Blue Sea Systems SMS 120V AC ELCI 50A Enclosure Kit

An ELCI (Equipment Leakage Circuit Interrupter) is a ground-fault circuit breaker designed to protect people from dangerous electric shocks. In the marine context, it is essential because it detects low earth leakage currents that may occur in the event of equipment or wiring failure, quickly cutting off the power supply to prevent the risk of electrocution. It is required by ABYC E-11.11.1 standard.

This ELCI panel is designed to operate with a 120V AC voltage and includes a 50A ELCI main circuit breaker.

Yes, this panel is specifically designed to comply with ABYC E-11.11.1 requirements. This standard mandates ground-fault protection within three meters of the shore power inlet.

The ELCI main circuit breaker of this panel has a breaking capacity of 3000A.

The panel is equipped with a red LED indicator to signal a polarity reversal and three green LEDs to indicate power-on, thus facilitating quick visual diagnosis of the system's status.

This panel integrates the main ELCI circuit breaker and features two additional empty circuit positions, allowing future installation of breakers for other circuits.

The main integrated ELCI circuit breaker is of the magnetic-hydraulic and trip-free type, providing reliable and robust protection.

This panel is a Surface Mount System (SMS) enclosure, which simplifies its installation on various surfaces.

The base of this housing is made of polycarbonate, a robust and durable material suitable for marine environments.

The primary function of the ELCI panel 120VAC 50A SMS ENCLOSURE (reference 3118-BSS) is to provide advanced protection for marine AC circuits by integrating a 50A ELCI main circuit breaker, ensuring safety against ground faults and compliance with ABYC standards.

The panel features a dedicated red LED that lights up to indicate polarity reversal, enabling rapid identification of this potential electrical issue.

Per ABYC E-11.11.1, this ELCI panel must be installed so that ground-fault protection is effective within three meters of the shore power inlet.

No, this panel is specifically designed and calibrated for 120V AC electrical systems. It must not be used with different voltages for safety and compliance reasons.

Yes, this panel is designed for AC marine circuit protection. Its polycarbonate base and robust design make it suitable for harsh marine environments, including salt exposure.

A "trip-free" circuit breaker cannot be held in the "ON" position manually if a fault condition (such as overload or earth fault) is present. It will trip automatically and remain tripped until the fault is corrected, ensuring maximum safety.

Given that this is an essential component of the marine electrical distribution system and is related to personal safety, the installation of this panel must be performed by a qualified marine electrician or a person with proven expertise in marine electrical systems to ensure compliance with standards and safety.

Yes, the panel includes a 50A ELCI main circuit breaker, making it suitable as the primary protection for the boat's AC power inlet, in compliance with marine safety requirements.

No, on a 120V AC single-phase system, the three green LEDs simply indicate that the panel is powered on, confirming that the supply is present. They do not represent distinct phases.

Yes, this product is specifically designed for protecting AC marine circuits and complies with safety standards applicable to this environment, such as ABYC E-11.11.1.

No, the panel is supplied with two blank circuit positions. The circuit breakers for these positions must be purchased separately according to the specific needs of the secondary circuits to be protected.
