Product Information

Full details

The OBO Bettermann 2000378 junction box is designed for electricians and installers needing a compact and reliable enclosure for electrical connections in domestic or commercial settings. Its primary benefit is providing secure, organized housing for wiring, ensuring safety and ease of maintenance. A key consideration is its IP55 rating, which offers protection against dust and low-pressure water jets, making it suitable for many environments but not for harsh, wet conditions without additional precautions. This plastic, halogen-free box features 8 inserts and accommodates cables from 7-14 mm in diameter, with 14 total inlets and a trimmable step membrane for flexible entry.

FAQs

What is the IP rating of this junction box?

The OBO Bettermann 2000378 junction box has an IP55 rating, meaning it is protected against dust ingress and against low-pressure water jets from any direction.

What size cables can be used with this box?

This junction box is designed to accommodate cables with a diameter ranging from 7 mm to 14 mm.

Is this junction box suitable for outdoor use?

While the IP55 rating offers protection against dust and water jets, prolonged direct exposure to harsh weather elements is not recommended without additional protective measures. It is best suited for sheltered outdoor or indoor applications.

Can I use this box in a hazardous area (Ex-zone)?

No, this junction box is explicitly stated as not suitable for Ex-zone gas or dust hazardous areas.

What material is the junction box made of?

The junction box is made of plastic and is halogen-free.

How is the cover attached?

The cover is attached via a snap-on mechanism for quick and easy installation and removal.

What are the dimensions of the box?

The junction box measures 100 mm in length, 100 mm in width, and 40 mm in depth.

Troubleshooting

Difficulty inserting cables

Ensure the cable diameter is within the 7-14 mm range. Use a sharp knife or specialized tool to carefully trim the step membrane to the appropriate size for your cable.

Cover won't snap securely

Check for any obstructions or debris on the box rim or cover. Ensure the internal wiring is not preventing the cover from seating correctly.

Water ingress despite IP55 rating

Verify that the step membrane is properly trimmed and sealed around all inserted cables. Ensure the cover is fully snapped shut. The IP55 rating is for protection against low-pressure jets, not submersion.

Setup, Compatibility & Care

Setup: This is a surface-mounted junction box. Choose a suitable mounting location and secure the box using appropriate screws (not included). Feed cables through the designated inlets, utilizing the trimmable step membrane for a snug fit. Connect your electrical wiring within the box. Finally, secure the cover by snapping it firmly into place.
