Wyłącznik serii 187 – montaż na panelu 100 A

The Blue Sea Systems 187 series circuit breaker is an electrical protection device designed for marine environments. It protects high-consumption circuits from overcurrents by automatically interrupting the current. Unlike fuses, it can be manually reset after tripping, providing a reusable and practical solution.

This specific circuit breaker has a rated current of 100 Amperes (100 A), making it suitable for protecting circuits requiring high current capacity.

This 187 series circuit breaker is designed to operate with electrical systems up to 48 volts DC.

Yes, one of the main advantages of this circuit breaker is that it can be manually reset. After tripping due to an overload or short circuit, you simply need to resolve the issue and reset the breaker to restore power, without having to replace it like a fuse.

This circuit breaker is designed for panel mounting. This means it is recessed into an electrical panel or a flat surface, providing direct operator access and a clean integration into the installation.

This 100 A circuit breaker is suitable for protecting high-consumption critical circuits on board vessels, such as:

Inverter systemsBow thrustersWindlassesMain distribution circuits

Yes, Blue Sea Systems’ 187 series circuit breaker is generally designed to be ignition-protected in accordance with marine standards such as SAE J1171 and ISO 8846. This feature is essential for safety in engine compartments where flammable vapors may be present.

This circuit breaker uses 5/16"-18 stainless steel studs for cable connections. These robust terminals ensure a reliable and secure electrical connection.

The main difference lies in their operation after an overcurrent event. A fuse is a single-use device that must be replaced after melting to interrupt the circuit. A circuit breaker, such as the 187 series model, can be manually reset after tripping, making it reusable and more practical for maintenance.

Yes, given its maximum voltage of 48V DC, this circuit breaker is fully compatible with common marine 12V and 24V DC electrical systems, providing effective protection for these installations.

For a 100 A circuit breaker, it is crucial to use cables of the appropriate gauge to handle such current without overheating. Connections must be clean, tight, and protected against corrosion, using the provided 5/16"-18 studs. It is recommended to follow ABYC wiring standards or local regulations in force.

Blue Sea Systems’ 187 series is recognized for its robustness and reliability in marine environments. Its advantages include:

High interrupting rating (AIC)Ignition protectionPractical manual reset mechanismCompact panel-mount designCompliance with maritime standards

Blue Sea Systems 187 series marine circuit breakers are designed to operate within a wide temperature range, typically from -40°C to +85°C, making them suitable for the varied conditions encountered at sea.

No, this circuit breaker is a complete protection device on its own. It performs the function of a fuse by interrupting the current in case of overload or short circuit, with the added advantage of being resettable. Therefore, it is not necessary to add a fuse holder in series for the same circuit protected by this circuit breaker.

Yes, Blue Sea Systems circuit breakers, including the 187 series, are specifically designed for marine environments. They are built with corrosion-resistant materials and saltwater spray protection, ensuring long service life and reliable performance aboard.
