Rafmagnsrofi BLUE SEA 285 - 60 A, fyrir skjásetning

The BLUE SEA 285 series thermal circuit breaker is a circuit protection device designed for marine environments. It automatically interrupts the current in case of overload or short circuit to protect onboard electrical equipment. It is characterized by its ability to be manually reset after tripping, unlike a fuse which must be replaced.

This circuit breaker has a rated current of 60 amperes (A). This means it is designed to operate continuously with a current up to 60 A and will trip if the current exceeds this value excessively or for a prolonged period.

Yes, absolutely. The BLUE SEA 285 series circuit breaker is specifically designed to withstand harsh marine conditions, including humidity, salt spray, and vibrations. Its construction ensures optimal reliability at sea.

Yes, the BLUE SEA 285 series circuit breaker is spark-proof according to SAE J1171 and UL 1500 standards. This means it is designed not to generate sparks or excessive heat that could ignite fuel vapors in an engine compartment, making it safe for use aboard boats.

The main function of this circuit breaker is to protect electrical circuits and connected equipment from damage caused by overcurrent and short circuits. It acts as a safety switch that automatically cuts off the power supply when an abnormal condition is detected.

The main difference is that a circuit breaker is a reusable device. After tripping due to an overload or short circuit, it can be manually reset once the cause of the issue is resolved. A fuse, on the other hand, is a single-use device that must be replaced after melting to interrupt the circuit.

The interrupting rating (AIC - Ampere Interrupting Capacity) of this circuit breaker is 3000 amperes (A) at 48V DC. This indicates the maximum current the circuit breaker can safely interrupt without sustaining permanent damage.

This circuit breaker is designed to operate reliably across a wide temperature range, typically from -40°C to +85°C. This thermal robustness ensures performance in various marine weather conditions.

This circuit breaker is designed for panel mounting. It fits into a standard cutout on an electrical panel and is typically secured with screws. Panel mounting allows for a clean installation and easy access to the reset button.

This circuit breaker uses threaded studs for cable connections. These studs provide a secure and robust connection, ideal for medium to high power applications in a marine environment.

For a 60 A circuit breaker from the 285 series, the connection studs are typically 1/4"-20 (UNC thread) or M6. It is important to check the exact specifications of the model to confirm the stud size for proper use of the terminals.

Although the circuit breaker itself is robust, it is strongly recommended to use insulating caps for the terminals to protect the connections against accidental short circuits, corrosion, and water splashes, thereby improving the safety and durability of the installation.

When properly mounted on a panel, the 285 series circuit breaker generally provides protection against water spray and dust, with an IP67 rating for the front side. This means it is protected against temporary immersion and dust, making it ideal for marine environments.

This circuit breaker is designed for direct current (DC) systems. The maximum supported voltage is typically 48V DC. It is compatible with common marine electrical systems of 12V, 24V or 32V DC.

This 60 A circuit breaker is recommended for protecting medium-power circuits on board vessels. This includes applications such as battery charging systems, high-flow bilge pumps, small to medium windlasses, inverters, or clusters of navigation and communication equipment.

Yes, absolutely. This circuit breaker is compatible with 12V and 24V DC systems. Its maximum voltage rating of 48V DC means it can be safely used with lower voltages without compromising performance or protection.

It is possible to replace a circuit breaker from another BLUE SEA series, but it is crucial to verify the compatibility of the rated current (amperage), maximum voltage, mounting type (panel in this case), and physical dimensions to ensure correct and safe installation. The 285 series offers a good balance between compactness and breaking capacity.

After a trip, the circuit breaker can be reset manually. Simply press the reset button, which will have popped out. Before resetting, it is recommended to identify and correct the cause of the overload or short circuit to prevent immediate tripping again.
