Circuit breaker series 285 - Surface mount 30 A

A Blue Sea Systems 285 Series circuit breaker is a circuit protection device designed for marine environments. It protects electrical equipment from overcurrents and short circuits, ensuring the safety of onboard systems. This model is specifically designed for surface mounting.

This Blue Sea 285 series circuit breaker has a rated current of 30 amperes (30 A). It is designed to provide reliable thermal protection for continuous loads up to this value.

Yes, this circuit breaker is manually resettable. After tripping due to an overload or short circuit, it can be reset by operating the lever or reset button without requiring a fuse replacement.

This circuit breaker is suitable for maritime electrical installations operating at 12 V and 24 V. It is designed to effectively protect circuits in these environments.

The main difference is that a circuit breaker, such as the 285 series, can be manually reset after tripping, whereas a fuse must be replaced once it has blown. The circuit breaker offers a more practical and cost-effective solution in the long term.

Yes, Blue Sea Systems 285 series circuit breakers are specifically designed for marine environments. They are typically splash-proof and ignition-protected to ensure reliability and durability onboard. They are often rated IP67, meaning they are protected against temporary immersion.

Yes, Blue Sea Systems 285 series circuit breakers are designed to be ignition-protected per SAE J1171 standards, making them safe for use in engine compartments or other areas where flammable vapors may be present. This feature is critical for marine safety.

This circuit breaker provides thermal protection against overcurrents and short circuits. It is designed to trip automatically when the current exceeds its rated capacity of 30 A, thereby protecting equipment and wiring.

The Series 285 circuit breaker is a cornerstone of the Blue Sea Systems range and is suitable for primary or secondary circuit protection applications. It is ideal for standard switching needs in various marine electrical configurations.

The 285 series stands out for its robustness, simplicity, and efficiency for standard switching needs. Compared to the C series, it is generally larger but offers reliable protection and is often chosen for its ease of surface mounting and manual reset.

Blue Sea Systems 285 series circuit breakers are designed to operate across a wide temperature range, typically from -40°C to +85°C. This ensures reliability in the varied environmental conditions encountered in marine environments.

The housing of this circuit breaker is typically made from impact-resistant, UV-stable thermal plastic, designed to withstand harsh marine environments, including exposure to sunlight and saltwater.

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.

For installation, you will typically need basic tools such as a screwdriver (suitable for mounting screws and terminals), wire strippers and crimping pliers for cables, as well as connectors compatible with the circuit breaker terminals. A multimeter can be useful for checking connections.

The 285 series circuit breakers typically use 1/4"-20 stud terminals. The recommended tightening torque for these terminals is 50 in-lb (approximately 5.65 Nm). It is critical to adhere to this specification to ensure a safe and reliable electrical connection.

This circuit breaker can be installed in various locations on a boat, including an electrical panel, near the devices to be protected, or in an engine compartment thanks to its ignition protection. The location must be easily accessible for manual reset.

Given that this circuit breaker is designed for marine environments and provides IP67 protection (against splashes and temporary immersion), additional housing is not always necessary for basic protection. However, for enhanced protection against physical impacts or prolonged exposure to extreme conditions, a housing may be considered.

The 1/4"-20 stud terminals on this circuit breaker are designed to accept appropriately sized ring terminals. It is critical to use cables with a cross-section suitable for the 30A rating and to crimp the terminals correctly to ensure a robust and secure connection.

Yes, this 285 series circuit breaker is fully compatible with marine electrical systems operating at 12V and 24V, making it versatile for most nautical applications.

Yes, you can replace a 30A fuse with this 30A circuit breaker, provided the mounting space and connections are suitable. The circuit breaker has the advantage of being resettable, avoiding the replacement of consumable components.
