Product Description

Siemens 3NWNS25 HRC Fuse – 25A, 415V AC, Size F1, Blade Tag

The Siemens 3NWNS25 is a low-voltage HRC fuse (BS) from the Siemens 3NW series, designed for overload and short-circuit protection in compatible low-voltage electrical systems. The exact article is rated at 25 A, 415 V AC, with an 80 kA AC breaking capacity, Size F1, GG operating class, and a blade tag configuration. Siemens pricing documentation lists 3NWNS25 in the blade-tag range with a standard package quantity of 20 pieces.

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

Siemens 3NW HRC Fuse

The 3NWNS25 belongs to the Siemens 3NW BS HRC fuse range, which covers low-voltage HRC fuse links with ratings from 2 A to 800 A. The 3NW family is specified for 415 V AC / 240 V DC applications with an 80 kA AC breaking capacity.

The fuse is designed to interrupt overload and short-circuit currents within its specified electrical ratings, making it suitable for compatible industrial and electrical distribution applications.

25 A Rated Current

The exact 3NWNS25 has a rated current of 25 A. Siemens pricing documentation specifically lists the 25 A article under the blade-tag series.

The 25 A rating should be selected according to the protected circuit, conductor capacity, equipment requirements and overall protection-coordination requirements.

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

415 V AC Rated Voltage

The 3NWNS25 is rated for 415 V AC. The Siemens 3NW BS fuse family is specified for 415 V AC / 240 V DC applications.

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

80 kA Breaking Capacity

The 3NW series has an 80 kA AC breaking capacity, including the 3NWNS blade-tag range.

A high breaking capacity allows a suitable HRC fuse to interrupt high prospective short-circuit currents within its specified operating conditions.

Size F1

The 3NWNS25 is identified as Size F1 in Siemens-related product information for the blade-tag 3NWNS family. The 3NWNS series is the blade-tag group covering the low-current variants.

The physical fuse size must match the corresponding fuse base, holder or switch-fuse arrangement.

For replacement applications, the existing fuse size and mounting configuration should therefore be checked along with the electrical ratings.

Blade Tag Configuration

The 3NWNS25 uses a blade tag configuration. Siemens places 3NWNS25 specifically within the Blade tag section of the 3NW BS fuse range.

The tag configuration is an important mechanical-selection parameter because the fuse must correctly fit the corresponding holder or mounting arrangement.

GG Operating Class

The 3NWNS25 is a GG operating-class fuse. Siemens-related product information for the 3NWNS range identifies the family as low-voltage HRC fuses for general-purpose protection.

GG fuses are intended for general-purpose protection against overload and short-circuit conditions in compatible electrical circuits.

The correct fuse should still be selected according to the load, equipment rating, fault level and protection-coordination requirements.

HRC Fuse Protection

HRC means High Rupturing Capacity. An HRC fuse is designed to interrupt high fault currents safely within its specified breaking capacity.

The 3NWNS25 combines:

• 25 A rated current

• 415 V AC rated voltage

• 80 kA AC breaking capacity

• Size F1

• Blade tag

• GG operating class

These specifications make it suitable for compatible low-voltage industrial protection applications.

Low-Current Industrial Fuse Application

The 3NWNS25 is part of the Siemens 3NWNS blade-tag series. Siemens documentation lists the following blade-tag variants:

• 3NWNS2 – 2 A

• 3NWNS4 – 4 A

• 3NWNS6 – 6 A

• 3NWNS10 – 10 A

• 3NWNS16 – 16 A

• 3NWNS20 – 20 A

• 3NWNS25 – 25 A

• 3NWNS32 – 32 A

All are listed as blade-tag products, with a standard package quantity of 20 pieces.

This provides a standardized range for selecting different current ratings while maintaining the applicable blade-tag configuration.

Suitable for Industrial Electrical Systems

The 3NWNS25 can be considered for compatible applications such as:

• Industrial electrical panels

• Feeder protection

• Low-voltage distribution

• Electrical equipment protection

• Machinery protection

• Control-panel circuits

• Compatible BS HRC fuse assemblies

• Replacement of matching HRC fuse links

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

Fuse Replacement Applications

The 3NWNS25 can be used as a replacement where the existing fuse requires compatible:

• Rated current

• Rated voltage

• Breaking capacity

• Fuse size

• Tag configuration

• Operating class

A replacement fuse should not be selected solely because the ampere rating is the same. Mechanical compatibility with the fuse holder is equally important.

Standardized Siemens Fuse Solution

The 3NWNS25 is part of the Siemens 3NW blade-tag series, making it suitable for standardized procurement where compatible fuse holders and mounting arrangements are already in use.

The availability of multiple current ratings in the same series can help simplify replacement and stock management.

Standard Package Quantity

Siemens pricing documentation lists the standard package quantity for 3NWNS25 as 20 pieces.

This is useful for:

• Maintenance stock

• Panel-building procurement

• Replacement requirements

• Electrical contractors

• Industrial buyers

• Spare-part inventory

Suitable for Electrical Panel Builders and Industrial Buyers
