Overview

The Vimar VMV55207 is an IP56-rated surface-mount junction box used to protect electrical connections in areas that see spray, washdowns, and general moisture on board. The enclosure measures 190 x 140 x 70 mm and comes in RAL 7035 grey, with a plastic body and a blind cover that fastens down with stainless steel screws.

It is rated with an insulation voltage (Ui) of 450 V and is specified for use from 0 C to 60 C. The walls are undrilled, so cable entries can be placed where they make sense for your run and finished with the right glands or conduit fittings to keep the seal intact.

Key features

• IP56 protection for spray and washdowns in exposed areas
• Surface-mount format for bulkheads, lockers, and panels
• Undrilled walls so cable entries can be placed where your wiring actually routes
• Blind cover secured with stainless steel screws
• Overall size: 190 x 140 x 70 mm
• Rated insulation voltage (Ui): 450 V
• Specified working temperature: 0 C to 60 C
• RAL 7035 grey finish for a neutral, low-visibility install

Installation and setup

Mount the box to a flat surface where the cover screws remain accessible for future inspections. Plan entry points before drilling, then use appropriate cable glands or conduit fittings sized for your cable and jacket so the seal is not compromised. Leave enough slack inside for service, keep splices or terminal blocks supported, and tighten the cover screws evenly so the gasket seats consistently.

Compatibility and fit

This is a protective enclosure, so the electrical limits of your installation depend on the terminals, connectors, and cable you install inside it. The 450 V insulation rating suits many common on-board circuits, but it does not replace correct fuse or breaker sizing, proper strain relief, or good separation between DC and AC wiring where required. Confirm the footprint fits your mounting area and that you can route cables without sharp bends at the entry points.

Use on board

This box is a good match when you are cleaning up exposed junctions on deck, in cockpit lockers, under hardtops, or around masts and radar supports where wiring needs protection from spray. It also works well during refits where cable routing is not standardized and you want the freedom to place entries exactly where the run dictates.

Maintenance and checks

After the first few outings, recheck gland tightness and confirm the cover gasket is seated properly. In saltwater use, a quick rinse and periodic inspection for grit around the seal helps maintain the IP rating over time.
