Product Description

Siemens 3NH34304RC DIN Fuse Base – 800A, Size 3, for 3NA33 Fuse Links

The Siemens 3NH34304RC is a DIN-type fuse base from the Siemens 3NH series, designed for use with compatible 3NA33 HRC fuse links. The exact article is rated at 800 A and belongs to Size 3. Siemens' published product documentation lists 3NH3430-4RC as the 800 A DIN fuse base suitable for 3NA33 fuse links.

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

Siemens 3NH34304RC DIN Fuse Base

The 3NH34304RC belongs to the Siemens 3NH DIN fuse-base range used with Siemens 3NA HRC fuse links. Siemens documentation lists different fuse bases according to fuse size and current rating, with the 3NH3430-4RC specifically intended for the 800 A / Size 3 application.

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

800 A Rated Current

The exact 3NH34304RC has a rated current of 800 A. Current Siemens-related product information identifies the article as an 800 A DIN fuse base.

The base rating must be considered together with the selected fuse link, conductor capacity, system voltage and complete protection design.

Size 3 Fuse Base

The 3NH34304RC is a Size 3 DIN fuse base. Siemens' product range places this 800 A version under Size 3.

Physical fuse size is an important selection parameter because the fuse link must mechanically fit the base.

Suitable for 3NA33 Fuse Links

The 3NH34304RC is specified for 3NA33 fuse links. Siemens documentation lists the 800 A base as 3NH3430-4RC, suitable for fuse-link type 3NA3 3.

This compatibility should be verified before ordering to ensure that the selected HRC fuse link matches the required physical and electrical configuration.

DIN-Type Fuse Base

The 3NH34304RC is a DIN-type fuse base intended for the Siemens 3NA HRC fuse system.

The fuse base does not replace the fuse link. Instead, it provides the installation interface for the compatible DIN-type HRC fuse.

LV HRC Fuse System

The Siemens 3NA range is designed for low-voltage HRC fuse protection, while the 3NH series provides the corresponding fuse bases and accessories. Siemens documentation lists the 3NA range with high breaking capacity and the 3NH fuse bases according to DIN fuse sizes.

The complete assembly should be selected according to the system voltage, current, fault level and protection-coordination requirements.

Industrial Fuse Protection Applications

The 3NH34304RC can be considered for compatible applications such as:

• Industrial distribution panels

• High-current feeder protection

• Power distribution assemblies

• Electrical switchboards

• Industrial machinery protection

• Main power-distribution circuits

• Fuse replacement installations

• Electrical maintenance applications

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

Fuse Replacement and Maintenance

The 3NH34304RC is useful when an existing DIN fuse base needs replacement or when a new industrial panel requires a mounting base for a compatible 3NA33 HRC fuse link.

Before replacement, verify:

• Fuse-link type

• Rated current

• Fuse size

• System voltage

• Mounting arrangement

• Terminal configuration

• Electrical clearances

• Compatibility with the selected HRC fuse
