Waterproof plug plus 3-pole socket – code: 14.387.03 – Osculati

Watertight plug + 3-pole Osculati socket (code 14.387.03)

The watertight plug with 3-pole socket Osculati, code 14.387.03, it is a solution designed to create practical and neat electrical connections in nautical and onboard plant engineering fields. The construction is described as well made and highly reliable, with a body made of chromed brass, material chosen for its robustness and suitability for contexts where exposure to moisture and splashes may be a factor to consider.

The format “socket + plug” allows setting up a complete connection point, useful when a separable connection is desired for maintenance, storage, or to quickly connect/disconnect an onboard utility. The 3 poles configuration is suitable for systems requiring three contacts, maintaining a compact and functional setup.

Typical applications (nautical and onboard plant engineering)

This waterproof plug with socket is suitable for applications where an electrical connection is separable and designed for environments where moisture may be present. In nautical contexts, it can be useful, for example, to set up connections between parts of the system that you want to be able to disconnect easily during interventions or inspections.

Examples of use

• Creation of a connection point between wiring, with the possibility of disconnection.
• Connections on panels or technical areas where a tidy solution is useful and easily inspectable.
• Applications where the cable passage and the base size (Ø 46 mm) are compatible with the available space.

Operational advantages

• Complete solution: the socket + plug pairing simplifies component selection and connection setup.
• Construction in chrome-plated brass: suitable for technical use and good mechanical resistance.
• 3-pole configuration: useful when the system requires three dedicated contacts.
• Neat cable management: the reference to the Ø cable helps to select the correct passage during installation.

Usage and installation notes

Before installation, check that the configuration at 3 poles is consistent with the intended wiring and that the maximum current 20 A is suitable for the application. Also check the available space for the base (Ø 46 mm) and the cable compatibility with the passage (Ø 9 mm).

Good practices

• Arrange the wiring neatly, avoiding mechanical stress on the cable near the connection.
• During maintenance, disconnect the power before working on the connector.
• For a correct choice, always refer to the Osculati code 14.387.03 in case of reorder or comparison with variants (e.g. different number of poles).
