STS324FD3

The STS324FD3 by Eaton Cutler-Hammer serves as a durable fusible safety switch, ideal for electrical systems requiring reliable interruption capabilities. This unit is configured as a three-pole single-throw switch, capable of managing an amperage rating of 200 A at a voltage rating of 240 V AC. Its sturdy construction ensures long-lasting performance in demanding applications while preventing electrical faults.

This safety switch operates on a coil voltage of 120 V AC and can handle standard frequencies of 50 or 60 Hz. Furthermore, its minimum coil operating voltage is set at 66 V AC when running at 60 Hz, providing compatibility across different operational settings. The performance of the switch is evidenced by a maximum response time of just 0.05 seconds (50 ms), which is critical when encountering electrical surges or faults. Additionally, its arcing time remains exceptionally low, reported at less than 10 ms, further minimizing potential disruptions.

Designed without a neutral configuration, the STS324FD3 employs a fusible protection type to ensure safe operation. It adheres to the Class H standard fuse classification, providing a reliable protective solution. Moreover, it allows for optional fuse classes such as Class R, Class J, or Class T, offering adaptability to various safety requirements. With a weight of 65 lbs, this device is both robust and compact, fitting adequately into different installations while maintaining compliance with rigorous safety standards.
