Product Description

Siemens 3NH3032-0RC DIN Fuse Base – 160A, Size 00/000, Saddle-Type Terminal

The Siemens 3NH3032-0RC is a SENTRON low-voltage HRC fuse base for the Siemens 3NA DIN fuse system. The exact article is a 1-pole, 160 A, Size 00/000 fuse base with a saddle-type terminal. Siemens technical documentation specifies 690 V AC and 440 V DC ratings for the corresponding 3NH3032 fuse base. Siemens currently marks the corresponding 3NH3032 product as discontinued since June 24, 2025, with 3NH1032 plastic listed as the successor.

For SB Smart, this product should therefore be presented as a Siemens industrial electrical protection accessory for replacement, maintenance and procurement, with product availability confirmed before ordering.

Siemens 3NH3032-0RC DIN Fuse Base

The 3NH3032-0RC belongs to the Siemens 3NH LV HRC fuse-base family, used with compatible Siemens 3NA fuse links. Siemens documentation identifies the corresponding 3NH3032 as a Size 00/000, 1-pole, 160 A fuse base with a saddle-type terminal.

The fuse base provides the mechanical mounting and electrical connection for the compatible fuse link. The actual overcurrent protection is provided by the HRC fuse installed in the base.

160 A Rated Current

The exact 3NH3032 configuration is rated at 160 A. Siemens' technical data confirms the 160 A operating current rating.

The 160 A rating should be considered together with the selected fuse link, conductor capacity, system voltage and the complete protection-coordination requirements.

Size 00/000 Fuse System

The 3NH3032-0RC belongs to the Size 00/000 Siemens DIN fuse-base category. Siemens' configuration manual lists the 3NH3032 in the 000/00, 1-pole, 160 A fuse-base group.

The physical dimensions of the fuse link must correspond to the fuse base. For replacement applications, the existing fuse size should therefore be checked before ordering.

Designed for Siemens 3NA HRC Fuse System

The 3NH3032-0RC is part of the Siemens 3NA/3NH LV HRC fuse system.

Compatible fuse selection must take into account:

• Fuse size

• Rated current

• Rated voltage

• Utilization category

• Breaking capacity

• Physical configuration

The exact 3NA fuse article should be verified before installation.

1-Pole Construction

The 3NH3032 is a 1-pole fuse base. Siemens technical documentation specifies one pole for this configuration.

This arrangement is suitable where individual fuse mounting is required in a low-voltage HRC protection assembly.

Saddle-Type Terminal

The exact 3NH3032 uses a saddle-type terminal. Siemens' configuration manual identifies the terminal arrangement as a saddle-type terminal, while the technical data specifies a 6 to 70 mm² conductor range for this connection.

This connection arrangement is useful for compatible industrial electrical installations where the specified conductor cross-section and terminal configuration are required.

690 V AC Rating

Siemens technical data specifies a 690 V AC supply-voltage rating for the corresponding 3NH3032 fuse base.

The system voltage should always be verified against both the fuse base and the selected HRC fuse link.

440 V DC Rating

The corresponding Siemens technical data also specifies 440 V DC for the 3NH3032 fuse base.

DC application should be considered only when the selected fuse link and complete protection system are also rated for the intended DC conditions.

120 kA AC Short-Circuit Strength

The Siemens 3NH LV HRC fuse-base system specifies up to 120 kA AC short-circuit strength, with 25 kA DC under the documented conditions.

The complete protection assembly must still be selected according to the prospective fault current and protection-coordination requirements of the actual installation.

DIN-Type Fuse Base

The 3NH3032-0RC is a DIN-type fuse base intended for the Siemens LV HRC fuse system.

The fuse base itself does not provide the complete circuit-protection function. It provides the mounting and electrical connection interface for the appropriate HRC fuse link.

Fixed Fuse-Base Installation

The 3NH3032 family is a fixed LV HRC fuse-base configuration. Siemens' technical documentation describes the 3NH range as fixed fuse bases and also provides separate variants for other connection arrangements.

The mounting arrangement should be checked against the existing panel before replacement.

Industrial Fuse Protection Applications

The 3NH3032-0RC can be considered for compatible applications such as:

• Industrial distribution panels

• Low-voltage feeder protection

• Electrical switchboards

• Power distribution assemblies

• Industrial equipment protection

• DIN HRC fuse installations

• Fuse-base replacement

• Electrical maintenance applications

Actual application should be based on the complete electrical protection design.

Fuse Base Replacement and Maintenance

The 3NH3032-0RC can be relevant when an existing Size 00/000 DIN fuse base requires replacement or when maintaining equipment that already uses this Siemens fuse-base configuration.

Before replacement, verify:

• Fuse-link type

• Fuse size

• Rated current

• System voltage

• Terminal configuration

• Mounting arrangement

• Electrical clearances

• Compatibility with the selected fuse

Because Siemens now identifies the corresponding 3NH3032 as discontinued, customers should also confirm whether the original article is available or whether the Siemens-listed successor is appropriate for their installation.

Siemens Successor Product

Siemens currently states that the 3NH3032 is no longer available and identifies 3NH1032 plastic as its successor.

This is important for replacement procurement. The successor should not be treated as automatically interchangeable without checking the electrical, mechanical and installation requirements of the existing assembly.

Standardized Siemens 3NH Fuse Base Range

Siemens documentation provides several LV HRC fuse-base configurations across different fuse sizes and current ratings. The 3NH3032 is part of the 000/00, 160 A category, alongside other terminal variants such as the 3NH3030 and 3NH3031.

This allows different terminal arrangements to be selected according to panel and conductor requirements.

The technical values above are based primarily on Siemens documentation for the corresponding 3NH3032 configuration.
