Overview

The Vimar VMV55001 is an IP44-rated surface-mount junction box for protecting wiring connections where you need splash protection and quick access for service.

It has a round body with a 65 mm diameter and 35 mm depth, which helps when you are fitting it behind panels or inside lockers where space is tight. The cover is a blind, snap-closed style, so you can open it for inspection without tools in most installations.

Four trimmable step membrane inlets support conduit/tube diameters of 20 mm or 25 mm. Rated insulation voltage (Ui) is 450 V, and the specified operating temperature range is 0°C to 60°C.

Key features

• IP44 protection level for locations exposed to dust and splashing water
• Compact footprint with a 65 mm diameter and 35 mm depth for confined mounting areas
• Surface mounting on walls or ceilings for straightforward retrofits and clean routing
• Snap-closed blind cover for fast access during troubleshooting and re-termination
• Four trimmable step membrane inlets to suit cable and conduit entry needs
• Supports 20 mm and 25 mm tube diameters for common marine conduit runs
• RAL 7035 grey finish for a neutral look inside technical spaces

Installation and setup

Mount the box on a flat surface where the cover can open fully and where the inlets can be oriented to keep water from pooling around cable entries. Trim each step membrane gradually so the cable or conduit passes through snugly, then keep bends gentle to avoid stressing terminations inside the box.

Because this is a junction box, plan enough slack to re-terminate in the future and leave room for connectors or terminal blocks you may be using inside. After wiring, confirm the cover is fully snapped closed around the entire perimeter.

Compatibility and fit

This box is meant for surface mounting and routing smaller accessory wiring runs or control wiring where a protected splice point is needed. Conduit/tube sizing is 20 mm or 25 mm, and the four entry points make it easier to bring in a feed and branch circuits without overcrowding a single side.

With an IP44 rating, it suits areas that see spray or condensation but are not subject to direct, sustained water exposure. For locations that can flood or take pressurized washdowns, use a higher protection level enclosure instead.

Use cases on board

Common installs include behind a helm panel, inside a console, in a cockpit locker that stays mostly dry, or on an interior bulkhead where wiring transitions from a trunk line into smaller branches.

This is a good match for boat owners and installers who want a small junction point with splash protection and a clean surface-mount layout. It also fits refits where you are adding new accessories and need a tidy place to manage splices without opening up larger panels.
