Electrical enclosure SATEL OPU-1A, dimensions 158×32×126 mm

SATEL OPU-1A is a compact surface-mounted electrical enclosure made of white ABS plastic, sized 158×32×126 mm. It is designed to house small electronic modules, connection assemblies, wiring and small PCBs in low-voltage installations. The enclosure features a neutral aesthetic suitable for visible interior locations and includes a tamper switch for basic intrusion detection of the enclosure cover.

Advantages

The enclosure combines a compact footprint with a durable ABS construction that resists everyday mechanical stress and provides electrical insulation. Its neutral white finish and unobtrusive design allow installation in residential and commercial interiors without visual disruption. The integrated tamper switch adds an additional layer of protection by detecting unauthorized opening of the cover. The surface-mount form factor simplifies installation on walls or panels and enables easy access to wiring and mounted modules.

Suitable for

• Housing small alarm and security modules and expanders
• Mounting connection blocks, terminals and small printed circuit boards
• Use in access-control and low-voltage installations in interior spaces
• Surface-mounted installations on walls and panels where visible placement is acceptable

Key specifications

• Material: ABS plastic
• Mounting type: surface-mounted (wall/panel)
• External dimensions (W×D×H): 158×32×126 mm
• Color: white
• Integrated tamper switch for cover monitoring
• Capacity: space for small PCBs, wiring and terminal blocks

How to use

Open the cover to place the electronic module, PCB or connection assemblies inside the enclosure and route wiring through the designated entry points. Secure the module and any terminal blocks using appropriate screws or mounting clips compatible with the enclosure interior. Connect all wiring according to the system documentation, then close the cover and verify that the tamper switch is properly engaged and connected to the security or control system. Install the enclosure on a flat vertical surface or panel using appropriate fixings for the substrate material.

Usage recommendations

Install the enclosure in dry interior environments and avoid exposure to direct sunlight and extreme temperatures. Use cable glands or grommets as needed to protect wiring entries and maintain ingress protection. Verify compatibility of the mounted modules with the enclosure dimensions before installation and ensure the tamper switch is connected to the monitoring circuit where required.
