The Siemens 3NWTSDC80 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 80 A, 415 V AC, with an 80 kA breaking capacity, Size B1, GG operating class, and a central tag configuration.
For SB Smart, this product is best positioned as a Siemens industrial electrical protection component for supply, procurement, replacement and maintenance requirements.
The 3NWTSDC80 belongs to the Siemens 3NW BS HRC fuse range, designed for low-voltage circuit protection applications. Siemens 3NW documentation specifies the range for 415 V AC / 240 V DC systems with an 80 kA AC breaking capacity.
The HRC 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 3NWTSDC80 has a rated current of 80 A.
The 80 A rating should be selected according to the protected circuit, conductor capacity, equipment rating and the overall protection-coordination requirements.
The 3NWTSDC80 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 fuse provides an 80 kA breaking capacity.
A high breaking capacity enables the HRC fuse to interrupt high prospective short-circuit currents within its specified operating conditions, which is important for industrial and electrical distribution systems.
The 3NWTSDC80 is identified as Size B1 in Siemens-related technical product data.
The physical fuse size must match the associated fuse base, holder or switch-fuse arrangement. For replacement applications, the existing fuse dimensions and mounting configuration should therefore be checked.
The 3NWTSDC80 uses a central tag configuration. Siemens' published 3NW documentation lists 3NWTSDC80 in the central-tag range.
The tag configuration is an important mechanical-selection parameter because the fuse must fit the corresponding holder or mounting arrangement.
The exact 3NWTSDC80 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 3NWTSDC80 combines:
80 A rated current
415 V AC rated voltage
80 kA breaking capacity
Size B1
Central tag
GG operating class
These specifications make it suitable for compatible low-voltage industrial protection applications.
Technical documentation for the Siemens 3NW series lists the 3NWTSDC80 with approximately 7.2 W rated power dissipation.
This value can be useful when considering heat generation and thermal conditions inside enclosed electrical panels.
The 3NWTSDC80 can be considered for compatible applications such as:
Industrial distribution panels
Feeder circuits
Electrical distribution systems
Industrial power panels
Machinery protection
Commercial electrical installations
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 3NWTSDC80 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 3NWTSDC80 is part of the Siemens 3NW central-tag range. Siemens documentation also lists a 100 A central-tag variant, 3NWTSDC100, followed by higher-current central-tag fuse types such as 3NWTSF125 and 3NWTSF160.
This range structure can help customers select a matching fuse according to current rating and physical configuration.
The Siemens 3NWTSDC80 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.
