The Siemens 3NWTIS50 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 product is rated at 50 A, 415 V AC, with an 80 kA breaking capacity, Size A3, GG operating class, and an offset tag configuration. Siemens-related product documentation identifies the 3NWTIS50 within the A3 offset-tag fuse group.
For SB Smart, this product is best positioned as a Siemens industrial electrical protection component for supply, procurement, replacement and maintenance requirements.
The 3NWTIS50 belongs to the Siemens 3NW BS HRC fuse range, developed for low-voltage circuit protection applications. Siemens documentation for the 3NW family specifies 415 V AC / 240 V DC operation and 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.
The exact 3NWTIS50 has a rated current of 50 A.
The 50 A rating should be selected according to the protected circuit, conductor capacity, equipment rating and overall protection-coordination requirements.
The fuse should only be replaced with a device having compatible electrical and mechanical specifications.
The 3NWTIS50 is rated for 415 V AC. Product specifications for the exact article confirm this rated voltage.
The actual system voltage should always be verified before selecting or replacing the fuse.
The exact 3NWTIS50 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 is useful in industrial and electrical distribution applications where the available fault current can be significant.
The 3NWTIS50 is identified as Size A3 in Siemens-related fuse-selection documentation. The 3NW TIS series includes the 40 A and 50 A variants in the A3 size group.
The physical fuse size must match the corresponding fuse base, holder or switch-fuse arrangement.
The 3NWTIS50 uses an offset tag configuration. Product listings specifically identify the exact model as an offset-tag HRC fuse.
The tag position is an important mechanical-selection parameter because the fuse must fit the corresponding holder or mounting arrangement.
The exact 3NWTIS50 is identified 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 3NWTIS50 combines:
50 A rated current
415 V AC rated voltage
80 kA breaking capacity
Size A3
Offset tag
GG operating class
These specifications make it suitable for compatible low-voltage industrial protection applications.
The 3NWTIS50 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 protection-coordination requirements.
The 3NWTIS50 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 3NWTIS50 is part of the Siemens 3NW TIS offset-tag range. Siemens-related fuse documentation lists 3NWTIS40, 3NWTIS50 and 3NWTIS63 in this offset-tag family, with the 40 A and 50 A versions associated with the A3 size group.
This helps customers select a matching current rating while retaining the required fuse format.
The Siemens 3NWTIS50 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.
