Jistič série 285 – povrchová montáž 60 A

The primary function of this circuit breaker is to protect marine electrical circuits from damage caused by overcurrent and short circuits. It automatically interrupts the current flow when an anomaly is detected, thereby protecting the connected equipment and wiring.

Yes, the BLUE SEA 285 series circuit breaker is specifically designed for marine environments. It is made with corrosion-resistant materials and complies with maritime standards, ensuring reliable and durable protection aboard your boat.

This circuit breaker has a rated current capacity of 60 amperes (60 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 for a given period, thus protecting the circuit.

This circuit breaker is designed for surface mounting. This means it is fixed directly onto a flat surface, such as an electrical panel or a bulkhead, using screws. This type of configuration makes installation easier.

Yes, Blue Sea’s 285-series circuit breakers are generally compatible with marine DC electrical systems operating at 12 V, 24 V, and even up to 32 V or 48 V. Verify the full technical specifications for the maximum supported voltage.

The main difference is that a circuit breaker can be manually reset after tripping due to overload or short circuit, whereas a fuse must be replaced once it has blown. Circuit breakers offer the convenience of reset and are often preferred for circuits frequently subject to temporary overloads.

To reset the circuit breaker after it has tripped, simply move the lever or reset button (usually a toggle switch) to the 'ON' position. First, ensure the cause of the trip (overload or short circuit) has been identified and corrected.

A 60 A circuit breaker is suitable for protecting a variety of high-consumption circuits and equipment on a boat, such as:

Electric windlassesPower invertersBow thrustersHigh-flow bilge pumpsMain power circuits for equipment groupsIt is essential to select the appropriate amperage based on the maximum load of the circuit to be protected.

Yes, Blue Sea’s 285-series circuit breakers are typically certified "ignition protected" per SAE J1171. This means they are designed not to produce sparks that could ignite fuel vapors in an engine compartment—a critical safety feature for marine applications.

The casing of this circuit breaker is typically made of thermoplastic. This material is chosen for its durability, resistance to impacts, UV rays, and corrosion, which is essential for prolonged use in a marine environment.

This circuit breaker is equipped with stud terminals, typically sized 1/4"-20. These terminals allow secure cable connections using appropriate lugs, ensuring good electrical contact and resistance to vibrations.

No, a circuit breaker performs the same protective function as a fuse. Therefore, it is not necessary to use an additional fuse holder for the same circuit. The circuit breaker has the advantage of manual reset.

Although it can technically cut power, its primary function is protection against overloads and short circuits. For a main switch, it is often preferable to use a battery switch or a circuit breaker designed specifically for frequent switching and complete system isolation.

Blue Sea 285 series circuit breakers are designed to operate across a wide temperature range, typically from -40°C to +85°C. This robustness allows them to function reliably in the various climatic conditions encountered at sea.

The choice of the circuit breaker's amperage must match the maximum continuous load of the circuit to be protected, while being below the current capacity of the circuit's wiring. It is recommended to size the circuit breaker at approximately 125% of the continuous operating current of the highest-rated device or circuit, without exceeding the wire's capacity.

The interrupting rating (AIC - Amperage Interrupting Capacity) of this circuit breaker is typically 3000 A at 32V DC. This indicates the maximum short-circuit current the breaker can safely interrupt without damage.

For installing this circuit breaker, you will need basic marine electrical tools, such as:

A screwdriver (for mounting screws and terminals)
A crimping tool (for cable lugs)
A wire stripper
A drill (for mounting holes if necessary)
Ensure you use insulated tools and disconnect power before any work.

It is not recommended to paint the circuit breaker housing. The paint could alter the material's properties, potentially compromising its UV resistance, heat dissipation, or compliance with standards (such as ignition protection). It is best to keep the product in its original state to ensure performance and safety.
