Common busbar 150 A - 10 terminals

This is an electrical component from Blue Sea Systems, model 2301-BSS, designed to centralize ground or negative connections (current returns) aboard vessels. It simplifies wiring and organizes electrical distribution for auxiliary circuits.

Its main function is to group the ground or negative connections of multiple electrical devices (such as lighting, pumps, VHF radios, or other instruments) to ensure organized and secure power distribution.

This busbar is designed to handle a maximum current of 150 amperes (150 A).

It has 10 connection terminals, allowing up to 10 separate circuits to be grouped on a common ground.

Yes, this busbar is specifically designed for the marine environment. It is certified compliant with marine safety standards, particularly for protection against ignition of flammable gases.

The 2301-BSS busbar is certified compliant with Directive 94/25/EC (amended by 2003/44/EC) for recreational craft and meets ISO 8846 standards. These certifications ensure protection against ignition of surrounding flammable gases.

Yes, the 2301-BSS model is certified to provide protection against ignition of surrounding flammable gases, a critical safety requirement in marine environments.

It is intended for basic electrical installations and circuit extensions on small to medium-sized vessels, where consolidation of grounding points is required without complex network features.

This busbar provides a simple, direct approach to managing return currents (common ground). Unlike intelligent NMEA 2000 junction boxes or advanced battery management systems, it does not offer network features or intelligent data management.

The bus bar must be mounted on a flat and stable surface using screws. The ground cables from the various devices are then connected to the 10 available terminals.

Installation typically requires basic tools such as a screwdriver to tighten terminals and crimping pliers to prepare cable lugs.

It must be installed in a dry, accessible location, protected from direct water spray, while being close to the equipment it powers to minimize cable length.

It is essential to ensure the power supply is cut off before any handling. The recommended tightening torque for the terminals must also be respected to ensure a secure connection and prevent overheating.

Yes, busbars of this type are passive components and are generally compatible with marine 12V, 24V or even 48V electrical systems, provided the total current does not exceed 150 amperes.

Yes, it is designed to consolidate the ground connections of various marine equipment such as lighting, pumps, VHF radios, navigation instruments, etc., provided their combined return current does not exceed 150 A.

It is compatible with standard marine cables, provided they are fitted with appropriate terminals for the busbar terminals and that their cross-section is suitable for the current they must carry.

This specific model has 10 fixed terminals. If more terminals are required, another busbar should be added or a Blue Sea Systems busbar model with a higher terminal count should be used.
