Product Description

Siemens 3NW60021 Cylindrical Fuse – 2A, 500V AC, 10 × 38 mm, gG

The Siemens 3NW60021 is a SENTRON cylindrical fuse link designed for low-voltage electrical protection applications. The exact article is rated at 2 A, 500 V AC, uses a 10 × 38 mm cylindrical format and has a gG operating class. Siemens currently lists the corresponding market-facing number 3NW6002-1 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 3NW60021 Cylindrical Fuse

The 3NW60021 belongs to the Siemens SENTRON 3NW cylindrical fuse-link range. Siemens describes the 3NW cylindrical fuse system for selective line protection, with compatible cylindrical fuse links and holders suitable for industrial plants.

The fuse link provides protection against excessive current resulting from overload and short-circuit conditions within its specified electrical characteristics.

2 A Rated Current

The exact 3NW60021 has a rated current of 2 A. Siemens' official datasheet confirms the 2 A operating current rating.

The 2 A rating should be selected according to the protected circuit, conductor capacity, equipment requirements and the overall protection-coordination design.

500 V AC Rated Voltage

The 3NW60021 is rated for 500 V AC. Siemens' current Industry Mall description identifies the corresponding 3NW6002-1 as a 10 × 38 mm, 2 A, gG cylindrical fuse with 500 V AC rated voltage.

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

100 kA Breaking Capacity

Siemens' product data identifies the 3NW60021 with a 100 kA breaking capacity.

A high breaking capacity allows the fuse to interrupt substantial prospective fault currents within its specified operating conditions.

This characteristic can be important in industrial electrical distribution systems where available fault current may be significant.

10 × 38 mm Fuse Size

The exact 3NW60021 uses a 10 × 38 mm cylindrical fuse format. Siemens' official technical data confirms this physical size.

The fuse dimensions must match the corresponding fuse holder or fuse-disconnector arrangement.

For replacement applications, both physical dimensions and electrical ratings should be checked.

gG Operating Class

The 3NW60021 has a gG operating class. Siemens identifies the product as a gG cylindrical fuse link.

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 a solution for selective line protection in industrial plants.

The 3NW60021 can therefore be used in compatible electrical distribution and protection arrangements where coordinated fuse protection is required.

No Striker

The official Siemens datasheet specifies that the 3NW60021 has no striker.

This means the fuse does not include a striker mechanism for mechanically actuating a separate indication or switching mechanism.

Mounting Position

Siemens specifies the mounting position for the 3NW60021 as any position, preferably vertical.

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

Power Dissipation

Siemens' official datasheet lists approximately 0.5 W power loss for the 3NW60021 and approximately 1 W at rated current in hot operating condition per pole.

These values can be useful when evaluating 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 8 g.

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

Suitable for Industrial Electrical Systems

The 3NW60021 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 3NW60021 can be used as a replacement where the existing fuse requires compatible:

• Rated current

• Rated voltage

• Breaking capacity

• 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 3NW60021 is a 10 × 38 mm cylindrical fuse, the corresponding fuse holder must be designed for the same physical format and suitable electrical rating.

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

Standardized Siemens SENTRON Solution

The 3NW60021 is part of the Siemens SENTRON cylindrical fuse-link family. Siemens lists the corresponding market-facing article 3NW6002-1 in the Cylindrical Fuse Links and Cylindrical Fuse Holders product family.

This makes the article relevant for standardized cylindrical-fuse protection and replacement applications.

Active Product and Ordering Information

Siemens currently lists 3NW6002-1, corresponding to the 3NW60021 article designation, as PLM PM300: Active Product. The Industry Mall lists a quantity unit of 1 piece, packaging quantity of 1, and minimum order quantity of 10 pieces.

This distinction is useful when purchasing because the product is identified individually, while the commercial minimum order quantity is 10 pieces in the referenced Siemens Industry Mall listing.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 3NW60021 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.
