Durakool

What Durakool does

Durakool is a UK-based manufacturer of electromechanical power switching components, operating as a brand within the Solid State Group corporate structure. Founded in 1935 and headquartered in Copthorne, West Sussex, with regional offices in Elkhart (US), Augsburg (Germany), and Madrid (Spain), the company employs 51–100 people and designs relays, contactors, and resistors used to switch DC power in automotive, energy storage, renewable energy, industrial, medical, defense, and consumer electronics applications.

The core product portfolio spans HVDC ceramic contactors (CHV, DEVR, DHVC series) rated up to 1500VDC and 1000A, low-voltage DC contactors (DLVC, DSC series) from 80A to 2000A, automotive and industrial relays in PCB, plug-in, and chassis-mount formats (DG, DC, DE, DM, DX, DTC series), and pre-charge/discharge resistors (XV series) from 20W to 2800W. Differentiated technologies include internal magnetic arc blowout for arc extinguishing during switching, sealed ceramic/inert-gas contact chambers for high-voltage isolation, dual coil economisers to reduce holding current and extend EV range, non-polarised bi-directional terminal designs, and T2+Ag composite contact materials for extended electrical life. Key product specifications include 1500VDC switching capability, inrush current withstand up to 45,000A (<1ms), and IEC62955 compliance for EV charging residual current applications.

Durakool operates a B2B hardware sales model with revenue generated from one-time product sales to OEMs and equipment manufacturers. Go-to-market combines direct sales via website enquiry forms with a global channel partner network, including Solsta (primary global distributor), Premier Farnell and RS Components (catalog distributors), American Electronic Components (North America), and regional distributors across 15+ European countries and Asia-Pacific markets. Pricing is quote-based and not publicly disclosed. Marketing is conducted through trade shows (Battery Show, iVT Expo, ACT Expo, Electronica), thought leadership articles authored by the product management team, and distributor-led technical seminars.
