These fittings are designed to reduce strain, ease installation
Kopex-Ex ISR strain-relief fittings (photo) are designed to secure tray cables, portable cords and other unarmored cables in a wide array of industrial applications. They are IEC-Ex-, ATEX-, CSA- and UL-certified. These fittings feature an internal clamping mechanism that reduces the need for additional external clamping, thereby reducing installation time and cost, says the company. This design enables the industrial strain-relief fittings to comply fully with pullout requirements specified by the International Electrotechnical Commission (IEC), without the need for external clamping where the cables exit the enclosure. The design also ensures that pulling and twisting will not affect the terminations. — Thomas & Betts Corp., a member of the ABB Group, Memphis, Tenn.
