Srovės saugiklis 187 serijos – paviršinis montavimas 120 A

The primary function of this circuit breaker is to protect marine DC electrical circuits against overcurrent. It detects excessive loads and automatically disconnects the circuit to prevent damage to equipment and cables.

This circuit breaker is rated for a nominal current of 120 amperes. This means it is designed to handle continuous loads up to 120 A and will trip if this value is exceeded.

The 187 series circuit breaker protects equipment by automatically disconnecting the circuit when it detects an electrical overload. This rapid action prevents excessive currents from damaging connected devices or causing overheating in the electrical system.

Yes, the BLUE SEA 187 series circuit breaker is manually resettable. After it has tripped due to an overload and the issue has been resolved, it can be reset simply by operating its lever, without requiring replacement.

Compared to a fuse, this circuit breaker offers several advantages:

Resettable: It can be manually reset after tripping, unlike a fuse which must be replaced.Convenience: It eliminates the need to carry spare fuses.Reliable protection: It provides consistent protection without the risk of incorrect rating when replacing.

Yes, this circuit breaker is specifically designed to operate in demanding marine environments. Its design makes it resistant to vibration and corrosion, ensuring reliability even in harsh conditions.

The BLUE SEA 187 series circuit breaker is designed to operate reliably across a wide temperature range, typically from -40°C to +85°C. This ensures its dependability in the diverse climatic conditions encountered at sea.

Yes, the BLUE SEA 187 series circuit breaker is designed with materials and finishes that provide excellent corrosion resistance, a key feature for long-term use in harsh marine saltwater environments.

Yes, the BLUE SEA 187 series circuit breaker has a reset lever that also serves as a trip indicator. When it trips, the lever moves to a visible position to indicate that the circuit has been opened due to an overload.

The main difference lies in the mounting type. This model is a surface-mounted circuit breaker, meaning it is fixed directly onto a bulkhead or panel. A flush-mounted circuit breaker, on the other hand, requires a cutout in the panel so that most of its body is hidden, leaving only the front face visible.

This circuit breaker is a surface-mount model. This means it is designed to be fixed directly onto a flat surface, such as a bulkhead or panel, without requiring complex cutting for installation.

Installing this circuit breaker, while simplified by its surface-mount design, must be performed by someone with marine electrical knowledge. It is essential to comply with wiring and safety standards to ensure correct operation and avoid any risk.

The surface-mount circuit breaker can be installed on various flat and stable surfaces, such as bulkheads, electrical panels, control panels, or inside engine compartments, provided the location is dry and protected from direct water spray.

The exact mounting dimensions are available on the technical drawing provided with the product (often the image "02 - Technical Detail"). It is recommended to consult this diagram to know the precise dimensions and hole spacings before installation.

Yes, it is mandatory to completely disconnect all electrical power sources (batteries, chargers, etc.) from the relevant circuit before installing or servicing the circuit breaker. This safety measure is essential to prevent electric shock or short-circuit risks.

This circuit breaker is compatible with direct-current (DC) electrical systems commonly used in marine applications. It is typically designed to operate with voltages of 12V DC, 24V DC, and up to 32V DC.

The 120 A circuit breaker is recommended for protecting high-current circuits on board. It is commonly used for equipment such as:

Voltage converters (inverters)Bow thrustersWindlassesBattery charging systemsOther high-current demand equipment.

Yes, this 187 series circuit breaker is designed to be compatible with 24V DC and 32V DC systems, in addition to 12V DC systems. Its robust design ensures effective protection across these different DC voltage levels.
