies the exact product as a cylindrical fuse link with gG characteristics.

The gG category is intended for general-purpose protection against overload and short-circuit conditions in suitable electrical circuits.

The final fuse selection should still be based on the load characteristics and protection requirements of the installation.

Cylindrical Fuse for Selective Line Protection

Siemens describes the 3NW cylindrical fuse system as suitable for selective line protection in industrial plants.

This makes the 3NW60071 relevant for industrial distribution and circuit-protection applications where coordinated protection is required.

No Striker

The official Siemens datasheet specifies that the 3NW60071 has no striker.

This means the fuse does not incorporate a striker mechanism for operating an external indicator or associated mechanical switching function.

Mounting Position

Siemens specifies the mounting position for the 3NW60071 as any position, preferably vertical.

Installation should also follow the recommendations of the selected fuse holder and electrical assembly.

Power Dissipation

Siemens' current datasheet lists approximately 2.4 W power loss for the product and specifies the corresponding thermal power-loss data for operation at rated current.

This information can be useful when considering heat generation and thermal conditions inside enclosed electrical panels.

Compact Cylindrical Fuse Design

The 10 × 38 mm format provides a compact fuse solution for compatible electrical protection assemblies.

Siemens lists the product with an approximate net weight of 9 g.

Its compact construction can be useful in space-conscious electrical panels and distribution assemblies.

Suitable for Industrial Electrical Systems

The 3NW60071 can be considered for compatible applications such as:

• Industrial electrical panels

• Low-voltage distribution

• Selective line protection

• Feeder protection

• Electrical equipment protection

• Machinery protection

• Industrial control panels

• Fuse replacement applications

Actual application should be based on system voltage, load current, prospective short-circuit current and the complete protection design.

Fuse Replacement Applications

The 3NW60071 can be used as a replacement where the existing fuse requires compatible:

• Rated current

• Rated voltage

• Fuse size

• Operating class

• Fuse-holder compatibility

A replacement fuse should not be selected solely because the current rating is the same. Physical dimensions and voltage rating must also match.

Compatible Fuse Holder Selection

Because the 3NW60071 is a 10 × 38 mm cylindrical fuse, the corresponding fuse holder must be suitable for this physical format and the applicable electrical rating.

Siemens' 3NW cylindrical-fuse system includes compatible fuse holders and fuse-disconnector solutions.

Standardized Siemens SENTRON Solution

The 3NW60071 is part of the Siemens SENTRON cylindrical fuse-link family and is listed in the Siemens Cylindrical Fuse Links and Cylindrical Fuse Holders product family.

The corresponding Siemens market-facing number is 3NW6007-1, while 3NW60071 is used as the product article designation in Siemens technical documentation.

Active Product and Ordering Information

Siemens currently lists 3NW6007-1 as PLM PM300: Active Product. The Industry Mall shows a quantity unit of 1 piece, packaging quantity of 1, and a minimum order quantity of 20 pieces.

This distinction is useful when purchasing: the article is identified individually, while the commercial minimum order quantity is listed as 20 pieces in Siemens' current Industry Mall data.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 3NW60071 is relevant for:

• Electrical panel builders

• Industrial buyers

• Maintenance departments

• Electrical contractors

• OEM equipment maintenance

• 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.
