Marinco stainless steel tripolar 4-wire socket – code: 14.487.01 – Osculati

Marinco stainless steel tripolar 4-wire Osculati socket (code 14.487.01)

The Marinco stainless steel tripolar 4-wire socket Osculati 14.487.01 it is a component for onboard electrical systems designed for those looking for a solution refined in materials and suitable for exposed environments. The construction is indicated as completely waterproof and combines a body in high-strength glass-filled thermopolymer with nickel-plated brass contacts, for a set designed for use in nautical and plant engineering environments.

This version is described as 4-wire socket with male contacts, made of AISI 316 stainless steel and with protection rating IP56. It is a typical choice when a neat and robust connection point is desired, with attention to protection from splashes and dust, without giving up a stainless steel finish.

Typical applications in the nautical field

A socket of this type is normally chosen to create or restore electrical connections where a dedicated, protected connection with materials suitable for the marine environment is useful. The presence of AISI 316 stainless steel and the declaration of protection for makes it suitable for installations where exposure to splashes and harsh conditions is a factor to consider.

The configuration 4 wires and the wording 3 + earth help guide the choice when a specific pole arrangement must be respected in your system. During design or maintenance, it is important to verify that the mating counterpart is consistent with the selected socket.

When to choose it

• For maintenance or replacement of an existing socket with the same configuration.
• For new installations where a socket with IP56 protection and components indicated as watertight is desired.
• When a solution with is preferred stainless steel finish and contacts in nickel-plated brass.

Operational advantages

• Declared protection: IP56 and indication of waterproof sealing, useful for exposed environments.
• Materials oriented for nautical use: AISI 316 stainless steel and glass-filled thermopolymer body, designed to withstand the typical stresses of onboard use.
• Nickel-plated brass contacts: common solution for electrical connections where continuity and contact reliability over time are sought (depending on correct installation and maintenance).
• Configuration clarity: 4 wires and 3 + side, useful to reduce ambiguity when choosing a replacement.

Use and installation notes

For a correct and lasting result, it is advisable that the installation be carried out by competent personnel, respecting good wiring practices and the manufacturer's instructions. Before purchase, always verify the correspondence between pole configuration, contact type (male/female) and the intended mating component.

Important notes (selection and compatibility)

• Coupling: the socket is designed to be paired with a compatible plug of the same series/configuration. In the related options, a 4-wire plug to be paired with socket 14.487.01 (female contacts, IP56) is indicated.
• Contact: this sheet refers to the variant “4-wire socket ... male contacts”. Check the necessary counterpart in your system.
• Protection: The declared IP rating refers to the product as specified; overall protection also depends on assembly, cable glands, and correct closure/mating.

Routine maintenance

In marine environments, it is good practice to periodically check the condition of the contacts and the integrity of the sealing parts, keeping the mating surfaces clean. In case of signs of wear or oxidation, intervene according to appropriate procedures and with correct spare parts.
