Blue Sea 3128 - SMS Panel Enclosure w/ELCI (30A) & 3 Branch (15A) - 120V AC

The Blue Sea 3128 SMS Panel Enclosure with ELCI (30A) and 3 Branch (15A) circuits is an essential marine-grade electrical control hub designed for serious anglers and boaters. This enclosure allows for safe management of 120V AC power, whether at the dock or aboard larger vessels. Proper shore power management is crucial for protecting onboard electronics and maintaining battery health during extended stays at the marina.

This compact enclosure features built-in ELCI (Equipment Leakage Circuit Interrupter) protection on the main 30-amp circuit, along with three independent 15-amp branch circuits. This setup is ideal for distributing power to various onboard systems, such as galley equipment and cabin lights. The ELCI function acts as a specialized ground-fault detector, ensuring safety by monitoring for unintended current leakage and disconnecting power in milliseconds.

The Blue Sea 3128 is particularly beneficial for trawlers and mid-sized cruisers where space is limited, as it measures just 9 x 6 x 9 inches and weighs 3.3 pounds. With the ability to isolate and protect individual loads, this enclosure ensures that if one circuit trips, the entire electrical system remains operational. Compliance with ABYC standards further enhances its reliability and safety for marine applications.
