Product Description
The D400 NI unit utilizes the standard NEMA 4X housing and meets FM and CSA approvals for Non-Incendive applications. This unit also carries the Intrinsically Safe approvals as well. The detailed approvals are listed in the Approvals Details document linked above in the documentation section. Product performance specifications would be identical to the standard D400, but the NI approvals offer a real benefit to meet specific area classifications and are less expensive than a full EX-rated product.
