Cabinet Type SiGMA-Li SZN-3 8-section surface-mounted 585×145×585 mm

SiGMA-Li SZN-3 is a surface-mounted electrical cabinet with 8 sections and compact external dimensions of 585×145×585 mm. Designed for mounting on walls, this enclosure accommodates standard DIN modular devices, distribution blocks and wiring, providing an organized grouping of circuits for residential or light-commercial electrical installations. The cabinet allows straightforward access for maintenance and offers provisions for cable entry and internal arrangement of components.

Advantages

The cabinet’s surface-mounted design enables installation without recessing into walls, reducing installation time and structural alterations. With eight sections and standard DIN compatibility, it supports a wide range of modular devices to create tailored circuit distribution. Its compact footprint balances space efficiency with capacity for multiple components, while providing clear internal segregation of circuits to simplify wiring and troubleshooting.

Suitable for

• Residential electrical distribution and circuit grouping
• Light-commercial installations such as small shops or offices
• Wall-mounted distribution for renovation projects where flush mounting is impractical
• Housing of DIN-rail mounted breakers, switches and terminal blocks

Key specifications

• Mounting type: surface-mounted, wall installation
• Number of sections: 8
• External dimensions (W×D×H): 585 × 145 × 585 mm
• Compatibility: supports standard DIN modular components and DIN-rail mounting
• Material and finish: durable enclosure suitable for indoor electrical environments
• Access: front access for maintenance and wiring

How to use

Mount the cabinet on a suitable vertical surface using appropriate fasteners for the wall material and ensuring the enclosure is level. Install DIN-rail mounted devices and distribution blocks inside the sections according to the planned scheme, maintaining required clearances and following national electrical regulations. Route incoming and outgoing cables through designated entry points, secure conductors to terminal blocks or devices, and verify connections before restoring power. Ensure the cover is properly closed and secured after installation.

Usage recommendations

Plan the internal layout in advance to allow space for future expansions and to keep load circuits separated. Use labeled terminal blocks and cable markers to simplify maintenance. Always follow local electrical standards and have final wiring verified by a qualified electrician.
