Waterproof thermal switch 150 A – code: 02.752.15 – Osculati

150 A waterproof thermal switch Osculati (code 02.752.15)

The’waterproof thermal switch Osculati 150 A (code 02.752.15) is a component designed for the management and protection of electrical circuits, especially in contexts where a device resettable and practical to operate. Thanks to the lever dedicated, it can be tripped and reset easily, simultaneously performing the function of switch hydraulic fuse-type protection.

The production in version stagna makes it suitable for installations where protection against external agents is required. It is suitable for systems with allowed voltage up to 48 V and for use in a wide range of operating temperatures.

Main features and details

Combined function: switch + protection

This thermal switch is designed to offer simple circuit management:

• Resettable: after tripping, it can be reset without replacing elements as happens with a traditional fuse.
• Disconnectable via lever: allows you to conveniently interrupt the circuit when necessary.
• Double function: simultaneously performs the functions of fuse and switch, simplifying system management.

Sealing and protection

The product is declared IP67 Weatherproof, a useful feature for installations where high protection against dust and water ingress is required.

Declared technical data

• Max load: 150 A
• Allowed voltage: max 48 V
• Operating temperature: from -32° to +92°
• Electrical terminals: 3/8″

Reference standards

Manufactured in accordance with USA standards SAE J1171 / SAE J1625.

Typical applications (nautical and onboard plant engineering)

• Protection of power supply lines in low voltage systems (within declared limits).
• Circuit disconnection via lever during maintenance, inspections, or interventions on the system.
• Installations where a device is useful resettable to reduce operational downtime related to fuse replacement.
• Uses in environments where protection for and protection from external agents are important requirements.

Note: the choice of correct sizing and proper installation position depends on the system design and actual loads. In case of doubt, it is advisable to refer to the onboard electrical diagram or your trusted technician.

Operational advantages

Quick reset and simplified management

The ability to reset make this component practical in all situations where you want to restore the circuit without immediate replacement intervention. The lever also allows direct trip management, useful as support for control and maintenance operations.

Neat solution for the system

A device that integrates interruption and protection functions can contribute to a more streamlined configuration of the panel or line, reducing the need for separate components (depending on the system design).

Suitable for exposed environments

The classification IP67 Weatherproof It is a relevant element for installations where high protection against infiltration and challenging environmental conditions is required.

Usage and installation notes

General indications

• Verify that voltage and power of the system fall within the declared limits (max 48 V, 150 A).
• Consider the range of operating temperature (from -32° to +92°) in relation to the installation point.
• Ensure correct connection to the 3/8″ terminals with suitable components (cable lugs, tightening, protections), according to good wiring practices.
• During assembly, follow the manufacturer's instructions and safety procedures for working on electrical systems.

When to choose the 150 A version

This variant is identified by the max load 150 A. If you are comparing multiple versions of the same family (with different load values), select the one consistent with the sizing planned for your system.
