What Katko does

Katko Oy is a Finnish family-owned industrial manufacturer, founded in 1940 and headquartered at Ruosilantie 2, Helsinki, that specializes in electrical switching and isolation technology for demanding and failure-intolerant applications. The portfolio spans four certified product families — IsoSafe enclosed isolators (including EMC, ATEX/IECEx hazardous-area, firerated, changeover, bypass, motor control, and UL/cUL disconnects, 10-1600A), LoadSafe load break and changeover switches (16-800A, including door-mounted and UL 98 variants), ConnectSafe terminal blocks, cable connectors, and installation enclosures, and FuseSafe switch fuses and fuse boxes — plus an accessories line and the heritage-oriented KATKO Classic recycled-aluminium sub-brand, totaling more than 2,745 SKUs. Manufacturing is anchored in Finland with additional production through Katko Poland, and products carry ATEX, IECEx, UL/cUL, UL 98, UL 60947-4-1A, and firerated certifications, positioning Katko for regulated industrial, power distribution, building, process industry, ventilation, and renewable energy installations.

The company generates revenue almost exclusively through hardware product sales, priced on a quote/project basis and distributed through three concurrent channels: a direct e-commerce storefront (shop.katko.com) requiring account login, a structured KATKO Channel Partner Program for distributors and wholesalers, and direct regional sales coverage via Sales Directors and Managers responsible for Finland and the Baltics, the UK, and Sweden, supplemented by strategic regional distributors such as Solar Group (Nordics) and Africa Drives (Morocco). Customer demand is diversified across six end-use segments — buildings and installations, industrial and harsh environments, process industry, power distribution, ventilation and clean air systems, and renewable energy — with no named end-customer logos disclosed. Go-to-market activity is supported by digital marketing (website, newsletter, LinkedIn, Facebook, YouTube), industry events, and engineering-software integration via the EPLAN Data Portal. Ownership remains entirely family-controlled with no institutional or private-equity backing disclosed.

Product overview

Katko is a Finnish family-owned company specializing in industrial electrical equipment with over eight decades of experience. The company offers a comprehensive portfolio of safety switches, isolators, and electrical connection solutions organized into four main product families: IsoSafe (enclosed isolators and safety switches), LoadSafe (load break and changeover switches), ConnectSafe (connectors, terminal blocks, and installation enclosures), and FuseSafe (switch fuses and fuse boxes). The IsoSafe family includes standard enclosed isolators (10-1600A), EMC isolators, ATEX and IECEx hazardous area isolators, firerated isolators, changeover switches, bypass switches, motor control switches, and UL/cUL listed disconnects. LoadSafe covers load break switches (16-800A), door-mounted switches, changeover switches, and UL98-listed variants. ConnectSafe provides terminal blocks, cable connectors, installation enclosures, and UL-listed terminal blocks. FuseSafe offers open type and enclosed switch fuses plus fuse boxes. All products are engineered and manufactured in Finland with a focus on reliability for demanding applications including industrial environments, power distribution, renewable energy, and building installations. A dedicated accessories line and the heritage-focused KATKO Classic sub-brand complete the portfolio.
