Wall-mounted electrical enclosure SiGMA-Li SZN-5 — 12 sections, overboard cabinet

SiGMA-Li SZN-5 is a wall-mounted electrical enclosure with 12 sections designed to accommodate circuit breakers and related distribution components. The overboard cabinet layout provides separated compartments for organized wiring and clear segregation of modules, suitable for surface mounting where recessed installation is not possible. The enclosure is intended for use in residential and small commercial electrical distribution installations and supports tidy arrangement of protective devices and wiring routes.

Advantages

The overboard cabinet design simplifies installation on finished walls by avoiding wall recessing. Twelve sections allow flexible allocation of circuit breakers and distribution modules while maintaining physical separation between circuits. The enclosure supports orderly cable management and reduces congestion inside the panel, improving accessibility for maintenance. Constructed for safe mounting and clear layout, it helps comply with common installation practices for small distribution boards.

Suitable for

• Residential electrical distribution boards
• Small commercial or retail electrical panels
• Surface-mounted installations where wall recessing is not available
• Organized grouping of circuit breakers and modular protective devices

Key specifications

• Wall-mounted overboard cabinet configuration with external mounting flange
• 12 separate sections for installation of circuit breakers and modular components
• Compartmentalized internal layout to facilitate neat wiring and separation of circuits
• Designed for surface mounting on finished walls
• Accessible front for installation and maintenance of distribution modules

How to use

Mount the enclosure on a structurally suitable wall using appropriate anchors and fasteners for the wall material, ensuring it is level and securely fixed. Install DIN-rail mounted circuit breakers and modular devices within the 12 available sections following applicable wiring rules and maintain clearances for safe operation. Route incoming and outgoing conductors through the provided entry points or knockouts, secure wiring with clamps or ties as required, and ensure proper grounding of the enclosure and installed equipment. Verify all connections and protective device settings before energizing the panel.

Usage recommendations

Use certified modular circuit breakers and accessories compatible with the enclosure’s mounting system, and follow local electrical codes for protection, spacing, and earthing. Leave adequate space around the cabinet for ventilation and future maintenance; schedule periodic inspections to confirm tight connections and intact insulation.
