ID365NF – SIEMENS 3P400A 600V NON FUSED DISCONNECT NEMA 1

The 'NF' in ID365NF designates it as non-fused, meaning the switch provides power isolation only and does not include fuse clips or fusible elements. A fused version would incorporate fuse holders to provide both disconnection and overcurrent protection in a single enclosure. With the ID365NF, you must ensure adequate overcurrent protection is provided by an upstream device such as a circuit breaker or fused switch.

No — NEMA 1 is rated for indoor, dry locations only, protecting against contact with enclosed equipment but offering no protection against moisture, dust, or weather. For outdoor or wet/damp environments, you would need a NEMA 3R or NEMA 4/4X rated disconnect. Contact our team and we can help source the appropriate enclosure rating for your application.

Availability of specific Siemens ID-frame disconnect models can vary, and some configurations enter end-of-life status over time. Northern Breaker Group specializes in obsolete and hard-to-find electrical equipment — if the ID365NF is no longer available through standard distribution channels, we can often source it from our network or recommend a compatible current-production equivalent.
