Srovės saugiklis serija 187 – 100 A montavimas skydelyje

The Blue Sea Systems Series 187 circuit breaker is an electrical protection device designed for marine environments. It protects high-current circuits from overcurrent by automatically interrupting the power. 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 (direct current).

Yes, one of the major advantages of this circuit breaker is that it is manually resettable. After a trip caused by an overload or short circuit, simply resolve the issue and reset the circuit breaker to restore power, without needing 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 access for the operator and a clean integration into the installation.

This 100 A circuit breaker is ideal for protecting high-consumption critical circuits aboard vessels, such as:

Inverter systemsBow thrustersWindlassesMain distribution circuits

Yes, the 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 how they operate 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 convenient for maintenance.

Yes, with a maximum DC voltage rating of 48V, 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 critical 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 applicable local regulations.

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

High interrupting rating (AIC)Protection against ignitionA convenient manual reset mechanismCompact panel-mount designCompliance with marine standards

Blue Sea Systems marine circuit breakers in the 187 series are designed to operate across 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 benefit of being resettable. It is therefore 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 the marine environment. They are made with materials resistant to corrosion and saltwater spray, ensuring long service life and reliable performance on board.
