SER

What SER does

SER (Société Électrique du Rhône), founded in 1974 and headquartered in Belleville-en-Beaujolais, France, is a B2B custom manufacturer of low-voltage electrical switchboards and automation cabinets. Its core products are TGBT (main low-voltage distribution boards), tableaux divisionnaires (sub-distribution boards), tableaux constructeurs (custom constructor boards) and armoires d'automatisme (automation control cabinets), all designed and built in-house to NF EN 61439-1-2 and NF C15-100 standards using components from Schneider Electric, Legrand, ABB and Socomec. SER produces approximately 2,500 cabinets per year for ~250 customers with a staff of ~70 employees.

The company targets French tertiary buildings, data centers, industrial sites, mobility infrastructure and nuclear facilities, with primary customers being large French multi-technical contractors and industrial clients such as SPIE, Eiffage, Engie Ineo, SNEF, Vinci Énergies and Bouygues. Reference projects include a 4,000A replacement switchboard suite for Hôpital Saint Joseph in Marseille (powering 7 operating theaters), underscoring the firm's positioning in critical-power, code-compliant, custom-engineered installations.

SER operates as the tertiary-sector specialist within LesBienCâblés, a French industrial group formed in 2023 by uniting SER, SATE (Dax) and TEEI (Nancy) — three historic panel builders with a combined ~130 employees, ~€40–45M revenue and over 120 years of cumulative expertise. Revenue mechanics are entirely project-based, quote-driven and span custom design, fabrication, on-site installation, commissioning and after-sales maintenance, with multi-year contract cadences. Distribution is exclusively direct field sales; there are no resellers or e-commerce channels. The group is ISO 9001:2015 and ISO 14001:2015 certified, and SER holds the EcoVadis Gold Medal (2026, 79/100, top 2% of sector).
