Disjuntor sèrie 187 - Muntatge panell 150 A

The primary function of this circuit breaker is to protect marine electrical circuits from overcurrents and short circuits. It interrupts the current flow when the load exceeds the 150 ampere capacity, preventing damage to equipment and cables.

This Blue Sea 187 series circuit breaker is rated for a nominal capacity of 150 amperes. This means it can handle a continuous current up to 150 A before tripping in case of overload.

Yes, this circuit breaker is manually resettable. Unlike a fuse that must be replaced after tripping, the 187 series breaker can be reset by pressing a button once the cause of the overload or short circuit has been resolved.

The main difference is that a circuit breaker is resettable, whereas a fuse is single-use and must be replaced after tripping. Circuit breakers offer greater convenience and better flexibility for troubleshooting and restoring operation in a marine electrical system.

This circuit breaker is specifically designed for 12 V and 24 V marine electrical systems. Its robust design and ignition protection make it ideal for the marine environment.

Yes, the Blue Sea 187 Series circuit breaker is ignition protected per SAE J1171, making it safe for use in gasoline engine compartments where flammable vapors may be present.

This circuit breaker is designed to support a maximum voltage of 48 V DC. It is therefore compatible with 12 V, 24 V, 36 V and 48 V DC marine systems.

This circuit breaker is designed for panel mounting. It requires a cutout in the control panel or electrical panel for installation, allowing direct access and a clean integration.

The exact cutout dimensions required for panel mounting are provided in the detailed technical drawing of the product. It is recommended to refer to this document for precise measurements before installation.

This circuit breaker is equipped with M8 (5/16"-18) threaded stud terminals for cable connections. These robust studs ensure secure connections for high-current cables.

The Blue Sea 187 series circuit breaker can be installed in any orientation, providing great flexibility for integration into various electrical panels or control panels aboard vessels.

The 187 series provides reliable protection against overcurrent and short circuits, is resettable, resistant to marine environments (ignition-protected), and designed for high-power applications. Its robustness and ease of integration make it a preferred choice for electrical safety aboard.

This circuit breaker is ideal for protecting main circuits or high-consumption branch circuits such as inverter power lines, bow thrusters, windlasses, or battery charging systems.

Yes, this circuit breaker is 'trip-free' designed. This means it cannot be manually held closed in the event of an overload or persistent short circuit, thus ensuring the circuit remains protected even if the reset button is held down.

The housing for this circuit breaker is made of UV-stabilized thermoplastic. This material provides excellent durability and resistance to marine elements, including exposure to sunlight and salt water.

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

To connect the wiring to the M8 terminals, standard tools such as a socket wrench or an appropriately sized open-end wrench (typically 13 mm or 1/2 inch) will be needed to tighten the nuts on the connection studs.

Yes, the 7048-BSS circuit breaker is perfectly suited for protecting battery charging systems, including power lines for chargers or alternators, thanks to its 150 A capacity and robustness.
