Overview

The Vimar Arké 19411 RCBO range is a family of 1P+N residual current breakers with overcurrent protection for 120-230 V~ 50-60 Hz AC circuits. It brings short-circuit, overload, and residual-current protection together in one 2-module device, which helps when panel space is limited and you want the protection point kept at the branch circuit.

Across the range, current ratings run from 6 A to 16 A and residual-current sensitivity is 6 mA or 10 mA depending on version. The 6 A models are listed with 1500 A breaking capacity, while the 10 A and 16 A models are listed with 3000 A.

For a boat installation, this makes sense in a protected interior panel where an Arké modular layout is already in place and the circuit calls for an AC RCBO in this voltage range. It is a practical fit for refits, repairs, or panel updates where module width, finish, and trip rating all need to stay aligned with the rest of the switchgear.

Key features

• 1P+N RCBO layout combines overcurrent protection and residual-current protection in one device.
• Rated for 120-230 V~ 50-60 Hz AC circuits.
• 2-module Arké format for installations that need to match existing modular devices and trim.
• Range includes 6 A, 10 A, and 16 A current ratings with 6 mA or 10 mA residual-current thresholds depending on version.
• Available in Gray, White, and Metal finishes to match different Arké panel styles.
• Breaking capacity changes by rating: 1500 A on 6 A versions and 3000 A on 10 A and 16 A versions.

Variants

This range varies by finish, rated current, and residual-current threshold. Finish options include Gray, White, and Metal. Current rating is offered in 6 A, 10 A, and 16 A, while residual-current sensitivity is 10 mA on most versions and 6 mA on the 16 A variants marked 16.6.

The shared layout stays consistent across the range with 1P+N construction, 120-230 V~ 50-60 Hz supply, and a 2-module Arké format. Breaking capacity does not stay the same across every version, so that point should be matched to the chosen amperage as part of the selection.

Compatibility and fit

This device is for AC distribution circuits and is not a match for 12 V or 24 V DC systems. Before ordering for a boat, check the branch circuit voltage, the required current rating, the residual-current threshold, the available 2-module space, and the Arké finish already installed in the panel.

It suits boats where the electrical panel uses Arké modular devices and where a combined RCBO is preferred over separate protective components. It is less suitable when the vessel uses a different modular platform or when the circuit is part of a low-voltage DC distribution setup.

Installation and setup

On board, this breaker belongs in a protected electrical panel rather than an exposed helm, cockpit, or deck location. The main checks during installation are panel compatibility, conductor sizing for the selected amperage, space for the 2-module body, and a correct match between the breaker rating and the actual load on the circuit.

This range is a good match for yards and owners keeping an Arké panel consistent during a refit, or replacing a failed breaker without changing the surrounding layout. It also works well where the look of the panel matters and the finish needs to stay in line with the rest of the devices.
