NEMA L5 Standard - Recognized worldwide

What is NEMA L5? NEMA (National Electrical Manufacturers Association) is a globally recognized standard for electrical connectors. The L5 standard defines the specifications for 230V/32A shore power connections and guarantees compatibility.

International compatibility: NEMA L5 sockets are compatible with all standard shore power cables. No matter where you dock, with NEMA L5 you have the right connection.

Safe standard: The NEMA L5 standard defines not only mechanical compatibility, but also safety requirements such as contact distances, insulation and load capacity.

IP56 protection class - Maximum protection

What does IP56 mean? The IP56 protection rating guarantees complete protection against dust (number 5) and protection against powerful water jets from all directions (number 6). Ideal for marine use.

Dustproof: The socket is completely protected against the ingress of dust. Its functionality is maintained even in dusty ports or during sandstorms.

Water jet resistant: Strong water jets from any direction cannot harm the socket. Even in rain, spray, or when cleaning the deck, everything remains dry and safe.

Screw cap: The stainless steel screw cap offers additional protection when not in use. Simply screw it on, and the socket is optimally protected against the elements.

Stainless steel A4 - Maximum corrosion resistance

High-quality A4 stainless steel: The bezel and screw cap are made of A4 stainless steel (also known as V4A or 1.4401/1.4404). This is the highest quality marine-grade stainless steel with maximum corrosion resistance.

Saltwater resistant: A4 stainless steel is specifically designed for use in saltwater environments. It resists corrosion from saltwater, salt spray, and aggressive marine atmospheres.

Durable: Even after years of intensive use in a marine environment, A4 stainless steel retains its properties. No rusting, no fading, no corrosion.

Professional look: The polished stainless steel surface offers a sophisticated, professional appearance and blends harmoniously into high-quality boat superstructures.

230V / 32A - High-performance power supply

230 Volt Voltage: The socket supplies 230V AC voltage – the European standard for shore power. Perfect for all onboard devices that require 230V.

32 Amp current: With a 32A current rating, you can also operate power-hungry devices. This corresponds to a power output of up to 7.4 kW – sufficient for air conditioning, heating, battery charger and all other onboard consumers simultaneously.

Safe sizing: The 32A rating offers sufficient reserve and prevents overload. Even with all onboard consumers in full use, you remain within safe limits.

With or without a case - your choice

Version without housing (UM6371ELX): This version is supplied without a separate housing. You install the socket directly into your boat's superstructure – ideal for professional installations in GRP superstructures, wooden paneling, or stainless steel panels. Space-saving and flexible.

Version with enclosure (UM6371EL-BX): This version comes with a separate enclosure. The enclosure provides additional protection and simplifies installation, especially when a suitable mounting situation is not available. Ideal for retrofits.

Both versions IP56: Whether with or without housing - both versions offer IP56 protection and the same high-quality stainless steel.

Shore power connection - Reliable power supply at the berth

What is a shore power connection? A shore power connection allows you to supply your boat with electricity from its berth. You connect a cable from the harbor socket to your onboard socket and have 230V shore power available.

Advantages of shore power: With shore power, you can operate all onboard appliances without draining the battery or running the generator. Air conditioning, heating, battery charger, refrigerator – everything runs on shore power.

Battery protection: You can charge your batteries via the shore power connection and simultaneously operate all appliances. The batteries are protected and always fully charged.

Quieter berth: With shore power, you don't need to run a generator. This is quieter, more environmentally friendly, and more pleasant for you and your neighbors in the harbor.

Easy installation - Professional installation

Installation in boat superstructures: The socket is installed in your boat superstructure. Cut a suitable opening, insert the socket and screw it in from the back.

Electrical connection: Connect the socket to your onboard electrical system. Ensure correct wiring (live, neutral, ground) and adequate protection (32A fuse).

Professional installation recommended: You should hire a qualified professional for the installation. Electrical installations on boats are subject to special safety requirements.
