Disjunctor serie 285 - Montaj panou 100 A

This thermal-magnetic circuit breaker is designed to provide reliable protection for DC electrical systems on boats and recreational vehicles. It protects main circuits or high-power loads, such as inverters, battery chargers, or high-power distribution systems, against overloads and short circuits.

The Blue Sea 285 series circuit breaker is specifically designed for direct current (DC) systems. It is compatible with voltages up to 48V DC, making it suitable for common marine installations (12V, 24V, 32V DC).

This model has a rated capacity of 100 Amperes (A). This means it is designed to operate continuously with a current up to 100 A and will trip if the current exceeds this value for a given period, thus protecting the circuit.

This circuit breaker is designed for panel mounting. This makes it easy to integrate into electrical panels, control consoles, or other flat surfaces, providing a clean and accessible installation.

The Blue Sea 285 series circuit breaker features a manual reset lever. After tripping due to an overload or short circuit, simply move the lever back to the 'ON' position once the cause of the issue has been identified and corrected. No fuse replacement is required.

Yes, absolutely. The Blue Sea 285 series circuit breaker is specifically designed to withstand the stresses of marine environments, including humidity, vibrations, and spray. Its robust design ensures operational longevity in these demanding conditions.

Yes, this circuit breaker is an excellent alternative to traditional fuses. It offers greater convenience thanks to its manual reset mechanism, eliminating the need to replace fuses after every overload or short-circuit event.

Yes, this circuit breaker is protected against ignition per SAE J1171. This makes it safe for installation in boat engine compartments, where the presence of flammable vapors could pose a risk.

The Blue Sea 285 series circuit breaker is designed to operate within a wide temperature range, from -40°C to +85°C. This thermal robustness ensures its reliability in various marine weather conditions.

The 285 series is often chosen for applications requiring robust protection in a compact form factor, particularly for circuits with high nominal currents where thermal-magnetic protection is preferred. The 187 series, while similar, may have different characteristics in terms of interrupting capacity or tripping type (e.g., hydraulic-magnetic in some versions) and is sometimes preferred for applications requiring more precise overload protection over a wider temperature range.

This 100 A circuit breaker is suitable for protecting high-power circuits on a boat, such as:

Medium to large inverters.Powerful battery chargers.High-power distribution systems.Bow thrusters or winches of small to medium size.

When properly mounted on a panel, the Blue Sea 285 series circuit breaker provides IP67 protection. This means it is fully protected against dust and can withstand temporary immersion in water (up to 1 meter for 30 minutes) without damage.

Yes, the reset lever of the Blue Sea 285 series circuit breaker also serves as a visual indicator. When the breaker trips, the lever moves from the 'ON' position to an intermediate or 'OFF' position, clearly indicating that the circuit has been interrupted.

Yes, in addition to marine applications, the Blue Sea 285 series circuit breaker is also well suited for use on recreational vehicles (RVs). Its robustness, vibration resistance, and ability to protect high-current DC systems make it an ideal choice for these applications.

For a secure installation, it is crucial to follow these points:

Use cables with the appropriate cross-section for the 100 A current.Tighten connections properly to M6 terminals.Respect polarities (where applicable; although DC circuit breakers are often non-polarized, it is good practice to follow wiring conventions).Ensure the circuit breaker is mounted in an accessible location for reset and maintenance.Consult a professional if you are unsure about your marine electrical skills.
