High capacity battery switch selector – code: 14.905.00 – Osculati

High capacity battery disconnect switch Osculati (code 14.905.00)

The high capacity battery disconnect switch Osculati is a component dedicated to managing onboard electrical power, designed for those who want a reliable control for switch and divert the current between battery lines/banks in an orderly manner. It is a solution suitable for nautical and electrical systems, where continuity and connection safety are central aspects during use, maintenance, and storage periods.

This model is made with contacts completely in copper, stainless steel springs and polycarbonate casing, a combination aimed at robustness and resistance in technical environments. It also integrates a function of automatic interruption of the alternator current if the battery disconnect switch is operated before turning off the engine, a useful detail for the correct management of the system in real operational situations.

Features and construction details

Materials and structure

• Copper contacts for a solid electrical connection.
• Stainless steel springs, suitable for use in contexts where reliability and resistance of mechanical components are important.
• Polycarbonate casing, designed to protect the device body and its internal elements.

Alternator protection function

The device provides the’automatic alternator power cut-off in case the battery switch is activated before the engine is turned off. This feature is designed for more controlled system management when intervening on power disconnection.

Suitability for use

It is indicated as particularly suitable for diesel engines which, with large starter motors, require high amperages. In general, it is suitable for installations where a high-capacity battery switch with carefully designed components is required.

Available data (declared specifications)

• Max capacity (intermittent): 850 A
• Max capacity (continuous): 380 A
• Version: Universal 12/24 V
• Terminal Ø: 12 mm
• Pins: 12 mm
• Dimensions: 140x140x85 mm

Compliance

CE certified according to the regulation 94/25/EC.

Typical applications in nautical and plant engineering

A battery switch is commonly used to organize and control onboard power supply, especially when multiple loads and/or multiple batteries are present. This model, thanks to its “high capacity” design, is suitable for contexts where current demand can be significant, such as during starting or in systems with heavy loads.

Examples of use

• System disconnection during maintenance, storage, or interventions on wiring and loads.
• Management of multiple lines/banks (switch function) for a more orderly distribution of energy onboard.
• Systems with diesel engines and starter motors that require high currents.
• 12/24 V installations where a universal component is desired, without having to differentiate the model based on system voltage.

Operational advantages

Reliable connections and selected components

The use of copper for the contacts and stainless steel for the springs meets the need to have a component suitable for technical use, with attention to the quality of the parts subject to contact and stress.

Safer maneuver management

The function of automatic interruption of the alternator current in case of operation before engine shutdown is an element that supports a more correct management of disconnection maneuvers, reducing the risk of improper procedures during daily use.

Suitable for systems with high current demands

The declared capacities (intermittent and continuous) make this battery isolator switch a suitable choice when the system requires a component sized for significant currents, typical of some onboard starting and distribution configurations.

Usage and installation notes

To achieve a neat installation consistent with the onboard system, it is advisable to plan the placement of the battery isolator switch in an accessible, protected point compatible with the power cable routing. When selecting and mounting, always verify the correspondence between the system requirements and the available product data (capacity, dimensions, terminals).

Good practices (general)

• Install in an area that allows easy operation and periodic inspection.
• Ensure tightening and order of connections on the end fittings, avoiding mechanical stress on the cables.
• Before working on the system, adopt safety procedures and properly isolate the power supply.
• If in doubt about wiring diagrams and cable sizing, rely on qualified personnel.
