Waterproof thermal switch 100 A – code: 02.752.10 – Osculati

100 A Osculati thermal switch fuse (code 02.752.10)

The’100 A thermal switch fuse Osculati, identified by code 02.752.10, , is a component designed for the management and protection of electrical lines in nautical and plant engineering fields. Its uniqueness lies in combining in a single device the function of switch and that of fuse-type protection, with the convenience of being resettable and disconnectable via lever.

Thanks to the construction stagna and the classification IP67 Weatherproof, it is suitable for installations where splashes, humidity, or challenging environmental conditions typical of onboard systems may be present. It is a neat and professional solution for those who want an easily accessible disconnection and protection point, without having to replace a fuse after intervention.

Main features and details

This thermal switch is designed for practical and functional use in panels and power lines, with attention to protection and operational continuity. Below are the available details for this model.

Combined function: switch + protection

• Resettable: after tripping, it can be restored without replacing components.
• Disconnectable via lever: allows the line to be interrupted simply, also useful as disconnection during maintenance or checks.
• Function equivalent to fuse and switch: integrates protection and control in a single point of the system.

Sealing and environmental protection

• IP67 Weatherproof: suitable for installations where protection against dust and temporary immersion is required.
• Watertight structure: designed for environments exposed to humidity and splashes, typical of nautical applications.

Electrical and operating data (from product sheet)

• Maximum load: 100 A.
• Allowed voltage: max 48 V.
• Operating temperature: from -32° to +92°.
• Electrical terminals: 3/8″.

Standards declared by the manufacturer

The product is indicated as manufactured in accordance with USA standards SAE J1171 / SAE J1625.

Typical applications (nautical and onboard plant engineering)

A thermal switch like this is chosen when reliable and easily manageable protection is needed, with a more compact size and cleaner system logic compared to separate solutions. Some recurring uses include:

• Power lines where a manual break point and resettable protection are desired.
• Onboard systems subject to moisture or splashes, where IP67 sealing is an important requirement.
• Panels and boards where it is useful to quickly disconnect a line for checks or maintenance.
• Electrical distribution on devices that require a sealed and easy-to-handle component.

The combination of lever control and thermal protection makes it suitable for contexts where quick reset and operational simplicity are important, especially when access to components is not always immediate.

Benefits for installers and maintenance personnel

This Osculati model offers a series of practical advantages, particularly appreciated in professional installations and in the maintenance of onboard electrical systems.

Quick reset without replacements

Being resettable, after an intervention it is not necessary to replace a fuse. This can simplify spare parts management and reduce reset times, especially when operating in technical spaces or during navigation.

Immediate disconnection via lever

The ability to disconnecting via lever allows direct interruption of the line. This is useful during:

• system checks;
• maintenance interventions;
• isolation of a line before working on a device.

Suitable for exposed environments

The classification IP67 Weatherproof and construction stagna make the component suitable for installations where the environment can be critical. In the nautical field, this means greater peace of mind in choosing the installation point, provided it is done correctly.

Neat installation with dedicated terminals

The presence of 3/8″ electrical terminals allows a consistent connection with wiring and terminals compatible with this size, promoting a clean and professional installation.

Usage and installation notes

To achieve a safe and lasting result, it is advisable to consider some practical aspects before installation and during use.

Verification of system parameters

• Ensure that the line falls within the allowed voltage (max 48 V).
• Correctly evaluate the maximum load 100 A in relation to the line and the user.
• Consider the operating temperature declared, depending on the mounting point.

Connections and terminals

The product is indicated with 3/8″ terminals: during assembly it is appropriate to use suitable connection components (compatible terminals and hardware) and to perform correct tightening, avoiding mechanical stresses on the cables.

Positioning and protection

The protection IP67 supports use in exposed environments, but good practice is still to install the component in a position that reduces direct exposure and facilitates access to the lever for disengagement and reset operations.

Operational note

In case of disengagement, before resetting it is advisable to identify and resolve the cause that led to the protection intervention. This approach helps keep the system in proper condition and prevents repeated interventions.
