Overview

The Vimar Eikon 20411 is a 1P+N RCBO that combines residual current protection with overcurrent protection for AC circuits on board. It supports 120-230 V AC at 50/60 Hz and installs as a 2-module built-in device with a 38 mm built-in depth, which suits compact distribution panels where space behind the faceplate matters.

On a boat, this type of RCBO is typically used on shore power or generator-fed branch circuits where you want one device to handle both overload and earth-leakage protection. It is rated IP40, so it belongs inside a panel that stays dry and is not exposed to washdowns or spray.

Key features

• 1P+N configuration with two poles total and one protected pole, with neutral switching for cleaner isolation on AC circuits
• 120-230 V AC, 50/60 Hz supply range for common shore power and generator distributions
• Trip curve C with options across C6, C10, and C16 rated current to match typical branch circuit loads
• Residual current sensitivity options (I?n) of 6 mA or 10 mA, depending on the configuration
• 2-module built-in format with 38 mm built-in depth for Eikon modular panel layouts
• IP40 protection level for enclosed electrical panels
• Leakage current type A and current limiting class 1
• Breaking capacity of 1500 A on C6 versions and 3000 A on C10 and C16 versions

Variants

This range is offered in multiple configurations that vary by front color (White, Grey, or Silver/Next) and by the protection settings listed for each part number.

Across the range, the format remains a 2-module, built-in 1P+N RCBO for 120-230 V AC at 50/60 Hz with IP40 protection and a 38 mm built-in depth. The combinations mainly differ by rated current (C6, C10, or C16) and residual current sensitivity (6 mA or 10 mA).

Compatibility and fit

These RCBOs are made for Vimar Eikon modular installations using a 2-module device position. Confirm you have two free module spaces on your AC panel and enough clearance behind the mounting surface for the 38 mm built-in depth plus wiring bend radius.

This is an AC protective device. It is not intended for 12 V or 24 V DC circuits, so it should be placed only on the AC side of your system.

Installation and setup

Mount the RCBO inside a panel or enclosure that keeps it away from spray, salt mist, and direct washdown. If the boat sees heavy vibration, route and support conductors so the terminals are not carrying cable weight.

Match the rated current to the conductor size and the expected load, and confirm the neutral switching arrangement matches how your AC distribution is wired. For safety and compliance, installation and testing should be handled by a qualified marine electrician following the applicable standards for your vessel and cruising area.

Use cases on board

This style of RCBO is a good match for refits where an Eikon-based AC panel is used for shore power branch circuits like outlets, water heaters, battery chargers, or galley appliances, and you want a single device per circuit rather than separate RCD and breaker hardware.
