## Long description

SiGMA-Li SZN-4 is a surface-mounted overdoor enclosure designed to house and organize electrical and communication modules in a compact footprint above doorways. The cabinet contains ten separate sections that allow installers to place circuit breakers, terminal blocks or small patch panels in a neat, accessible arrangement. Built for wall-mounted distribution in residential or light-commercial settings, the enclosure supports straightforward cable routing and helps maintain tidy service access without requiring recessing into the wall.
Advantages
The SiGMA-Li SZN-4 offers segmented compartments that simplify installation and future service by isolating circuits and connectors. Its surface-mounted design eliminates the need for wall recessing, enabling faster installation and flexible placement directly above doors. The enclosure's compact dimensions and ten-section layout provide a balance between capacity and space efficiency, helping to reduce clutter and improve cable management in confined spaces.
Suitable for
Residential electrical distribution and sub-panels
Light-commercial installations with limited wall depth
Mounting small circuit breakers, terminal blocks or patch panels above doorways
Neat cable routing and localized connection points for telecommunication or alarm systems
Key specifications
Surface-mounted overdoor enclosure with ten internal sections for module separation
Wall-mounted installation intended for placement above door openings
Compartments sized to accept small breakers, terminal blocks and compact patch panels
Designed for residential and light-commercial distribution use
How to use
Position the enclosure above the door at a height that provides safe and convenient access, ensuring the mounting surface is level and capable of supporting the cabinet weight and installed components. Fix the unit to the wall using appropriate anchors and screws for the substrate, then route incoming and outgoing cables into the enclosure through designated entry points. Install breakers, terminal blocks or patch panels into the segmented sections according to the electrical plan, and secure wiring following local electrical standards and safety regulations.
Usage recommendations
Verify compatibility of the chosen breakers and modules with the physical dimensions of the enclosure sections before installation and observe local electrical codes. For installations where higher IP protection or larger capacity is required, consider an alternative enclosure designed for recessed or larger-panel mounting.
