Rafmagnsrofi 285 - Yfirborðsmontun 100 A

This is a thermal circuit breaker designed specifically for protecting electrical circuits in marine environments. It safeguards the system against overloads and short circuits by quickly cutting off power.

This circuit breaker has a rated current of 100 amperes (A), making it suitable for high-current circuits.

In a marine installation, a circuit breaker is an essential safety component. It protects the wiring and electrical equipment on board from damage caused by excessive currents (overloads) or short circuits by interrupting the circuit in case of a fault.

Yes, Blue Sea Systems 285-series circuit breakers are generally designed to be weather-resistant and suitable for marine environments. They are often IP67 certified, meaning they are protected against temporary immersion and dust.

This circuit breaker is designed for direct current (DC) systems and typically supports a maximum voltage of 48V DC.

This circuit breaker has a manual reset. After tripping due to overload or short circuit, it must be manually reset by operating its lever to restore the circuit.

Yes, Blue Sea Systems 285 series circuit breakers are 'trip-free' designed. This means they trip even if the lever is held in the 'ON' position, ensuring continuous protection against overloads and preventing forced reactivation of the circuit until the issue is resolved.

Blue Sea Systems circuit breakers are manufactured with robust, corrosion-resistant materials, such as thermoset plastics and treated metal components, to ensure maximum durability in marine environments.

This model is specifically designed for surface mounting. It is directly fixed to a wall or panel using screws, providing a flexible solution for installations where space or configuration does not allow for flush mounting.

Installing this circuit breaker typically requires basic tools such as:

A screwdriver (flathead or Phillips, depending on the mounting screws)A drill for mounting holesCrimping tools for cable terminalsA wrench to tighten the terminal nuts

You can install this circuit breaker on any flat, accessible surface, such as an electrical panel, an engine compartment, or a console. It is important to choose a location where it will be protected from excessive physical damage and easily accessible for maintenance or reset.

Yes, it is crucial to use cables of the appropriate cross-section to handle 100 A to prevent overheating. Connections to the terminals must be solid, secure, and insulated to ensure good electrical conductivity and system safety.

Cables are connected to the threaded studs of the circuit breaker using appropriate terminals (usually ring terminals). These terminals must be properly crimped onto the cables and then securely fastened to the studs with washers and nuts to ensure excellent electrical conductivity and withstand marine vibrations.

Yes, with a maximum voltage rating of 48V DC, this circuit breaker is fully compatible with common marine electrical systems of 12V DC and 24V DC.

Yes, this 100 A circuit breaker is suitable for protecting battery charging circuits, inverters, windlasses, bow thrusters, or other high-current equipment, provided the maximum current of the circuit to be protected does not exceed 100 A.

No, this 285-series circuit breaker is specifically designed and certified for direct current (DC) systems only. It must not be used for alternating current (AC) applications.

Although it can technically interrupt a circuit, its primary function is overcurrent protection. For a main switch, a battery switch or disconnect switch is often more suitable. However, it can be used in combination with other switching devices.

Yes, Blue Sea Systems products, including the 285 series, are designed and manufactured to meet relevant electrical safety standards for marine applications, ensuring reliable and compliant circuit protection.

Blue Sea Systems circuit breakers are renowned for their robustness and reliability in demanding marine environments. Proper installation, adherence to technical specifications, and the use of suitable cables are essential to ensure its proper operation and longevity.

Yes, this circuit breaker is specifically designed to withstand harsh marine environment conditions, including humidity, salt spray, vibrations, and temperature variations, thanks to the use of corrosion-resistant materials and robust construction.
