Aizsargslēdzis sērijai 187 - Virsmas montāža 120 A

The main function of this circuit breaker is to protect marine DC electrical circuits from 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 a manually resettable circuit breaker. 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 during replacement.

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 effectively across a wide temperature range, typically from -40°C to +85°C. This ensures reliability in various marine climate conditions.

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 a marine saltwater environment.

Yes, the BLUE SEA 187 series circuit breaker has a reset lever that also serves as a tripping 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 directly fixed to 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 carried out by someone with marine electrical knowledge. It is essential to comply with wiring and safety standards to ensure proper 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 splashes.

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 centers before installation.

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

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:

DC-AC invertersBow thrustersWindlassesBattery chargersOther 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.
