SPDL – Reyrolle Product Introduction
The history of Reyrolle with over 100 Years of Experience
Reyrolle has been synonymous with electrical protection devices in the sectors of sub-transmission, distribution, and industrial applications for decades. Historically, Reyrolle relays, initially sold mainly in traditional markets, 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 portfolio
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 differential” 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:
