Aizsargsērējs sērija 187 — Virsmas montāžas 150 A

The Blue Sea Systems 187 Series circuit breaker is an electrical protection device designed specifically for marine environments. It protects high-current circuits from overloads and short circuits, ensuring the safety of equipment and the vessel's electrical system.

The primary function of this circuit breaker is to quickly cut off power to a circuit when an overload or short circuit is detected. This prevents damage to connected equipment and reduces the risk of fire or system failure.

This specific model, the 7148-BSS, has a rated current of 150 amperes (A). This means it is designed to protect circuits where the normal current does not exceed this value.

The Blue Sea 187 series circuit breaker is designed to operate with electrical systems up to a maximum voltage of 48 Volts DC (direct current).

The main difference is that this circuit breaker offers a manual reset function. After a trip due to overload or short circuit, it can be reset manually once the issue is resolved, unlike a fuse which must be replaced after melting.

Yes, this circuit breaker is specifically designed by Blue Sea Systems for marine applications. It is known for its robustness and reliability in harsh environmental conditions.

This circuit breaker is designed to operate effectively across a wide temperature range, from -40°C to +85°C, making it suitable for various marine climates.

Yes, the Blue Sea 187 series circuit breaker is ignition protected in accordance with SAE J1171 and ISO 8846 standards. This means it is designed not to emit sparks that could ignite vapors or gases in potentially explosive environments, such as engine compartments.

The housing of this circuit breaker is made of thermosetting plastic, a material known for its durability, heat resistance, and ability to withstand harsh marine environments.

This circuit breaker is designed for surface mounting. This means it is fixed directly onto a bulkhead or panel without requiring complex cutouts for flush installation.

Yes, its surface-mount design greatly simplifies installation. It can be directly fixed to a flat surface, reducing time and complexity compared to flush-mounted models.

This circuit breaker is fitted with 5/16"-18 stud terminals, providing secure connections for heavy-gauge cables.

This 150 A circuit breaker is ideally suited for protecting high-power consumption circuits on board, such as:

Powerful invertersElectric windlassesBow thruster systemsMain protection for major circuit branches

Yes, absolutely. This circuit breaker is designed for systems up to 48V DC, making it fully compatible and safe for use in 12V DC or 24V DC marine electrical systems.

Yes, this circuit breaker can replace a 150 A fuse, with the advantage of being resettable. Ensure the surface-mount type and terminal connections are compatible with the existing space and wiring.

Yes, this 150 A circuit breaker can be used to protect main circuits or high-current branch circuits in marine solar panel installations, particularly for charging systems or inverters handling high currents.
