187 seeria katkestaja – 135 A, pinnasele monteeritav

This is a thermal circuit breaker designed for electrical protection of marine circuits. It can interrupt the current flow in case of overload or short circuit, protecting equipment and wiring aboard.

Its main function is to protect the vessel's electrical installation by automatically cutting off the circuit when the current intensity exceeds 135 amperes, whether due to an overload or a short circuit.

This circuit breaker has a rated capacity of 135 amperes, meaning it is designed to operate normally up to this current and trip beyond it.

Yes, it is specifically designed for marine environments. The Blue Sea Systems 187 series is known for its robustness and reliability in nautical applications.

It is particularly suited for protecting high-current power circuits, such as main power lines for equipment like bow thrusters, windlasses, or high-capacity inverters.

This is a thermal circuit breaker. It reacts to the internal temperature rise caused by excess current, triggering a trip to protect the circuit.

Yes, this circuit breaker is manually resettable. Once the cause of the overload or short circuit has been identified and resolved, it can be reactivated by pressing its reset button.

This circuit breaker is manufactured by Blue Sea Systems, a leading and recognized brand for high-quality electrical solutions designed for marine applications.

Yes, its design is robust and suited to marine environments, allowing it to operate reliably despite the humidity, vibrations, and temperature variations typical aboard a vessel.

A circuit breaker, like this model, can be manually reset after tripping, making it reusable. A fuse, on the other hand, must be replaced once it has melted to interrupt the circuit in case of overcurrent.

This circuit breaker is designed for direct current (DC) systems commonly found in marine applications, particularly for powering onboard equipment.

No, this thermal circuit breaker is specifically designed to protect against overcurrents (overloads and short circuits). Surge protection requires dedicated devices such as surge protectors.

This circuit breaker is designed for surface mounting. This means it is fixed directly to a wall or panel, making positioning and attachment easier in various compartments of the vessel.

Installing marine electrical components should ideally be carried out by someone with knowledge of marine electrical systems to ensure the safety of the installation and its compliance with standards.

Surface mounting typically involves using screws to secure the circuit breaker body to the chosen wall or panel. Mounting points are built into its design for easy installation.

It is recommended to mount it in a dry and accessible location to facilitate rearming and maintenance. Although it is designed for the marine environment, protecting it from direct prolonged water splashes will extend its lifespan.

It is designed to be connected with power cables rated for 135 amperes. It is critical to comply with cable cross-section and crimping standards for marine applications to ensure a secure and efficient connection.

For a secure and reliable connection, it is strongly recommended to use terminals or connectors suited to the cable cross-section and the 135 A current rating. These terminals must be properly crimped and securely fastened to the circuit breaker terminals.

It is compatible with marine electrical architectures requiring overcurrent protection for high-power circuits. This includes systems powering equipment such as bow thrusters, windlasses, or inverters.

Blue Sea Systems 187 series circuit breakers are designed for marine DC (direct current) systems. While the maximum voltage is not specified here, they are commonly used in 12V, 24V and 48V DC systems.
