Why Choose the ABB ZH440 NH1 Triple Shutter Closed?
The ABB ZH440 NH1 Triple Shutter Closed (2CPX062963R9999) is a purpose-specified NH1 triple-shutter component designed for integration into compatible ABB electrical sub-distribution assemblies. Belonging to ABB's DESUJ Sub Distribution product group, the ZH440 provides a dedicated closed-shutter arrangement for electrical distribution equipment associated with the NH1 fuse system.
Designed for professional low-voltage electrical distribution applications, the ZH440 features a triple-shutter configuration intended for compatible NH1 equipment arrangements. Shutter components are used within electrical assemblies to cover designated openings or equipment interfaces according to the manufacturer's design. The ZH440's closed configuration makes it a specifically identified component for installations requiring this particular shutter arrangement rather than a generic NH1 accessory.
Identified by ABB order code 2CPX062963R9999, the ZH440 supports accurate component selection for electrical contractors, switchboard manufacturers and maintenance professionals. Its NH1 equipment designation, triple-shutter arrangement and closed configuration are important selection characteristics. Exact mechanical compatibility, mounting requirements and protective performance must be verified against the relevant ABB technical documentation before installation.

Understanding NH1 Triple-Shutter Configurations in Electrical Distribution
NH1 is a recognised size designation within the NH low-voltage fuse system, which is commonly used in electrical distribution installations incorporating suitably rated fuse-links and associated equipment. Electrical distribution assemblies may require specific shutter components to complete their mechanical arrangement or cover designated equipment interfaces. The correct shutter configuration depends on the manufacturer's assembly design, mounting arrangement and associated NH equipment. An NH1 designation alone does not establish interchangeability between different shutter components, fuse disconnectors or enclosure systems.
The ABB ZH440 is identified specifically as an NH1 Triple Shutter Closed component. The triple designation distinguishes it from double-shutter arrangements, while the closed designation identifies its specified configuration. These descriptions do not independently establish the component's physical dimensions, operating mechanism, number of poles, degree of contact protection or enclosure ingress protection rating. The ZH440 is a mechanical shutter component rather than an NH fuse-link or an electrical protection device. Its exact installation position, compatible equipment and contribution to the completed assembly's protective construction should be confirmed using ABB's technical documentation.
