The SIEHFC366NR from Siemens is a robust 3-pole fusible disconnect switch designed for reliable performance in challenging environments. With a capacity of 600A at 600V and a NEMA 3R enclosure, it offers superior protection against dust and moisture. Ideal for various applications, including hot tub installations, with integrated neutral for added convenience.
The Siemens HFC366NR is designed to accept Class R (RK1/RK5) or Class J fuses up to 600A, 600V, depending on the fuse reduction inserts used. We recommend verifying the exact fuse class against your application's overcurrent protection requirements and local CEC code. Contact our team if you need help selecting the correct fuses.
The NEMA 3R enclosure and 600V/600A rating make the HFC366NR a strong candidate for service entrance or main disconnect applications in commercial and industrial settings. However, service entrance suitability must be confirmed against CSA certification markings on the specific unit and your local authority having jurisdiction (AHJ). Reach out to us and we can help verify the certification details.
The Siemens HFC366NR with integrated neutral is considered a specialty and sometimes hard-to-find item. Northern Breaker Group specializes in obsolete and difficult-to-source electrical equipment, and we maintain access to both new and reconditioned inventory.
