Typical applications in onboard systems

A battery disconnect switch is a central element in energy management onboard, as it allows switch power supply to be cut off when the boat is stationary, during maintenance interventions, or when it is desired to secure a circuit. This model, thanks to its construction and flange mounting, is suitable for installations where having an accessible and protected control point is important.

When it is particularly useful

• Electrical system maintenance: circuit isolation before working on loads, wiring, or components.
• Storage: battery disconnection to reduce unwanted consumption and manage the system in an orderly manner.
• Operational management: possibility to quickly interrupt power supply according to onboard needs.

Operational advantages

Protected control and key management

The equipment with waterproof PVC cap helps protect the control area, while the presence of two included keys simplifies daily management (one in use and one spare). For replacement needs, the replacement key 14.385.34.

Neat panel mounting

The flange mounting allows a clean and stable installation, useful when you want to integrate the battery switch in a panel or on a bulkhead, maintaining a professional appearance of the system.

Declared regulatory references

The declaration of CE approval according to the directive 2013/53/EU (UNI EN ISO 8846) is an important informational element for those operating in the nautical field and wishing for components with explicit regulatory indications in the product documentation.

Usage and installation notes

Positioning on the positive cable

The product is indicated as mandatory device to be mounted on the positive cable. During installation, it is good practice to plan the disconnection point so that it is accessible and consistent with the system logic (for example near the battery compartment or at a dedicated control point), maintaining neat wiring.

Mechanical compatibility of connections

Before mounting, check the compatibility of terminals/lugs with the 10 mm studs and the available space for panel installation, also considering the flange size (Ø 66 mm) and the overall dimensions of the component.

Spare parts and management over time

For component management over time, the replacement key 14.385.34. is available. Keep one key in a safe and easily accessible place on board to simplify operations if necessary.

Note

For correct installation and compliance with best practices, follow the manufacturer's instructions and the applicable regulations for the onboard system.
