Reyrolle has been synonymous with electrical protection devices in the sectors of subtransmission, distribution, and industrial applications for decades. Historically, Reyrolle relays were sold mainly in traditional markets but are now sold worldwide as part of the Siemens protection network.

Since its foundation, Reyrolle has been an innovation driver in product development – based on a strong focus on market, customer and technology. Worldwide established brand names such as “Solkor” and “Argus” demonstrate this. But there is more: A wide range of Reyrolle products has determined technological firsts in the market.

The comprehensive range of Reyrolle products provides the total protection requirements of distribution markets – ranging from overcurrent protection via transformer protection and voltage control to a full spectrum of auxiliary and trip relays. The port- folio includes many famous products such as “Argus”, “Duobias”, “Solkor”, “Rho”, etc.

To serve specific needs in industrial applications, a range of proven products such as “Argus overcurrent”, “Solkor line differ- ential” and “Rho motor protection devices” is offered.

Through successive generations, Reyrolle numerical products have been developed to increase value to system operators. This increase in value is the result of consistent development:

• Ease-of-use as a principle – our withdrawable product solu- tions allow flexible, easy operation through high user friendli- ness.

• One size fits all – the 4U housing height and the latest gener- ation of numerical products features 1 A/5 A CT Input, and some models are provided with universal DC power supplies.

• Learn once, know all – the new product generation provides a similar look and feel as earlier products. If Reyrolle numerical devices have been previously used, there is a high consistency in both programming and interrogation.

• With Reydisp Evolution, a comprehensive software support toolkit for relay setting, fault interrogation and general system information is provided. It is backward-compatible with all previous Reyrolle numerical devices.

• IEC 61850 communication interface option.

The Reyrolle product range offers a wide variety of protection devices. The table above lists all of the devices available and the main application with protection type.
