Overview

The Vimar VMV55206 is a surface-mount junction box for protecting electrical connections in wet, dusty areas on board. It carries an IP56 protection rating and measures 150 x 110 x 70 mm, giving you a clean place to land splices, connectors, or small terminal blocks instead of leaving them loose behind panels.

The housing is plastic in RAL 7035 grey with a blind cover held by stainless steel screws, which helps the lid stay tight when the boat is vibrating underway. It is specified for a working temperature range of 0 to 60 C and a rated insulation voltage of 450 V, which suits many common DC and AC junction enclosure needs when the rest of the installation is matched correctly.

Key features

• IP56 protection rating for spray and washdown-exposed mounting locations
• 150 x 110 x 70 mm rectangular enclosure for surface mounting on walls and ceilings
• Blind cover secured with stainless steel screws for a lid that stays put under vibration
• Plastic housing in RAL 7035 grey for a neutral finish that blends into most installs
• Working temperature range: 0 to 60 C
• Rated insulation voltage: 450 V

Installation and setup

This box is meant for surface mounting, so it is commonly screwed to a bulkhead, inside a console, in a locker, or under a hardtop where you can still reach the cover for inspection. Keep cable routes tidy and leave enough slack to open the lid later without pulling on connections.

Maintain the IP56 protection level by sealing every cable entry and avoiding unused openings. Route cables with a drip loop when possible and position entries so water does not track directly into the enclosure.

Compatibility and fit

Before ordering, confirm the available mounting footprint and clearance for the lid and wiring. The 70 mm depth helps when you need room for connectors and bend radius, but tight helm spaces may still require a quick mockup with your wiring bundle.

This junction box is intended for above-water locations where it will see spray, rain, or washdowns. It is not a choice for installations that sit submerged.

Use cases on board

This style of enclosure is commonly used for joining cockpit and deck circuits, organizing wiring transitions under a hardtop, or protecting splices feeding deck lights, pumps, or equipment mounted in lockers. It is a good match for refits where you want serviceable junction points instead of hidden inline splices.

Maintenance and care

Check the lid screws periodically and re-seat the cover after any wiring changes. In saltwater environments, rinse exterior salt buildup during routine washdowns and re-check cable entry sealing if you notice moisture or corrosion near connections.
