KARWASZ RU-3 Z/O/E Universal Meter Cabinet for 1 Three-Phase Meter, 12 Modules, IP30

The KARWASZ RU-3 Z/O/E is a professional-grade universal meter cabinet engineered to provide a secure and organized housing solution for electrical metering and distribution equipment. This versatile enclosure is designed to accommodate one three-phase electricity meter while offering additional space for up to 12 modular devices, such as circuit breakers or residual current devices. Its robust construction ensures reliable performance in residential and commercial indoor electrical systems.

Advantages

The primary benefit of this cabinet is its dual-mounting capability, allowing for both surface and flush installation depending on the specific requirements of the building infrastructure. The design prioritizes ease of access for maintenance while maintaining a clean and professional appearance. By integrating both the meter and modular protection components into a single unit, it significantly simplifies the electrical installation process and optimizes space within utility rooms or distribution areas.

Suitable for

• Residential electrical metering installations
• Commercial building distribution boards
• Housing three-phase electricity meters
• Organizing modular circuit protection devices

When it may not be suitable

This cabinet is rated IP30, meaning it is not protected against water ingress or high levels of dust. Therefore, it is not suitable for outdoor use or installation in damp, humid, or harsh industrial environments where moisture or debris could compromise the internal components.

Key specifications

• Capacity: 1 three-phase meter and 12 modular spaces
• Mounting type: Universal (surface or flush)
• Protection rating: IP30
• Application: Indoor use
• Depth: 115 mm

How to use

The cabinet should be installed by a qualified electrician in accordance with local electrical codes. For flush mounting, prepare a wall recess of the appropriate size, insert the cabinet, and secure it firmly. For surface mounting, fix the enclosure directly to a flat, stable wall surface using the provided mounting points. Once secured, mount the three-phase meter onto the designated base and install the modular devices onto the DIN rail. Ensure all wiring is correctly routed and terminated before closing the front cover.

What to consider before purchase

• Verify the dimensions of your specific three-phase meter to ensure compatibility.
• Confirm that the installation environment is dry and protected from dust.
• Check if the 12-module capacity is sufficient for your planned circuit protection requirements.

Usage recommendations

Always ensure the power supply is disconnected before performing any installation or maintenance work inside the cabinet. Regularly inspect the enclosure for any signs of physical damage or loose connections to maintain safe operation.
