Series 187 Circuit Breaker - Panel Mount 60 A

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

This circuit breaker model, the BLUE SEA 187 series (part number 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, providing convenience and reducing consumables.

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

Overload protection: It cuts off 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 severe damage and fire hazards.Safety: It protects people and equipment by quickly isolating electrical faults.

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

High-power navigation equipment.Capacity or livewell pumps.High-capacity battery charging systems.Inverters or power converters.Other high-power electrical devices aboard.

The BLUE SEA 187 series circuit breaker is typically 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.

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

Yes, the 7040-BSS series 187 circuit breaker is specifically designed for panel mounting. This type of mounting allows for 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 gauge: Use appropriately sized cables to handle continuous 60 amp current, in accordance with ABYC or equivalent standards, 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: Observe polarity when connecting if the circuit breaker is polarity-sensitive (though most DC circuit breakers are not for their basic function, it is good general practice).

Yes, this 60 A circuit breaker is fully compatible with 12V DC systems, as well as other common DC voltages up to 48V 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 suited for this type of current.

Yes, this circuit breaker integrates seamlessly into 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-amp fuse in a DC circuit, with the significant advantage of being resettable. It is important to verify that the voltage rating and interrupting capacity of the circuit breaker meet or exceed the requirements of the circuit previously protected by the fuse.

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