Marinco bipolar/tripolar plug 4 wires 50 A – code: 14.587.01 – Osculati

Marinco bipolar/tripolar plug 4 wires 50 A (Osculati 14.587.01)

The Marinco 4-wire plug Osculati code 14.587.01 is a component for electrical connections in nautical and onboard systems, designed to create a practical and tidy connection between cable and dedicated socket. The construction is oriented for use in environments where humidity and splashes may be present: the plug is in fact indicated as completely waterproof and with protection rating IP56.

It is a solution suitable for those who want to maintain consistency with the Marinco series and Osculati spare parts, choosing an item identifiable with a unique code and clear description. The plug is to be paired with socket 14.487.01 and is supplied with female contacts.

Features and construction details

Configuration and coupling

• Type: Marinco plug bipolar/tripolar to 4 wires.
• Coupling: to be paired with socket 14.487.01.
• Contact: female contacts (as described).
• Poles: 3 + earth.

Sealing and protection

The plug is indicated as completely waterproof and with IP56. This makes it suitable for installations where it is important to protect the connection from unwanted ingress of water and dust, typical of many applications on deck, in the cockpit or in exposed technical areas.

Materials

• Body: made of high-strength glass-filled thermopolymer.
• Contact: in nickel-plated brass.

The combination of reinforced thermopolymer and nickel-plated brass contacts is a typical choice for components intended for practical and continuous use, where mechanical robustness and contact stability over time are sought.

Electrical data

• Rated current: 50 A.
• Voltage: 125/250 V.

Typical applications

This plug is designed to be used in contexts where Marinco/Osculati connections are used and where a reliable and protected connection is required. In particular, it is suitable for:

• Onboard systems on pleasure and work boats, in the presence of humidity and splashes.
• Mooring maintenance and refitting: replacement of a worn plug while maintaining compatibility with the socket 14.487.01.
• Technical setups where a plug with a robust body and contacts made of material suitable for practical use is preferred.

The configuration 4 wires and the wording bipolar/tripolar makes it suitable for various wiring schemes provided by the series, as long as they are consistent with the indicated mating socket.

Advantages for installers and boat owners

Targeted choice thanks to the Osculati code

The reference 14.587.01 allows immediate identification of the spare part, useful both when ordering and during scheduled maintenance. In the nautical field, where work is often done on existing systems, being able to replicate the original configuration reduces uncertainties and verification times.

Protected connection

The presence of protection for and IP56 is an important element for those installing in environments that are not perfectly dry. A protected connection helps keep the connection tidier and suitable for typical onboard conditions.

Materials oriented for use in technical environments

The glass-filled thermopolymer offers a solid body suitable for frequent handling, while the nickel-plated brass contacts are a common choice to ensure stable electrical contact and good resistance to use.

Usage and operational notes

Mating verification

Before purchase and installation, verify that the system uses the socket 14.487.01, since this plug is indicated as to be mated to that model. In case of replacement, it is advisable to also compare the type of contacts (here female) and the configuration 3 + earth.

Installation and wiring

Wiring must be carried out by qualified personnel, respecting good installation practices and the instructions of the system manufacturer. During assembly, it is good practice to:

• check the integrity of the body and contacts before assembly;
• ensure that the mating with the socket is correct and complete;
• maintain order in cable routing and connection areas, especially in technical compartments.

Maintenance

In a nautical context, periodic verification of connections is useful to identify any signs of wear or need for cleaning. In case of replacement, using an identified spare part (Osculati 14.587.01) helps to maintain consistency with the existing installation.
