Product Description

Siemens 3NP1153-1DA10 SENTRON Fuse Switch Disconnector – 400A, 3-Pole, NH2

The Siemens 3NP1153-1DA10 is a SENTRON 3NP1 fuse switch disconnector designed for low-voltage power distribution and circuit protection applications. The exact article is a 3-pole, 400 A unit for NH1/NH2 fuse links, designed for floor mounting on a mounting plate, with flat terminals, a 70 mm cover level, and without fuse monitoring. Siemens' current datasheet confirms these specifications.

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

Siemens 3NP1153-1DA10 Fuse Switch Disconnector

The 3NP1153-1DA10 belongs to the Siemens SENTRON 3NP1 fuse switch disconnector family, which covers ratings up to 630 A. Siemens' current 3NP1 documentation lists the 400 A version as 3NP1153-1DA10 for NH2/NH1 fuse links.

The device combines switching and fuse-disconnection functions in one compact industrial component. The installed NH fuse links provide the circuit protection, while the 3NP1 device provides controlled isolation and switching of the protected circuit.

400 A Rated Current

The exact 3NP1153-1DA10 is rated at 400 A. Siemens technical data identifies the 3NP1153 family with a rated uninterrupted current of 400 A.

The 400 A rating should be considered together with the selected fuse links, conductor capacity, load characteristics and the complete protection design.

Three-Pole Construction

The 3NP1153-1DA10 has 3 poles. Siemens' official datasheet specifies the exact article as a 3-pole fuse switch disconnector.

The three-pole configuration makes the device suitable for compatible three-phase low-voltage distribution and industrial feeder applications.

NH1 and NH2 Fuse Compatibility

The exact 3NP1153-1DA10 is designed for NH1 and NH2 fuse links. Siemens' current data identifies the compatible fuse-link sizes as NH1 and NH2, while the broader 3NP1 documentation confirms the 400 A 3NP1153 family for NH sizes 2 and 1.

The exact fuse-link rating and type must be selected according to the protected circuit and the manufacturer's requirements.

Without Fuse Monitoring

The product designation specifies without fuse monitoring. Siemens' current datasheet identifies the safety-monitoring design of the exact article as “Without.”

This means the basic version does not include an integrated fuse-monitoring function.

Customers who specifically require electrical fuse-status monitoring should select the appropriate monitored 3NP1 configuration instead.

Floor-Mounted Installation

The 3NP1153-1DA10 is designed for assembly and installation on a mounting plate. Siemens' current product designation explicitly identifies this mounting arrangement.

This makes it suitable for industrial control panels, distribution boards and switchgear assemblies where floor/mounting-plate installation is required.

Flat Terminal Connection

The exact article uses flat terminals. Siemens identifies the 3NP1153-1DA10 with flat-terminal connection technology.

The flat-terminal design supports suitable busbar or conductor connection arrangements when used with the correct hardware and installation method.

70 mm Cover Level

The 3NP1153-1DA10 has a 70 mm cover level. Siemens' current datasheet includes the 70 mm cover-level designation in the product description.

Cover level is an important panel-design parameter because it affects the position of the device relative to the enclosure or protective cover.

690 V Rated Insulation Voltage

Siemens' 3NP1 technical documentation specifies a 690 V rated insulation voltage for the 3NP1 fuse switch disconnector family.

The actual operating voltage and switching category must be checked against the complete installation and the selected fuse links.

LV HRC Fuse System

The 3NP1153-1DA10 uses the Siemens LV HRC fuse system. Siemens' current datasheet identifies the fuse system as LV HRC fuse.

This makes the device suitable for applications where NH-type low-voltage HRC fuse links are used for circuit protection.

Switching and Isolation Function

A fuse switch disconnector provides a means of switching and isolating a protected circuit while incorporating compatible fuse links.

The 3NP1 family is designed for industrial low-voltage power distribution and offers fuse-disconnection functionality in combination with NH fuse protection. Siemens lists the 3NP1 among its SENTRON fuse switch disconnectors up to 630 A.

Mechanical Service Life

Siemens' current datasheet lists a typical mechanical service life of approximately 1,000 operating cycles for the exact product.

The actual service life can depend on operating conditions, switching frequency and installation practices.

Suitable for Industrial Distribution Applications

The 3NP1153-1DA10 can be considered for compatible applications such as:

• Industrial distribution panels

• Main feeder protection

• Power distribution boards

• Motor feeder protection

• Industrial machinery

• Electrical switchboards

• Low-voltage power-distribution systems

• Fuse-based isolation applications

The exact application should be based on system voltage, load current, prospective short-circuit current, fuse selection and protection coordination.

Fuse Replacement and Maintenance

The 3NP1 fuse switch disconnector is useful where NH fuse links need to be installed in a dedicated switching and isolation assembly.

When replacing an existing device, verify:

• Rated current

• Number of poles

• NH fuse size

• Terminal configuration

• Cover level

• Mounting arrangement

• Fuse monitoring requirement

• System voltage

• Protection coordination

Standardized Siemens 3NP1 Range

Siemens' current 3NP1 documentation covers fuse switch disconnectors from 160 A up to 630 A. The corresponding floor-mounted flat-terminal family includes:

• 3NP1133-1CA10 – 160 A

• 3NP1143-1DA10 – 250 A
