Junction box SEZ 18-way surface-mounted 135×90×40 mm IP54 gray

SEZ 18-way surface-mounted junction box, 135×90×40 mm, IP54 in gray is a compact ABS enclosure intended for electrical wire terminations and branch connections in indoor and sheltered outdoor applications. The rectangular housing provides 18 connection ways in a shallow footprint, enabling neat distribution and secure protection of junctions where resistance to dust and splashing water is required. Its surface-mounted design allows installation on walls, panels or other flat surfaces without embedding into structures.

Advantages

The enclosure is made of impact-resistant ABS material that combines mechanical strength with a lightweight construction. Its IP54 protection rating shields internal connections from dust ingress and water splashes, extending service life in non-submerged environments. The compact dimensions (135×90×40 mm) save installation space while providing adequate room for wiring and terminals. The gray finish gives a neutral appearance suitable for residential, commercial or light industrial settings.

Suitable for

• Electrical wire terminations and splicing in indoor installations
• Small distribution or branch points for lighting and power circuits
• Mounting on walls, cabinets or panels where surface-mounted enclosures are preferred
• Environments requiring protection against dust and water splashes (IP54)

How to use

Position the junction box on the selected surface and mark fixing points according to the enclosure’s base. Secure the box using appropriate screws or anchors for the mounting substrate. Open the enclosure, route cables through the entry points or pre-cut knockouts, and secure conductors to suitable terminals or connectors inside. Ensure cable entries are sealed where necessary to maintain IP54 protection, then close and fasten the cover. Verify that all connections are tightened and insulated before restoring power.

Usage recommendations

Use the junction box in dry or sheltered outdoor locations where exposure is limited to dust and splashes; avoid installation in continuously wet or submerged conditions. Choose sealing grommets or silicone sealant at cable entries when additional protection is needed. Observe local electrical standards and de-energize circuits before working on wiring.
