Fan Favorite Siemens JXD63S400A – 400A 3 Pole Molded Case Switch

Built for commercial isolation, the JXD63S400A is a 400A, three-pole molded case switch from the Siemens Sentron series. It serves as a non-automatic disconnect with a fixed magnetic trip for high-level fault self-protection. This unit-mount JD frame device installs into Siemens panelboards and switchboards. This legacy model is officially replaced by the 3VA5340-1BB31-0AA0 (requires mounting kit). Rated for 600VAC and 250VDC, it is HACR rated and accepts standard JD frame accessories.
