Surface-Mounted Hermetic Junction Box ELEKTROPLAST PH-1B.1 108 mm gray

Surface-mounted hermetic junction box ELEKTROPLAST PH-1B.1 108 mm gray is a compact, round enclosure designed to protect electrical connections and splices from dust and moisture. The sealed housing suits installations where a tight barrier is required to safeguard cable joints, terminal blocks and small electronic components. Its surface-mounted form allows straightforward placement on walls, panels or other flat surfaces in indoor and sheltered outdoor locations.

Advantages

The enclosure provides a hermetic barrier against moisture and particulate ingress while maintaining easy access for installation and maintenance. Its round 108 mm diameter profile optimizes internal space for typical cable junctions without excess bulk. The gray finish offers a neutral appearance that integrates with common electrical fittings and interior surfaces. The construction materials are chosen for electrical insulation and durable performance under normal ambient conditions.

Suitable for

• Protection of cable splices and electrical joints in residential and commercial buildings
• Housing small terminal blocks and connection points for lighting circuits
• Enclosing small electronic modules or sensor connections in sheltered outdoor areas
• Use where a sealed, surface-mounted junction box is required for safety or regulatory compliance

Key specifications

• Shape: round surface-mounted enclosure
• External diameter: 108 mm
• Color: gray
• Mounting type: surface-mounted on flat substrates
• Protection: hermetic/sealed against dust and moisture
• Intended use: cable joints, terminal blocks, small electronic components

How to use

Prepare cable entries and secure the junction box to a flat surface using appropriate screws or anchors for the substrate. Make cable terminations and connection points inside the enclosure, ensuring the joint area is arranged to avoid strain on conductors. After completing connections, close and seal the lid according to the manufacturer's fitment to restore the hermetic barrier. Verify that any cable glands or entry points are properly sealed to maintain protection against moisture and dust.

Usage recommendations

Use the enclosure in dry indoor or sheltered outdoor locations; avoid prolonged exposure to direct weathering unless additional sealing measures are applied. Choose fixation hardware suitable for the mounting surface and ensure cable entries are sealed with compatible grommets or glands to retain hermetic performance.
