Surface-mounted enclosure with space for 6-circuit controller SZNS-2 — dimensions 50×765×148 mm, model SZNS-2

Surface-mounted enclosure SZNS-2 is a slim, wall-mounted housing designed to accommodate a controller for up to six circuits. With external dimensions of 50 × 765 × 148 mm, this enclosure provides a compact, protected space for electrical or automation control components in residential and commercial installations. The design prioritizes easy mounting on vertical surfaces while keeping internal devices accessible for maintenance and wiring.

Advantages

The enclosure offers a space-efficient footprint that minimizes wall intrusion while still providing sufficient depth for controller modules and terminal connections. Its surface-mounted format simplifies installation where in-wall mounting is impractical. Constructed to separate control equipment from direct exposure, the housing supports organized wiring and reduces the risk of accidental contact. The uniform rectangular shape and consistent internal volume facilitate orderly component placement and heat distribution.

Suitable for

• Installation of controllers for up to six independent circuits
• Electrical distribution and junction points in residential buildings
• Automation equipment mounting in small commercial sites
• Heating and cooling controller housing for zone control systems

Key specifications

• Mounting type: surface/wall-mounted
• Capacity: space for a controller supporting up to six circuits

How to use

Mount the enclosure on a suitably rated wall using fasteners that match the wall material and expected load. Before installing live equipment, ensure the enclosure is fixed level and at an accessible height. Install the controller and any terminal blocks or DIN-rail accessories inside the enclosure following the controller manufacturer's mounting instructions. Route wiring through designated knockouts or cable entries, secure cables with glands or clamps where required, and maintain clearance for ventilation and service access.

Usage recommendations

Use the enclosure indoors in environments that conform to the environmental ratings of the installed controller and associated components. Confirm compatibility of mounting accessories and cable entries with the controllers and wiring you plan to use. For installations involving mains voltage or complex control wiring, engage a qualified electrician or authorized installer to ensure compliance with local regulations and safe operation.
