Three-phase 4-wire plug 63 A – code: 14.587.09 – Osculati

4-wire three-phase plug 63 A Osculati (code 14.587.09)

The 4-wire three-phase plug 63 A Osculati, code 14.587.09, is a component designed to make electrical connections in nautical and plant engineering fields where a robust and protected connection is required. The construction is oriented for use in environments exposed to humidity and splashes: the plug is indicated as completely waterproof and designed to work reliably under typical onboard conditions.

The body is made of high-strength glass-filled thermopolymer, while the contacts are made of nickel-plated brass. The plug is described as to be mated with socket 14.487.09 and features female contacts. Indicated degree of protection: IP56.

Features and construction details

Product configuration and identification

• Type: three-phase plug
• Wires: 4
• Rated current: 63 A
• Indicated voltage: 230 V
• Poles: 3 + earth
• Supplier code: 14.587.09
• Brand / supplier: Osculati S.r.l.

Protection and resistance in marine environments

The plug is declared watertight and with IP56 protection rating, a useful feature when the connection may be subject to splashes, moisture, and dust. In nautical applications, protecting the connection interface is a key aspect to reduce the risk of infiltration and maintain contact quality over time.

Materials

• Body: high-strength glass-filled thermopolymer
• Contact: nickel-plated brass

The choice of a reinforced thermopolymer body is typical for components intended for practical and continuous use, while the nickel plating of the contacts contributes to good surface protection in contexts where oxidation may be a factor to consider.

Series coupling and compatibility

This connector is indicated as to be mated with socket 14.487.09. For correct installation, it is important to verify that the counterpart is indeed the intended model and that the configuration (poles and wiring) matches the system.

Typical applications

The 4-wire three-phase plug is suitable for uses where power connections are used in nautical or plant engineering fields. In particular, it can be employed in:

• Onboard systems for electrical connections in technical areas or zones subject to humidity.
• Mooring maintenance and refitting, when replacing worn or no longer reliable connectors, maintaining compatibility with the dedicated socket.
• Panels and power lines where a three-phase connector with IP56 protection is required (according to the system design).

In case of doubts about the choice of connector (pole scheme, cable section, tightening method, etc.), it is advisable to refer to the system documentation or the installation technician.

Operational advantages

Protected connection suitable for outdoor use

The combination of protection for and IP56 makes the product suitable for contexts where the connection may be exposed to splashes or non-ideal environmental conditions. This helps maintain a more stable connection over time, especially when the plug is connected and disconnected during normal onboard operations.

Materials oriented towards durability

The glass-filled thermopolymer is designed for practical and durable use, while the nickel-plated brass contacts are a common solution to reduce the impact of oxidation and surface wear in demanding environments.

Simple choice in case of replacement

When replacing an existing plug, having a clear reference such as the code 14.587.09 and the mating indication with the socket 14.487.09 helps reduce selection errors and maintain consistency with the installed component series.

Usage and important notes

Installation

The installation of a three-phase plug requires attention to wiring and conductor tightening. To preserve the declared protection features (waterproof / IP56), it is important to:

• carry out the assembly carefully, respecting the orientation and closing of the body;
• check that the coupling with the socket is complete and correct;
• periodically check the condition of the connection, especially in a marine environment.

Useful combinations

Within the same accessory family there is a yellow PVC waterproof cap suitable for 14.587.06 and 14.587.09. The use of a protective accessory can be useful when the plug is not connected, to reduce the exposure of the contact area to external agents (according to the system requirements).

Checks before purchase

• Confirm that the counterpart is the socket 14.487.09.
• Check that the configuration 4 wires and 3 + earth is consistent with the system.
• Ensure that the protection requirements IP56 are adequate for the intended installation location.

For specific onboard needs or replacements on existing systems, it is good practice to compare the product code and pole configuration with the component already installed.
