Product Description

Siemens 3NWTSS63 HRC Fuse – 63A, 415V AC, Size A3, Offset Tag

The Siemens 3NWTSS63 is a low-voltage HRC fuse (BS) from the Siemens 3NW series, designed for reliable protection against overload and short-circuit conditions in low-voltage electrical systems. This fuse has a 63 A rated current, 415 V AC rated voltage, 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 product for supply, procurement, replacement and maintenance requirements.

Siemens 3NW HRC Fuse

The 3NWTSS63 belongs to the Siemens 3NW HRC fuse range designed for low-voltage electrical protection. Siemens 3NW BS fuse products are available in a wide current range and are designed for high short-circuit interruption capability. Product listings for the 3NWTSS63 identify it as a BS-type low-voltage HRC fuse with an 80 kA breaking capacity.

The fuse is suitable for applications where dependable short-circuit and overload protection is required in electrical distribution and industrial installations.

63 A Rated Current

The 3NWTSS63 has a rated current of 63 A.

The fuse selection should always be based on the rated current of the protected circuit, conductor capacity, equipment requirements and the complete protection-coordination design.

415 V AC Rated Voltage

The exact 3NWTSS63 is rated for 415 V AC.

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

80 kA Breaking Capacity

The fuse provides an 80 kA breaking capacity.

A high breaking capacity allows a suitable fuse to interrupt high prospective fault currents within its specified ratings, making this type of HRC fuse useful in industrial and power-distribution applications where short-circuit levels can be significant.

Size A3

The 3NWTSS63 is identified as Size A3.

The physical fuse size and tag configuration are important when selecting the correct fuse holder, base or switch-fuse arrangement.

Before replacement, the existing fuse dimensions and mounting arrangement should be checked to ensure compatibility.

Offset Tag Configuration

The 3NWTSS63 uses an offset tag configuration.

The tag arrangement determines how the fuse link fits into the corresponding fuse holder or fuse carrier.

This makes accurate tag-type selection important when replacing an existing fuse link.

GG Operating Class

The exact product is described as having operating class GG.

GG fuses are commonly used for general-purpose protection of electrical circuits and equipment against overload and short-circuit conditions.

The selected fuse must still be matched correctly to the circuit, equipment and protection requirements.

HRC Fuse Protection

HRC stands for High Rupturing Capacity. The purpose of an HRC fuse is to interrupt excessive fault current safely within its rated breaking capacity.

The 3NWTSS63 combines:

• 63 A rated current

• 415 V AC rated voltage

• 80 kA breaking capacity

• GG operating class

• A3 fuse size

• Offset tag construction

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

Suitable for Industrial Electrical Systems

The 3NWTSS63 can be considered for compatible applications such as:

• Electrical distribution panels

• Industrial control panels

• Motor protection circuits

• Feeder circuits

• Power distribution systems

• Industrial machinery

• Commercial electrical installations

• Replacement of compatible BS-type HRC fuses

Actual use should be based on the fuse rating, system fault level and coordination requirements of the installation.

Fuse Replacement Applications

The 3NWTSS63 can be used as a replacement where an existing fuse requires the same:

• Rated current

• Rated voltage

• Breaking capacity

• Size

• Tag configuration

• Operating class

A fuse should never be replaced simply because its current rating appears similar. The physical and electrical specifications of the original fuse should be checked before replacement.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 3NWTSS63 is relevant for:

• Electrical panel builders

• Industrial buyers

• Maintenance departments

• Electrical contractors

• OEM equipment manufacturers

• 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.
