Aizsargsērējs sērija 285 - 100 A panelimontāžai

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 simplifies its integration into electrical panels, control consoles, or other flat surfaces, providing a clean and accessible installation.

The Blue Sea 285 series circuit breaker is equipped with a manual reset lever. After a trip caused by 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 salt 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 ignition-protected to SAE J1171 standards. It is safe for installation in boat engine compartments where flammable vapors may be present.

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

The 285 series is often selected 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 favored for applications requiring more precise overload protection across a wider temperature range.

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

Medium to large inverters.Powerful battery chargers.High-power distribution systems.Small to medium bow thrusters or windlasses.

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 circuit 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 in recreational vehicles (RVs). Its robustness, vibration resistance, and ability to protect high-consumption DC systems make it an ideal choice for these applications.

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

Use cables with the correct cross-section for 100 A current. Tighten connections to M6 terminals properly. Follow polarity (if applicable, although DC circuit breakers are often non-polarized, it is good practice to adhere to wiring conventions). Ensure the circuit breaker is installed in an accessible location for resetting and maintenance. Consult a professional if you are unsure about your marine electrical skills.
