Why Choose the ABB ZH441 NH2 400A Fuse Disconnector?
The ABB ZH441 (2CPX062964R9999) is a 400 A NH2 fuse disconnector designed for use in compatible low-voltage electrical distribution assemblies. As part of ABB's DESUJ Sub Distribution product group, this component provides a dedicated solution for integrating NH size 2 fuse-disconnection equipment into electrical distribution systems used in commercial and industrial installations.
The ABB ZH441 combines the functionality of an NH fuse disconnector with a rated current designation of 400 A, supporting the isolation and protection arrangements of compatible low-voltage distribution circuits. NH fuse disconnectors are commonly used in power distribution equipment where replaceable fuse-links provide overcurrent protection and the disconnector arrangement enables controlled circuit disconnection.
With its NH2 size classification and 400 A current rating, the ABB ZH441 is intended for distribution applications requiring a correctly matched fuse-disconnection component. Its manufacturer order code 2CPX062964R9999 enables accurate identification for electrical panel builders, contractors and maintenance engineers selecting equipment for compatible ABB sub-distribution assemblies.

Reliable Fuse Disconnection for Low-Voltage Power Distribution
NH fuse disconnectors are important components in low-voltage power distribution systems, combining a circuit disconnection arrangement with the ability to accommodate appropriately rated NH fuse-links. When correctly specified and installed, the fuse-links provide protection against overcurrent conditions, while the disconnector arrangement supports electrical isolation and maintenance procedures within its approved operating limits.
The ABB ZH441 NH2 400 A Fuse Disconnector is identified for applications requiring an NH size 2 disconnector with a 400 A current rating. Correct selection requires consideration of the complete electrical assembly, including operating voltage, compatible fuse-links, prospective short-circuit current, thermal performance and the manufacturer's installation requirements. The disconnector's current rating should not be confused with the protective characteristics of the fuse-links installed within the system.
Typical Applications
- Low-voltage electrical sub-distribution assemblies.
- Commercial building electrical distribution systems.
- Industrial power distribution panels and switchgear.
- Fuse-protected electrical feeder circuits.
- Electrical distribution boards requiring NH2 fuse-disconnection equipment.
- Manufacturing facilities and industrial infrastructure.
- Electrical panel-building and switchgear assembly projects.
