Detailed description

Dissenyat per a la protecció de circuits elèctrics marins, el disjuntor BLUE SEA 2142-BSS de 50 A és una solució de tipus "medium duty" amb pols. Garanteix una protecció fiable contra sobreintensitats, essencial per a la seguretat dels equips i del sistema elèctric a bord.

Protecció i senzillesa d'ús

Aquest disjuntor integra un mecanisme de reinici per pol, que permet una reposició ràpida del circuit després d’un tall, sense necessitat de substituir un fusible. Aquesta funcionalitat el fa especialment adequat per a aplicacions on es requereix un accés fàcil i una resposta immediata. El model 2142-BSS es diferencia dels disjuntors amb palanca, que també poden actuar com a interruptors, en centrar-se únicament en la funció de protecció.

Posicionament tècnic

Amb una capacitat de 50 ampers i disseny "medium duty", aquest disjuntor BLUE SEA és ideal per a la protecció de càrregues específiques com ara bombes de sentina, petits convertidors o alguns grups d’il·luminació. Completa els sistemes de distribució de potència més complexos de la marca, oferint una protecció individualitzada on és més necessària, sense sobrecarregar un tauler principal. Les seves dimensions compactes i el seu gabarit de tall faciliten la seva integració en diversos taulers elèctrics o caixes de connexió.

« 50A BLUE SEA circuit breaker: targeted and resettable protection »

The BLUE SEA 2142-BSS circuit breaker is a relevant solution for targeted protection of secondary circuits on any type of vessel. With a 50A capacity, it is designed for intermediate loads such as high-power bilge pumps, certain DC/DC converters, or large LED lighting arrays.

The main advantage of this model lies in its push-button reset function, which simplifies managing tripped circuits. Unlike a lever-type circuit breaker that often combines protection and manual interruption functions, the 2142-BSS is a pure protection device. This is particularly useful for circuits not intended to be frequently switched but requiring reliable overcurrent protection.

Installation is straightforward thanks to its compact size and provided cutout templates, allowing discreet placement in secondary panels or junction boxes. It is an excellent option for complementing a main distribution system by adding dedicated protection for specific equipment without overloading the main panels. Note that it is not designed for protecting critical circuits requiring regular manual isolation or currents exceeding 50A without parallel connection.

Frequently Asked Questions

Need help? Contact us

What is the main function of the BLUE SEA 2142-BSS 50A circuit breaker?

The main function of this circuit breaker is to provide reliable protection against overcurrents in marine electrical circuits. It safeguards onboard equipment and the electrical system by cutting the circuit in case of overload, preventing damage.

How is the 2142-BSS circuit breaker reset after tripping?

This circuit breaker is of the 'reset only' type and features a push-button reset mechanism. After tripping due to an overcurrent, simply press the button to restore the circuit without needing to replace a fuse.

For which marine applications is this 50A circuit breaker best suited?

With its 50-amp capacity and medium-duty design, this circuit breaker is ideal for protecting specific loads on board. It is recommended for applications such as bilge pumps, small power inverters, certain lighting systems, or other equipment requiring individual overcurrent protection.

Is this circuit breaker designed for marine environments?

Yes, the BLUE SEA 2142-BSS circuit breaker is specifically designed for marine applications. Its construction and materials are selected to withstand harsh marine conditions such as humidity and temperature variations.

What types of terminals are used for electrical connection?

The BLUE SEA 2142-BSS circuit breaker uses #10-32 stud-type terminals for electrical connection. These studs allow secure cable connections using appropriate lugs.

Can this circuit breaker be used as an on/off switch?

No, this is a 'reset only' circuit breaker. It is designed to trip and protect a circuit in case of overcurrent, then be reset. It should not be used as a manual switch to turn equipment on or off, unlike lever-type circuit breakers that can serve this dual function.

How is the BLUE SEA 2142-BSS circuit breaker installed on an electrical panel?

The BLUE SEA 2142-BSS circuit breaker is designed for easy integration into an electrical panel or a marine junction box. To simplify installation, a cutting template is provided, allowing for precise opening to mount the push-button breaker flush. Its compact dimensions are an advantage for fitting into sometimes tight spaces. Once the opening is made, the circuit breaker is secured, and the electrical connections of the protected circuit are established.

What is the primary function of this 50A "Reset Only" circuit breaker?

The BLUE SEA 2142-BSS circuit breaker is a 50-amp "Reset Only" model, meaning its sole and primary function is to protect marine electrical circuits from overcurrent. Unlike lever-type circuit breakers that can also serve as switches to turn circuits on or off, this model focuses exclusively on detecting and interrupting excessive current.

With a 50A capacity, it is ideal for protecting specific loads such as:

Bilge pumpsSmall invertersCertain lighting circuitsWhen tripped due to overcurrent, resetting the circuit is done simply by pressing its button, eliminating the need to replace a fuse.
