Who is OBO Bettermann and what does it make?
OBO Bettermann is a German manufacturer of systems for electrical installations, with a focus on surge protection, cable trays and cable management systems, fire protection and earthing systems. The company describes itself as one of the reference manufacturers of electrical installation systems for construction and industry. From the OBO Bettermann range we can quote, made to order, cable trays, surge arresters and fire protection systems for electrical contractors and industrial projects.
The technical range is organised in clear categories: cable management systems, fire protection systems, flush-mounted installation systems, connection systems, plus lightning and surge protection and solutions for underground installations. In surge protection, OBO Bettermann has ranges of arresters for electrical panels.
For the Romanian market, the range makes sense on industrial or commercial electrical installation projects where you need correctly sized cable trays, surge protection for sensitive equipment, or fire protection systems for cable routes through risk areas.
What do we supply from the OBO Bettermann range?
| Product | Description |
|---|---|
| Cable Trays and Cable Management Systems | Metal cable trays (solid and mesh type) for cable routes in industrial and commercial installations, in various widths and heights, with fixing and joining accessories. Typical application: distribution of power and data cables through production halls or office buildings. For a quotation, the customer must specify the tray width and height, the total route length and the type of installation environment. |
| Surge Protection Systems | Surge arresters for protecting electrical panels and sensitive equipment against impulses caused by lightning or network switching. Typical application: protection of photovoltaic installations, data centres or critical industrial equipment. The customer must specify the nominal voltage of the installation and the type of protection required (class I, II or combined). |
| Fire Protection Systems | Solutions for limiting the spread of fire along cable routes that cross fire-compartmented walls or floors, including sleeves and intumescent coatings. Typical application: cable penetrations through fire-resistant walls in industrial buildings or data centres. For a quotation, the required fire resistance (EI) and the diameter of the cable route are needed. |
| Earthing and Lightning Protection Systems | Components for earthing and lightning protection installations — conductors, electrodes and connection parts — sized for protecting buildings and equipment against atmospheric discharges. Typical application: lightning protection installations for industrial buildings or photovoltaic parks. The customer must send the installation diagram or the type of building to be protected. |

How do we supply OBO Bettermann in Romania?
For OBO Bettermann, availability and lead time are confirmed in the quotation — product information comes from the manufacturer's technical documentation, and we check availability individually for each order. We supply OBO Bettermann products made to order through EU supply channels, usually within 1–4 weeks of confirmation, without permanent availability from stock for all tray sizes or arrester types. For a fast quotation, send the exact product code or, if you do not have it, the type of system (tray, arrester, fire protection), the dimensions required and the route length. We do not publish prices without checking with the supplier.
We do not design complete lightning or surge protection schemes for buildings — we supply OBO Bettermann components according to a design already established by a licensed engineer.
Frequently asked questions about OBO Bettermann
What is the V50 arrester from OBO Bettermann?
V50 is a combined type 1+2 arrester from the OBO Bettermann range, used at the incomer of the electrical panel to limit both lightning currents and switching surges. It exists in single-, two- and three-pole versions with N and PE, at 280 V, plus a version dedicated to 600 V direct current photovoltaic installations. The choice of version depends on the earthing system and the network voltage.
What is the difference between the RKS-Magic 60 FS and FT cable trays?
The difference is the surface treatment of the steel: FT is hot-dip galvanised, with better corrosion resistance, while FS is another type of galvanised finish. Both belong to the RKS-Magic family, with a screw-free joining system. The right choice depends on the installation environment.
Do you supply OBO Bettermann cable trays and arresters in Romania?
Yes, we supply the OBO Bettermann ranges presented above made to order, and the wait until delivery is usually 1–4 weeks, depending on the model and the factory schedule. We do not keep these items on the shelf, and the information on codes and characteristics comes from the manufacturer's public materials; we confirm availability and lead time in the quotation. We recommend confirming the exact code before ordering.
How do I choose between V20 and V25-B+C for photovoltaic protection?
V20 is a type 2 arrester for general electrical panels, while V25-B+C combines type 1 and type 2 functions and is designed specifically for the incomer of photovoltaic installations, with a maximum open-circuit voltage (Voc) of up to 900 V direct current. If the solar panels are exposed to direct lightning risk, the V25-B+C version offers more complete protection than a simple type 2 arrester.
How do I request a OBO Bettermann quotation?
Send the OBO Bettermann code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
