Siemens NFK3T100 is a 100-amp, 600-volt AC heavy-duty safety switch designed for reliable circuit disconnection and overcurrent protection in industrial power distribution systems. This NEMA 3R-rated, rainproof enclosure houses a three-pole, non-fusible disconnect switch with a 100,000 AIC short-circuit current rating, constructed from galvanized steel for corrosion resistance in outdoor or washdown environments. The switch complies with UL 98 and CSA C22.2 No. 4 standards, ensuring safe operation under fault conditions. It is typically used for service entrance, motor disconnecting means, or feeder isolation in commercial and industrial facilities requiring a robust, weatherproof disconnect solution.
