Eaton DH463FDK Fusible Safety Switch - UL Listed
Part Number: DH463FDK
Quick Summary
DH463FDK Fusible Safety Switch is a robust isolation device that provides reliable circuit isolation for heavy-duty industrial equipment in manufacturing plants. Engineers often confront downtime and maintenance overhead when selecting switches that don’t deliver durable enclosures, wiring versatility, or field service flexibility. UL Listed and NEMA 12/3R protection help ensure compliance in harsh environments, while field-modifiable NEMA 3R rainproof capability adds installation flexibility. Designed for 480 and 600 V systems with up to 75 hp, it delivers safer starts, simpler maintenance, and predictable performance for your production line. Its four-pole, four-wire arrangement and Class H fuse support consistent protection across motor loads, reducing spare parts and field troubleshooting.
