Marinco stainless steel three-phase 4-wire socket 63 A – code: 14.487.09 – Osculati

Marinco stainless steel three-phase 4-wire socket 63 A (Osculati 14.487.09)

The Marinco socket in AISI 316 stainless steel three-phase 4-wire is a solution designed for onboard electrical systems where robust, reliable components suitable for exposed environments are required. This model, identified by the Osculati code 14.487.09, it is suitable for installations in the nautical and plant engineering fields, with particular attention to protection against water ingress and the durability of materials over time.

The construction combines a structure in high-strength glass-filled thermopolymer with an external finish in AISI 316 stainless steel and nickel-plated brass contacts. The result is a component suitable for operational contexts where vibrations, salt spray, and frequent use require carefully selected materials and fittings. The socket is declared completely waterproof and with protection rating IP56.

Important note on component selection

This datasheet refers to the three-phase 4-wire socket with male contacts. When purchasing/checking the system, it is essential to select the correct component (socket/plug) and the configuration consistent with the planned wiring.

Typical applications (nautical and onboard plant engineering)

The Marinco stainless steel three-phase socket is commonly used in installations where a structured and protected electrical connection is needed, with materials suitable for use in marine environments.

• Onboard systems that require three-phase connections with 4-wire wiring.
• Connection points in exposed areas or subject to splashes, where IP protection and sealing are a practical requirement.
• Refitting and maintenance of existing systems, when you want to maintain components consistent with the Marinco/Osculati line.
• Technical installations on boats and related applications, where the resistance of materials (AISI 316 stainless steel and nickel-plated contacts) is a selection factor.

Main advantages

Material resistance in marine environments

The use of AISI 316 stainless steel contributes to good corrosion resistance in typical nautical contexts. The glass-filled thermopolymer is chosen for its robustness and stability, while the nickel-plated brass contacts are indicated to promote continuity and durability of contact over time, in repeated use conditions.

Protection against water and dust

The socket is indicated as completely waterproof and with IP56. This makes it suitable for installations where protection against the ingress of water and particles is an important operational aspect, for example in technical or external areas of the boat.

Professional solution for three-phase systems

The configuration three-phase 4-wire and the capacity 63 A place it among components intended for systems that require professional-level connections. The stainless steel finish and reinforced construction are elements especially appreciated in contexts where reliability and robustness are priorities.

Usage and operational notes

Coupling with the correct component

For proper operation, the socket must be coupled with the corresponding component of the same series and configuration (three-phase, 4-wire, compatible contacts). Before installation, always check:

• that the pole configuration it is consistent with the system;
• which nominal voltage and current are compatible with the application;
• that the type of contact (male/female) corresponds to the component to be coupled.

Installation and maintenance

In the nautical field, it is good practice to perform installation and checks with qualified personnel, respecting system procedures and manufacturer instructions. To maintain sealing performance and contact quality over time:

• periodically check the general condition of the socket and the mounting area;
• keep the mating surfaces and contacts clean, avoiding contamination;
• ensure that the connection is always complete and correct before use.
