New D-Size Powerfast(TM) Modular Wiring System

TURCK announces its new D-Size (1-3/8 inch) powerfast™ modular wiring system, designed to handle high current applications for machine power distribution and motor control.

Aw 2186 Turck0122

The complete D-Size power distribution system includes 3- and 4-pin cordsets, receptacles and tees that provide up to 600 Volts and 30 Amps. Additional powerfast components include field wireables, closure caps and a tee with an integrated cable drop, which eliminates the need for two separate connectors. Through the use of standard and reducer tees, it is now possible to use a quick disconnect system to distribute power to multiple field devices along one main trunk cable, reducing labor and equipment costs.

The D-Size powerfast system may be used in place of traditional conduit installations and is compliant with NFPA 79 (National Fire Protection Association Electrical Standard for Industrial Machinery) standards. This scalable, modular wiring system is easy to change, modify and maintain, and it may eliminate the need for conduit and raceways. Cordsets are available with exposed-run PVC flexlife® cable--guaranteed to endure 20 million cycles of continuous twisting, flexing and bending--in 10, 12 or 14 AWG wires. All powerfast connectors carry IEC IP67, 68 and 69K environmental protection ratings, along with NEMA 1, 3, 4 and 6P protection.

The D-Size powerfast system offers male and female, straight and right angle connectors; standard and custom lengths; and pigtails or extensions. Additional options include nickel-plated brass, stainless steel or clear anodized aluminum coupling nuts and encapsulated mating receptacles, in both 1/2"-14 NPT and 3/4"-14 NPT mounting threads.
