Overview

The Vimar VMV55106 is an IP55-rated surface-mount junction box sized 150 x 110 x 70 mm for protecting electrical splices and terminations in damp, splash-prone areas on a boat.

The enclosure is plastic with a grey RAL 7035 finish, and the cover closes with stainless steel screws. Cable entries use trimmable step membranes and suit 20 mm or 25 mm conduit, which helps keep runs neat and reduces cable movement where vibration is constant.

This box makes sense for deck and cockpit accessories, console wiring, and locker or lazarette circuits where you want connections enclosed and protected, but you are not installing in a space that can flood or remain submerged.

Key features

• IP55-rated enclosure for protection against dust and water spray
• 150 x 110 x 70 mm surface-mount box for bulkhead or overhead installation
• Up to 10 cable entry points with trimmable step membranes
• Entry system sized for 20 mm and 25 mm conduit
• Cover secured with stainless steel screws to hold tight in vibration-prone installs
• Rated insulation voltage (Ui): 450 V
• Working temperature range: 0 C to 60 C
• Grey RAL 7035 finish for a clean, low-contrast look in equipment spaces

Compatibility and fit

The rectangular body is intended for surface mounting, so it works well when you do not have the depth for a recessed box. Plan space around the lid so it can be removed for inspection and future service, especially if the box is mounted under a hardtop or inside a console.

The conduit-friendly entries are useful when you are protecting cable runs through lockers, under gunwales, or along a bulkhead where chafe protection matters.

Installation and setup

Mount the box on a flat surface and route cables so they approach from below or from the side when possible. Leave enough slack to open the cover without pulling on splices, and secure the cable run nearby so the entry points are not taking the full load of vibration.

Trim only the membrane steps you need for the cable or conduit size being used. Keep outer jackets intact into the box so water does not track along conductors, and keep unused entries sealed.

Electrical and system integration

This is a protective enclosure, not a terminal block by itself, so connection quality depends on the splices and terminations you install inside. Use tinned marine conductors and sealed connectors suited to your circuit, and keep connections positioned so the lid can close without pinching insulation.

Maintenance and checks

After the first few outings, check that the cover screws are snug and that the entry membranes still grip the cable or conduit cleanly. Any time the box is opened, wipe the sealing surfaces before closing it again so the IP55 protection is not compromised by grit or salt residue.
