Disjunctor serie 187 - Montare panou 200 A

The BLUE SEA 187 series 200 A circuit breaker is designed to protect high-current marine electrical circuits. It provides essential interruption and protection against thermal overloads and magnetic short circuits for high-power equipment such as inverters, bow thrusters, or high-power charging systems.

This circuit breaker has a rated current of 200 A, making it suitable for protecting circuits requiring robust high-current management.

Yes, the BLUE SEA 187 series circuit breaker is ignition-protected, making it safe for installation in engine compartments of gasoline-powered boats, in compliance with SAE J1171.

This circuit breaker is manual type with a "Trip-Free" design, meaning it cannot be held closed manually if an overload or short-circuit condition persists. It must be manually reset after resolving the issue.

This circuit breaker provides dual protection: thermal protection against prolonged overloads and magnetic protection against instantaneous short circuits, ensuring the integrity of the installation and the safety of connected equipment.

The BLUE SEA 187 series circuit breaker is designed to operate with DC systems up to a maximum of 48V DC.

This circuit breaker is designed to operate across a wide temperature range, from -40°C to +85°C, making it suitable for various marine environments and extreme conditions.

This circuit breaker is designed for panel mounting, meaning it integrates directly into electrical panels or control panels via a specific cutout.

For installation, you will generally need basic tools such as a hole saw or jigsaw for cutting the panel, a screwdriver to secure the circuit breaker and tighten terminals, and crimping pliers for cables. It is recommended to follow the manufacturer's instructions.

The circuit breaker requires a specific cutout in the panel. The exact dimensions are usually provided in the cutout template or the product’s installation manual. It is essential to refer to these documents for correct and safe installation.

Yes, due to its ignition protection (compliant with SAE J1171 standard), this circuit breaker can be safely installed in engine compartments of gasoline-powered motorboats, where the presence of flammable vapors is possible.

Yes, for a 200 A circuit breaker, it is crucial to use cables with the appropriate cross-section to handle such current without overheating. It is recommended to consult ABYC standards or other applicable maritime standards for cable sizing to ensure the safety and efficiency of the installation.

This circuit breaker is compatible with a wide range of high-power marine equipment, such as inverters, bow thrusters, windlasses, high-power charging systems, and main DC circuits requiring 200 A protection.

Yes, this circuit breaker is fully compatible with 12V DC marine electrical systems, providing essential protection for high-current circuits in this voltage configuration.

Yes, this circuit breaker is also compatible with 24V DC and 48V DC systems, with an interrupting capacity suited to these voltages. It is important to respect the maximum voltage of 48V DC.

No, the BLUE SEA 187 series circuit breaker is specifically designed for DC (direct current) applications and must not be used in AC systems. Using it in an AC system could cause malfunction or safety hazards.

Yes, this circuit breaker can replace a 200 A fuse in many applications, offering the advantage of manual reset after tripping without requiring replacement of a fuse element. It also provides superior thermal and magnetic protection.

Yes, this 200 A circuit breaker is suitable for protecting circuits linked to lithium batteries, provided the continuous current and current peaks of the system remain within the breaker’s operating limits and the maximum voltage of 48 V DC is not exceeded. It is essential to size the circuit breaker correctly in relation to the battery BMS and the loads.
