Jistič série 187 – povrchová montáž 30 A

This is an essential electrical component designed for protection of marine circuits. It provides automatic current interruption in case of overload or short circuit, thereby protecting connected equipment and the integrity of the vessel's electrical system.

Its primary function is to protect electrical equipment and wiring on your boat from potential damage caused by excessive currents, whether from prolonged overloads or instantaneous short circuits.

This circuit breaker is rated for a nominal current of 30 amperes. This means it is designed to operate normally up to 30 A and will trip automatically above this value in case of overload, to protect the circuit.

Yes, the Blue Sea 187 series circuit breaker is a manually resettable circuit breaker. After tripping due to overload or short circuit, it can be reactivated by pressing its reset button once the cause of the issue has been resolved.

It provides protection against overloads and short circuits, essential for the safety of marine electrical installations. The 187 series is known for its ability to interrupt current quickly in case of a fault.

Blue Sea’s 187 series is known for its reliability, robustness, and ease of use. It provides essential protection without unnecessary complexity, helping to secure marine electrical installations with a quality product.

Yes, it is specifically designed for marine applications. Its materials and design are suited to withstand the demanding conditions of the nautical environment, such as humidity, vibrations, and temperature variations.

It acts as an essential safety device, functioning as an automatic switch that opens an electrical circuit to protect it and prevent damage to equipment or fire risks in case of electrical failure, such as an overload or short circuit.

Yes, Blue Sea 187-series circuit breakers are generally designed to be resistant to water spray, making them suitable for installation in exposed marine environments without compromising their operation.

With a 30-amp capacity, it can protect a wide range of onboard equipment, such as bilge pumps, lighting, navigation instruments, radios, or other secondary circuits requiring this level of protection.

This circuit breaker is designed for surface mounting. This means it is fixed directly onto a bulkhead, panel, or any other flat surface using screws, without requiring a cutout for flush mounting.

No, surface mounting is one of the simplest installation methods for a circuit breaker. It does not require specialized tools for precise cuts and allows for direct and accessible attachment, simplifying the process.

The Blue Sea 187 series circuit breaker can be mounted in any orientation (vertical, horizontal, or tilted) without affecting its performance, providing great flexibility for integration into various spaces aboard your vessel.

For 30-amp protection, it is essential to use appropriately sized cables (typically AWG 10 or 8 depending on length and local standards) and marine-grade quality to ensure circuit safety and efficiency.

It is essential to connect the circuit breaker in-line with the circuit to be protected, respecting polarity (if applicable) and using crimped and insulated ring terminals for secure and reliable connections to the circuit breaker terminals.

This circuit breaker is compatible with direct current (DC) electrical systems commonly used in marine applications, typically supporting voltages ranging from 12V to 48V DC, which covers the majority of boat installations.

Yes, its 30-amp design makes it versatile for use across a wide range of vessels, from small pleasure boats to larger sailboats and motorboats, wherever DC circuit protection is required.

Absolutely. As part of the Blue Sea Systems range, it is designed to integrate seamlessly with other brand products such as bus bars, distribution panels, or terminal blocks for a consistent and high-performance marine electrical installation.

Yes, it is an excellent alternative to 30-amp fuses. The main advantage is that it can be manually reset after tripping, eliminating the need to replace a blown fuse and providing added convenience on board.

It is ideal for protecting moderate-power circuits on board vessels, such as lighting circuits, pumps, fans, audio systems, USB chargers, or small electronic equipment, requiring 30-amp protection.
