Kaitselüliti seeria 285 – paneelipaigaldus 50 A

The primary role of this circuit breaker is to protect your marine electrical circuits against overcurrent and short circuits. It automatically interrupts the electrical flow in case of a problem, thereby preventing damage to equipment and fire risks aboard your vessel.

This specific BLUE SEA 285 series circuit breaker has a rating of 50 amperes (50 A). This means it is designed to protect circuits with a nominal current not exceeding this value.

Yes, this circuit breaker is manually resettable. Unlike fuses, which must be replaced after melting, this circuit breaker can be reactivated by moving its lever or pressing its button once the cause of the trip (overload or short circuit) has been identified and resolved.

This circuit breaker is equipped with thermal protection. It detects overcurrents by measuring the heat generated by excessive current, allowing it to trip in case of prolonged overload or short circuit.

Yes, the BLUE SEA 285 series circuit breaker is specifically designed for demanding marine environments. It is manufactured with corrosion-resistant materials and complies with maritime standards, ensuring reliability and durability aboard your boat.

This circuit breaker is designed to operate across a wide temperature range, typically from -40°C to +85°C, making it suitable for the varied climatic conditions encountered at sea.

Exact dimensions for panel mounting are provided in the product technical drawing. It is designed with standardized dimensions for easy integration into most marine dashboards or distribution boxes.

Yes, Blue Sea Systems 285-series circuit breakers are generally compliant with SAE J1171 ignition protection standards, making them safe for use in boat engine compartments where flammable vapors may be present.

This circuit breaker is designed for panel mounting. This means it installs directly onto the surface of an electrical panel or bulkhead, with the front face visible and accessible for operation and resetting.

For installation, you will typically need basic tools such as a drill with a suitable bit for the mounting hole, a screwdriver for terminal connections, and possibly wire strippers and crimping pliers to prepare the electrical cables.

Electrical cables connect to the stud terminals of the circuit breaker. It is critical to respect polarity (input and output) and use appropriate lugs to ensure a secure, corrosion-free connection. Tighten the terminal nuts to the torque specified by the manufacturer to prevent loosening due to vibration.

Although the circuit breaker itself has no strict functional mounting direction for its internal mechanism, it is recommended to install it so that the lever or reset button is easily accessible and the (ON/OFF) indicators are readable for intuitive use.

The circuit breaker is usually supplied with the nuts and washers required to secure cables to the terminals. The specific hardware for panel mounting (screws, etc.) may vary and should be checked in the packaging or product instructions.

To ensure proper sealing when mounting on a panel, it is recommended to use a sealing gasket or appropriate marine sealant around the mounting opening, especially if the panel is exposed to spray or moisture. This protects the internal components from salt water.

Yes, this BLUE SEA 285 series circuit breaker is compatible with 12V and 24V DC electrical systems, making it versatile for most marine installations.

With a 50 ampere capacity, this circuit breaker is suitable for protecting medium-power circuits. This typically includes bilge pumps, fans, certain navigation lights, small inverters or converters, and other equipment requiring significant but not extreme current.

No, this BLUE SEA Series 285 circuit breaker is specifically designed for DC (direct current) systems. For AC (alternating current) applications, you must use circuit breakers designed and certified for AC systems, which have different specifications.

Yes, you can use this 50A circuit breaker to protect circuits with a rated current below 50A. However, for optimal and more precise protection, it is generally recommended to select a circuit breaker whose rating is as close as possible to the rated current of the device to be protected, without exceeding it.

Yes, this circuit breaker can replace a 50A fuse in a DC system, with the advantage of being resettable. Ensure the breaker's voltage and interrupting capacity specifications are suitable for your application and that the panel mounting is compatible with the fuse's location.

Blue Sea Systems' 285 Series circuit breaker typically has an interrupting rating (AIC) of 3000 amperes (3 kA) at 32V DC. This indicates its ability to safely interrupt a high short-circuit current without being damaged, ensuring the safety of your installation.
