Relpol SA

What Relpol SA does

Relpol S.A. is a Polish manufacturer of electromagnetic relays, solid-state relays, time relays, interface relays, monitoring relays, bistable relays, installation relays, railway relays, and complementary industrial automation components, operating continuously since 1958 and listed on the Warsaw Stock Exchange under ticker RLP. The company's core technology spans miniature relay series (RM84/85/87), industrial plug-in relays (R2N/R3N/R4N/R15/RUC), high-current relays up to 90A (R50A/R90A), solid-state relays for AC and DC applications (RSR20–95), and specialized railway-rated series (R15T/R2T/R3T/R4T) with mechanical shock and vibration resistance. Adjacent product lines include switching power supplies, surge protectors for AC/DC/PoE/signal lines, power controllers, installation contactors, MID-certified energy meters, multi-functional network parameter meters, astronomical and digital timers, PLC controllers (HX/MICRO-EHV+), and EV charging stations (GLB/TWIN/LS-4), all designed for DIN-rail or panel mounting and supported by a comprehensive socket and accessory ecosystem.

The company sells B2B through a multi-tier channel: regional technical-commercial offices across all 16 Polish voivodeships, a nationwide Polish trade partner network, an export department with regional partners across Africa, North America, South America, Asia, Europe, and Australia/Oceania, and a dedicated German e-commerce storefront at relpol24.de. Pricing is quote-based and not publicly disclosed, with revenue derived from hardware sales of relay families and complementary automation components, alongside light technical consulting for product selection. Target customer segments include industrial automation, electronics manufacturing, telecommunications equipment, railway signaling and safety systems, energy generation and distribution (including solar inverters and EV charging integrators), and building automation integrators. The technical sales motion is supported by parametric product search, downloadable CAD libraries integrated into WSCAD/EPLAN/PCSCHEMATIC design platforms, IEC/CE/UKCA/VDE/UL/cUL/CSA/MID/Lloyd Register/railway certifications, and trade-fair participation.

Relpol positions itself on 65+ years of focused relay manufacturing expertise, a comprehensive product portfolio spanning all relay types, continuous R&D-based product innovation, and a global certification footprint that lowers cross-border qualification friction for industrial OEM customers. The historical absence of disclosed funding rounds, M&A, or leadership transitions in the input data, combined with a publicly listed governance structure and registered share capital of 48,045,965 PLN, frames Relpol as a stable, mature, mid-market industrial components manufacturer with a defensive rather than high-growth profile.
