What Cirprotec SL does
Cirprotec SL is a specialist Spanish manufacturer of lightning and surge protection equipment for electrical installations, founded in 1993 in Terrassa (Barcelona) and operating as a wholly-owned subsidiary of Mersen Group since 2014. Its product portfolio covers transient surge protective devices (SPDs/DPS) for AC power lines in IEC Types 1 through 3, permanent overvoltage protectors (POPs), combined POP+DPS devices, ESE/PDC lightning rods (Nimbus range), and continuous monitoring devices for earthing systems (G-CHECK, SAFEGROUND) and insulation (ISO-CHECK). The company also offers dedicated product lines for photovoltaic and battery energy storage systems, electric vehicle charging infrastructure (EV-CHECK), LED outdoor lighting, and signal/data lines.
The technical foundation rests on six registered/world patents — most notably SAFEGROUND (integrated earth-monitoring SPD), V-CHECK (first combined transient and permanent overvoltage protector, 2004), EGARA (new-generation SPD for energy-transition applications), Nimbus R (remote-verifiable lightning rod), EV-CHECK (EV-charging SPD), and G-CHECK (continuous earthing controller) — backed by an in-house overvoltage and lightning testing laboratory established in 1999 and now exceeding 1,000 m². All manufacturing is performed in Spain with 100% tested production processes and multi-jurisdiction certifications (AENOR, DEKRA, UL, ENAC, Bureau Veritas, IEC, EN, NF C 17-102, UKCA, CE). The company reports more than 45,000 Nimbus lightning rods installed globally and over 50% of sales in renewable energy markets.
Commercially, Cirprotec operates a sales-led B2B model with quote-based pricing (no public list prices) targeting installers, electrical contractors, building managers, and industrial facilities. Distribution combines a direct sales team in Spain with a network of authorized regional distributors across Australia, Colombia, Ecuador, Morocco, South Africa, and the United Kingdom. The go-to-market emphasizes personalized technical consultation, free engineering tools (Nimbus Project Designer software), participation in standards committees, and presence at industry trade shows such as Genera. Customer concentration is spread across residential/commercial/industrial buildings, PV/BESS, EV charging, LED lighting, and telecom/data verticals.
