Blue Sea Systems SMS 240 V AC ELCI 50 A Enclosure

An ELCI (Equipment Leakage Circuit Interrupter) is a ground fault circuit breaker. Its primary role is to protect people from electric shocks by detecting ground fault currents and quickly cutting off the electrical supply. In this panel, it provides essential protection for 240 V AC marine installations.

This panel is designed to operate at a nominal voltage of 240 V AC.

The panel integrates a main ELCI circuit breaker with a 50 A rating.

Yes, this panel is specifically designed for use with isolation transformers.

The housing is made with a base of glass-reinforced polycarbonate. The cover screws and hardware are made of 10-32 stainless steel.

The overall external dimensions of the enclosure are 192 mm x 188 mm x 120 mm (length x width x depth).

The weight of this panel is 1.81 kg.

Yes, the panel’s design—with its base in reinforced polycarbonate glass and stainless-steel hardware—ensures durability and robust resistance to marine environments.

This panel can operate within a temperature range from -35 °C to 66 °C.

Yes, this panel includes a built-in 50 A ELCI main circuit breaker.

The seamless PUR (polyurethane) gasket, formed in place and oversized, ensures enhanced sealing of the housing, protecting internal components from moisture and marine elements.

By integrating a 50 A ELCI main circuit breaker, this panel provides protection against earth leakage currents, significantly reducing the risk of electric shocks for people on board, in compliance with marine safety standards.

The abbreviation "SMS" stands for Surface Mount System, indicating that the panel is designed for surface mounting.

Yes, this panel is designed to meet ABYC E-11 requirements, particularly when installed within 3 meters of a shore power inlet. Compliance with E-11.11.1 has been mandatory since January 1, 2013.

For optimal compliance with ABYC E-11, this panel must be installed within 3 meters (approximately 10 feet) of the shore power inlet.

Yes, the cover screws and hardware are made from 10-32 stainless steel, providing excellent corrosion resistance in marine environments.

This panel is designed for 240 V AC single-phase installations, typical of shore power systems for recreational vessels.

No, this panel is specifically designed for use with isolation transformers to ensure protection and compliance with standards.

Although the housing is rugged and waterproof, electrical distribution panels and ELCIs are typically installed in protected areas inside the boat, in accordance with marine installation best practices, while respecting the 3-meter distance from the dock inlet.

This panel is designed for 240 V AC marine installations requiring 50 A ELCI protection, particularly when used with an isolation transformer. Its suitability depends on the vessel’s specific electrical architecture and power requirements rather than overall size.
