Rafseglar 187 - Innsetning á spjald 135 A

The BLUE SEA Series 187 circuit breaker is a thermal protection device designed for marine electrical circuits. It protects equipment from damage caused by overcurrent and short circuits by automatically cutting off the electrical supply.

The main feature of this circuit breaker is its ability to handle a rated current of 135 amperes. It is designed for applications requiring robust protection on high-power lines, such as converters, bow thrusters, or large-capacity battery charging circuits.

Yes, the 187 series circuit breaker is an excellent alternative to fuses. It offers the advantage of being manually resettable after an overload, allowing quick restoration of service without needing to replace a fuse.

This BLUE SEA 187-series circuit breaker is designed to operate with electrical systems up to 48V DC.

Yes, this circuit breaker is protected against ignition per SAE J1171, making it safe for installation in engine compartments or other areas where flammable vapors may be present.

This circuit breaker is of the "manual reset, no trip latch" type. This means it must be manually reset after a trip and cannot be held closed if an overload condition persists.

The BLUE SEA 187 series circuit breaker complies with ABYC E-11, CE, and SAE J1171 standards, ensuring reliability and safety for marine applications.

This circuit breaker is designed for demanding marine environments. It is weather-resistant and flame-retardant, making it suitable for use in various locations aboard a vessel.

Thermal circuit breakers, such as BLUE SEA's 187 series, respond to overloads based on heat generated by current. They are robust and reliable for general circuit protection, providing an economical and resettable solution for most marine applications.

This circuit breaker is designed for panel mounting. It integrates directly into the ship's electrical panels or control consoles, requiring an appropriate cutout for installation.

The circuit breaker is fitted with large stud terminals, typically 5/16"-18, designed to accommodate thick cables suitable for the high currents it handles.

The exact cut-out dimensions for panel installation are available on the product’s technical diagram, usually provided with the circuit breaker or accessible on the product page. Refer to this diagram for precise installation.

Installation requires basic marine electrical tools, such as crimping pliers for cable terminals, wrenches for tightening stud terminals, and cutting tools to create the opening in the mounting panel. It is essential to use insulated tools for safety.

Yes, due to its flame-resistant rating (SAE J1171), this circuit breaker can be safely installed in an engine compartment or other areas where flammable vapors may be present, provided the environment meets the manufacturer's temperature and humidity specifications.

This circuit breaker is compatible with marine electrical systems operating on direct current (DC) up to 48V, which includes most 12V, 24V, and 48V DC installations found on boats.

Yes, it can be used to protect navigation equipment, provided the rated current of the equipment or circuit does not exceed 135 amperes and the system voltage is compatible (up to 48V DC).

Yes, this circuit breaker integrates seamlessly with other BLUE SEA power management products, such as busbars, battery switches, and distribution panels, enabling the construction of a consistent and secure electrical architecture.

Yes, with its 135 amp rated current, this circuit breaker is particularly suitable for protecting bow thrusters and other high-current-draw equipment, providing rapid tripping in case of overload.

Yes, like most products from the BLUE SEA Systems brand, this circuit breaker is covered by the manufacturer's standard warranty. For specific details regarding duration and conditions, please refer to the warranty information provided by BLUE SEA Systems or contact our customer service.
