Product Description

Siemens 3NWTSS40 HRC Fuse – 40A, 415V AC, Size A3, Offset Tag

The Siemens 3NWTSS40 is a low-voltage HRC fuse (BS) from the Siemens 3NW series, designed to provide protection against overload and short-circuit conditions in compatible low-voltage electrical systems. The exact product is rated at 40 A, 415 V AC, with an 80 kA breaking capacity, Size A3, GG operating class, and an offset tag configuration.

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

Siemens 3NW HRC Fuse

The 3NWTSS40 belongs to the Siemens 3NW HRC fuse range for low-voltage electrical protection. The 3NW BS fuse family is specified for 415 V AC / 240 V DC systems with an 80 kA AC breaking capacity across the range.

The fuse is designed to interrupt excessive fault current within its specified ratings, making it suitable for compatible industrial and electrical distribution applications.

40 A Rated Current

The exact 3NWTSS40 has a rated current of 40 A.

The 40 A rating should be matched with the protected circuit, conductor capacity, equipment rating and the overall protection-coordination requirements.

Using a fuse with the correct current rating is essential for dependable circuit protection.

415 V AC Rated Voltage

The 3NWTSS40 is rated for 415 V AC. Siemens' 3NW BS fuse range is specified at 415 V AC / 240 V DC.

This makes it suitable for compatible low-voltage AC distribution and industrial electrical systems operating within the specified voltage rating.

80 kA Breaking Capacity

The 3NWTSS40 has an 80 kA breaking capacity.

A high breaking capacity allows the fuse to interrupt high prospective short-circuit currents within its specified operating limits. This characteristic is important in installations where available fault current may be high.

Size A3

The exact 3NWTSS40 is identified as Size A3.

The physical size is important when selecting the corresponding fuse holder, fuse base or switch-fuse arrangement.

The replacement fuse should always match the original fuse's physical size and mounting configuration.

Offset Tag Configuration

The 3NWTSS40 uses an offset tag configuration. Siemens price-list information places the 40 A article in the offset-tag 3NWTSS group.

The tag arrangement determines how the fuse link fits into its corresponding holder or mounting system.

Therefore, the tag type should be verified before replacing an existing fuse.

GG Operating Class

The 3NWTSS40 is identified with operating class GG.

A GG fuse is intended for general-purpose protection against overload and short-circuit conditions in compatible electrical circuits.

The fuse still needs to be selected according to the characteristics of the protected equipment and the application.

High Rupturing Capacity Protection

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

The 3NWTSS40 combines:

• 40 A rated current

• 415 V AC rated voltage

• 80 kA breaking capacity

• GG operating class

• Size A3

• Offset-tag construction

These characteristics make it suitable for compatible low-voltage electrical protection applications.

Suitable for Industrial Electrical Systems

The 3NWTSS40 can be considered for compatible applications such as:

• Industrial distribution panels

• Electrical feeder circuits

• Control panels

• Low-voltage distribution systems

• Machinery protection

• Commercial electrical installations

• Industrial replacement applications

• Compatible fuse-holder assemblies

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

Fuse Replacement Applications

The 3NWTSS40 can be used when replacing an existing fuse with the same electrical and physical requirements.

Before replacement, verify:

• Rated current

• Rated voltage

• Breaking capacity

• Fuse size

• Tag type

• Operating class

• Fuse-holder compatibility

A fuse should not be replaced solely on the basis of the same ampere rating.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 3NWTSS40 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 should be positioned around industrial electrical product supply and procurement, without claiming automation integration or automation-service work.
