Product Description

Siemens 3NWNS16 HRC Fuse – 16A, 415V AC, Size F1, Blade Tag

The Siemens 3NWNS16 is a low-voltage HRC fuse (BS) from the Siemens 3NW series, designed for protection against overload and short-circuit conditions in compatible low-voltage electrical systems. The exact Siemens article is rated at 16 A, 415 V, 80 kA breaking capacity, Size F1, and GG operating class. Siemens lists the product as an active product, with a quantity unit of one piece.

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 3NWNS16 belongs to the Siemens 3NW BS HRC fuse range. The Siemens 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 excessive fault current within its specified ratings, making it suitable for compatible industrial electrical distribution and protection applications.

16 A Rated Current

The exact 3NWNS16 has a rated current of 16 A. Siemens and current product listings confirm the 16 A rating.

The 16 A rating should be selected according to the protected circuit, conductor capacity, equipment rating and the overall protection-coordination requirements.

415 V Rated Voltage

The 3NWNS16 is rated at 415 V. Current product specifications identify the exact article as a 415 V low-voltage HRC fuse.

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

80 kA Breaking Capacity

The exact 3NWNS16 has an 80 kA breaking capacity.

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

This characteristic is especially relevant for industrial distribution and electrical protection applications where fault levels can be significant.

Size F1

The 3NWNS16 is identified as Size F1 by Siemens.

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

When replacing an existing fuse, the physical dimensions and mounting configuration should therefore be checked along with the electrical specifications.

Blade Tag Configuration

The 3NWNS16 uses a blade tag configuration. Current product specifications specifically identify the tag type as Blade Tag, and Siemens' price-list documentation places 3NWNS16 in the blade-tag section.

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 exact 3NWNS16 is specified with operating class GG. Siemens' official product description identifies the article as a 16 A, 415 V, Size F1, 80 kA, GG fuse.

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

HRC Fuse Protection

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

The 3NWNS16 combines:

• 16 A rated current

• 415 V rated voltage

• 80 kA 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 3NWNS16 is part of the Siemens 3NWNS blade-tag series. Siemens' current pricing documentation lists the blade-tag range at 2 A, 4 A, 6 A, 10 A, 16 A, 20 A, 25 A and 32 A, with the corresponding 3NWNS article numbers.

This allows users to select the required current rating while retaining the applicable blade-tag configuration.

Suitable for Industrial Electrical Systems

The 3NWNS16 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 3NWNS16 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 3NWNS16 is part of the Siemens 3NW blade-tag series, providing a standardized range for different current requirements.

The same blade-tag family includes 3NWNS2, 3NWNS4, 3NWNS6, 3NWNS10, 3NWNS20, 3NWNS25 and 3NWNS32.

This can simplify replacement and spare-part procurement where compatible fuse holders are already installed.

Standard Package Quantity

Siemens' published 2025/2026 pricing documentation lists a standard package quantity of 20 pieces for 3NWNS16.

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

The Siemens 3NWNS16 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.
