The Siemens 3NWNS4 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 4 A, 415 V AC, with an 80 kA breaking capacity, Size F1, GG operating class, and a blade tag configuration.
For SB Smart, this product is positioned as a Siemens industrial electrical protection component for supply, procurement, replacement and maintenance requirements.
The 3NWNS4 belongs to the Siemens 3NW BS HRC fuse range, designed for low-voltage circuit protection. Siemens-related documentation identifies the 3NW family 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 ratings, making it suitable for compatible industrial and electrical distribution applications.
The exact 3NWNS4 has a rated current of 4 A.
The 4 A rating should be selected according to the protected circuit, conductor capacity, equipment rating and the overall protection-coordination requirements.
The fuse should only be replaced with a device having compatible electrical and mechanical specifications.
The 3NWNS4 is rated for 415 V AC. The Siemens 3NW BS fuse family is also specified for 240 V DC applications where applicable.
The actual system voltage should always be verified before selecting or replacing the fuse.
The exact 3NWNS4 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.
The 3NWNS4 is identified as Size F1. Siemens-related product data for the exact article confirms the F1 physical size.
The physical fuse size must match the corresponding fuse base, holder or switch-fuse arrangement.
The 3NWNS4 uses a blade tag configuration. Product specifications and Siemens-related listings identify the exact article as a blade-tag fuse.
The tag configuration is an important mechanical-selection parameter because the fuse must correctly fit the corresponding holder or mounting arrangement.
The exact 3NWNS4 is specified as an operating class GG fuse.
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 means High Rupturing Capacity. An HRC fuse is designed to interrupt high fault currents safely within its specified breaking capacity.
The 3NWNS4 combines:
4 A rated current
415 V AC 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.
The 3NWNS4 is part of the Siemens 3NWNS blade-tag series, which includes other low-current variants such as 3NWNS2, 3NWNS6, 3NWNS10, 3NWNS16, 3NWNS20, 3NWNS25 and 3NWNS32.
This allows selection of different current ratings while retaining the applicable blade-tag configuration.
The 3NWNS4 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.
The 3NWNS4 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.
The 3NWNS4 is part of the Siemens 3NW blade-tag series. The 3NW documentation groups multiple low-current ratings under this configuration, making it useful for standardized fuse selection across compatible circuits.
Published Siemens-related pricing documentation lists a standard package quantity of 20 pieces for the 3NWNS4.
This is useful for stock planning, maintenance procurement and replacement requirements.
The Siemens 3NWNS4 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.
