Jistič série 187 – montáž na panel 60 A

The BLUE SEA 187 series circuit breaker is a thermal protection device designed specifically for marine electrical circuits. It can detect and automatically interrupt the current flow in case of overload or short circuit, thereby protecting the boat's equipment, cables, and electrical system.

This circuit breaker model, the BLUE SEA 187 series (reference 7040-BSS), has a rated capacity of 60 amperes (60 A). This means it is designed to protect circuits where the normal current does not exceed this value.

Yes, this circuit breaker is resettable. Unlike fuses, which must be replaced after tripping, the 187 series circuit breaker can be manually reset once the fault has been corrected, offering convenience and reducing consumables.

A circuit breaker plays a crucial role in protecting marine electrical systems. Its main functions are:

Overload protection: It cuts the circuit if the current exceeds the rated value (here 60 A) for an extended period, preventing cable and equipment overheating. Short-circuit protection: It reacts instantly to interrupt excessive current caused by a short circuit, thus preventing serious damage and fire risks. Safety: It protects people and equipment by quickly isolating electrical faults.

This 60 amp circuit breaker is suitable for protecting circuits requiring medium to high power protection in a marine environment. Typical applications include:

High-power navigation equipment.Bilge or livewell pumps.Power battery charging systems.Inverters or power converters.Other high-power electrical devices on board.

The BLUE SEA 187 series circuit breaker is generally designed for systems up to 48V DC. It is therefore perfectly suited for common marine installations at 12V DC or 24V DC.

This circuit breaker can operate reliably across a wide temperature range, typically from -40°C to +85°C, making it suitable for various marine weather conditions encountered at sea.

The circuit breaker housing is made of UV-stabilized thermoplastic. This material ensures excellent durability and resistance to marine elements, including prolonged exposure to sunlight and saltwater.

Yes, the 187 series circuit breaker model 7040-BSS is specifically designed for panel mounting. This type of mounting allows for a clean and accessible installation, making it easier to integrate into dashboard or distribution electrical panels.

Yes, for a safe and efficient installation, several wiring considerations are important:

Cable cross-section: Use cables with an appropriate cross-section to handle a continuous current of 60 amperes, in accordance with ABYC standards or equivalent, to prevent overheating. Connections: Ensure all connections to the circuit breaker terminals are clean, secure, and tightly fastened to minimize resistance and prevent hot spots. Protection: Protect cables from abrasion and physical damage. Polarity: Respect polarity when connecting if the circuit breaker is polarity-sensitive (though most DC circuit breakers are not for their basic function, it is a good general practice).

Yes, this 60 A circuit breaker is fully compatible with 12 V DC systems, as well as other common DC voltages up to 48 V DC. It is designed to operate efficiently in most boat electrical installations.

No, the BLUE SEA 187 series circuit breaker is specifically designed for direct current (DC) systems. It must not be used with alternating current (AC) systems, as its tripping and breaking characteristics are not suitable for this type of current.

Yes, this circuit breaker integrates perfectly with an electrical system using other BLUE SEA Systems products. The brand designs its equipment to work in harmony, providing a complete and reliable solution for the management and protection of marine circuits.

Yes, it can replace a 60-ampere fuse in a DC circuit, with the significant advantage of being resettable. It is important to verify that the voltage specifications and interrupting capacity of the circuit breaker match or exceed the requirements of the circuit previously protected by the fuse.

This circuit breaker is designed to meet stringent marine safety standards. It is specifically ignition-protected in accordance with SAE J1171, making it safe for use in engine compartments where flammable vapors may be present. It is also typically CE-certified, attesting to its compliance with European safety requirements.
