Circuit breaker distribution box MARLANVIL 8-module IP55 model 92.08.SNK

The MARLANVIL Circuit breaker distribution box 8-module IP55 model 92.08.SNK is a surface-mounted enclosure designed to accommodate up to eight DIN-rail mounted modular devices such as miniature circuit breakers (MCBs), residual current devices (RCDs) or surge protectors. The IP55 rating provides protection against dust ingress and low-pressure water jets, making the enclosure suitable for indoor use and sheltered outdoor locations where enhanced protection is required. The box supports organized circuit distribution and straightforward installation on walls or panels.

Advantages

The enclosure offers a compact 8-module capacity that helps consolidate multiple protective devices in a single, accessible location while preserving a small footprint. Its IP55 ingress protection ensures reliable operation in environments exposed to dust or occasional water jets, reducing the risk of contamination or moisture affecting the installed devices. The surface-mounted design simplifies installation without the need for recessing, and the transparent or removable front cover allows visual inspection and easy access for maintenance.

Suitable for

• Small residential distribution panels where up to eight DIN-rail devices are needed
• Light commercial spaces requiring a compact, protected breaker enclosure
• Sheltered outdoor installations such as covered porches, garages or service rooms
• Temporary or permanent setups where surface mounting is preferred

When it may not be suitable

This distribution box is not intended for housing devices that exceed standard DIN-rail module widths or for installations requiring more than eight modules. It is also not suitable for fully exposed outdoor locations where immersion, high-pressure water jets, or corrosive atmospheres are present; in such cases, a higher ingress protection rating and corrosion-resistant materials should be chosen. The enclosure does not include the internal protective devices, so breakers, RCDs or other modules must be selected and installed separately.

Key specifications

• Mounting type: surface-mounted
• Capacity: 8 DIN-rail modular device positions
• Ingress protection: IP55 (protection against dust and low-pressure water jets)
• Suitable for DIN-rail modular devices: MCBs, RCDs, surge protectors and similar
• Material: durable enclosure material suitable for electrical installations (non-metallic)
• Access: front cover for visual inspection and maintenance access

How to use

Mount the distribution box on a stable, vertical surface using appropriate fixings for the substrate. Ensure the enclosure is positioned where it remains protected from direct weather exposure if installed outdoors. Install a suitable DIN-rail inside the enclosure if not pre-fitted, then mount the chosen modular devices (MCBs, RCDs, surge protectors) onto the rail according to their module widths and terminal clearances. Make all electrical connections following applicable wiring regulations, observing proper torque settings and ensuring neutral and earth terminals are correctly identified. Close and secure the front cover after verifying correct installation and test the circuit protection devices as required.

What to consider before purchase

• Confirm the total number of DIN-rail modules required and module widths to ensure they fit within 8 positions
• Check whether the IP55 rating matches the intended installation environment (sheltered outdoor vs fully exposed)
• Verify material and color requirements for compatibility with the installation area and any local regulations
• Plan for the necessary accessories such as DIN-rail, terminal blocks or glands if not included

Usage recommendations

Install and commission the distribution box in accordance with local electrical codes and standards. Use appropriate cable glands and seals for any external cable entries, and select modular protection devices with suitable ratings for the connected circuits. Periodically inspect the enclosure and seals to ensure ongoing protection against dust and moisture.
