Jistič série 285 – povrchová montáž 30 A

A Blue Sea Systems 285 series circuit breaker is a circuit protection device designed for marine environments. It protects electrical equipment from overcurrent 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 overcurrent or short circuit, it can be reset by operating the lever or reset button without requiring the replacement of a fuse.

This circuit breaker is suitable for marine 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 the marine environment. They typically feature splash and ignition protection to ensure reliability and durability on board. 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 the equipment and wiring.

The 285 Series 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 provides 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 their reliability in the varied environmental conditions encountered in marine environments.

The housing of this circuit breaker is typically made from impact- and UV-resistant 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 generally need basic tools such as a screwdriver (suitable for mounting screws and terminals), wire strippers and crimping pliers for cables, as well as connectors matching 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 torque for these terminals is 50 in-lb (approximately 5.65 Nm). It is important 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 the marine environment and provides IP67 protection (against splashes and temporary immersion), an additional enclosure is not always necessary for basic protection. However, for enhanced protection against physical shocks or prolonged exposure to extreme conditions, an enclosure 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 current and to properly crimp the terminals 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 parts.
