Product Description

Siemens 3NH3030-0RC DIN Fuse Base – 160A, Size 00, for 3NA HRC Fuse Links

The Siemens 3NH3030-0RC is a SENTRON low-voltage HRC fuse base designed for compatible Siemens 3NA DIN HRC fuse links. The corresponding Siemens 3NH3030 configuration is a 1-pole, 160 A, Size 00 (NH00) fuse base with a flat terminal, M8 connection screw, and compatibility with conductors up to 95 mm² under the specified terminal arrangement. Siemens currently lists the corresponding 3NH3030 as cancelled since June 30, 2025, with 3NH6030 ceramic/steel and 3NH1030 plastic identified as successors.

For SB Smart, this product is best positioned as a Siemens industrial electrical protection accessory for fuse mounting, panel assembly, maintenance, replacement and procurement requirements.

Siemens 3NH3030-0RC DIN Fuse Base

The 3NH3030-0RC belongs to the Siemens 3NH low-voltage HRC fuse-base range used with compatible Siemens 3NA fuse links. Siemens' current documentation identifies the corresponding 3NH3030 as a Size 00, 1-pole, 160 A, 690 V LV HRC fuse base with a flat-terminal connection.

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 3NH3030 configuration is rated at 160 A. Siemens technical data confirms the 160 A rating.

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

Size 00 / NH00 Fuse System

The 3NH3030-0RC is a Size 00 fuse base, corresponding to the NH00 fuse-system size according to EN 60269-1. Siemens' technical data explicitly identifies the fuse-system size as NH00.

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

Designed for Siemens 3NA HRC Fuse System

The 3NH3030-0RC is part of the Siemens 3NA/3NH low-voltage HRC fuse system. Siemens' fuse-system documentation lists 3NH3030 under the 000/00 fuse-base group.

The exact 3NA fuse article should be checked before installation to ensure that its current rating, voltage, utilization category and physical configuration are compatible.

1-Pole Construction

The 3NH3030 is a 1-pole fuse base. Siemens' official technical data specifies one pole for the exact configuration.

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

Flat Terminal Connection

The exact 3NH3030 uses a flat-type terminal. Siemens specifies an M8 connection screw for both the nut and connection screw in this configuration.

The corresponding product description identifies the flat-terminal arrangement as suitable for up to 95 mm² under the specified connection configuration.

The terminal arrangement should be considered during panel design to ensure suitable busbar or conductor connections.

690 V AC Rating

Siemens' current product description specifies 690 V for the 3NH3030 and also identifies a 1000 V designation in the product description.

For actual application, the relevant voltage rating of the complete fuse system and selected fuse link should always be verified from the applicable Siemens technical documentation.

Compatible Fuse Protection System

The 3NH3030-0RC is a fuse base, not the fuse link itself. It provides the mounting and electrical connection for a compatible 3NA LV HRC fuse.

The complete protection arrangement should be selected according to:

• Fuse current rating

• System voltage

• Fuse size

• Breaking capacity

• Utilization category

• Holder/base compatibility

Industrial Fuse Protection Applications

The 3NH3030-0RC 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 3NH3030-0RC can be relevant when maintaining existing equipment that uses the Siemens 3NH3030 configuration or when replacing a compatible Size 00 DIN fuse base.

Before replacement, verify:

• Fuse-link type

• NH fuse size

• Rated current

• System voltage

• Terminal configuration

• Mounting arrangement

• Electrical clearances

• Compatibility with the selected fuse

Because Siemens currently marks the corresponding 3NH3030 as cancelled, stock and replacement compatibility should be confirmed before ordering.

Siemens Successor Products

Siemens currently lists the following successors for the cancelled 3NH3030:

• 3NH6030 ceramic/steel

• 3NH1030 plastic

The Siemens Industry Mall states that 3NH3030 was cancelled effective June 30, 2025.

A successor should not be treated as automatically interchangeable without verifying the mechanical installation, terminal arrangement and electrical requirements of the existing application.

Standardized Siemens 3NH Fuse Base Range

Siemens' current fuse-system guide lists the following main LV HRC fuse-base families:

• 3NH3030 / 3NH4030 – Size 000/00

• 3NH3120 – Size 0

• 3NH3230 – Size 1

• 3NH3330 – Size 2

• 3NH3420 / 3NH3430 – Size 3

This provides a standardized path for selecting compatible fuse bases according to fuse size and application requirements.

The above specifications are based primarily on Siemens' current Industry Mall and technical data for 3NH3030.

Why Choose Siemens 3NH3030-0RC?

The Siemens 3NH3030-0RC corresponds to the 3NH3030, a 160 A, Size 00, 1-pole DIN LV HRC fuse base with a flat-terminal/M8 connection for compatible Siemens 3NA fuse systems.

However, Siemens currently lists the corresponding 3NH3030 as cancelled since June 30, 2025, with 3NH6030 ceramic/steel and 3NH1030 plastic shown as successors. Customers should therefore confirm availability and compatibility before purchasing this legacy article.
