Hello. I'm forced to use
this sensor in a C1D2 Environment. It has no listing at all - datasheet tells me that it's for ATEX Ex II 2G EEx d IIB + H2 T3 environment.
Is it possible to use this in C1D2? It runs at 24 V, max. <500 mA - nonincendive circuit? Or does 501.115(B)(3) apply?
Thanks!
Daniel
I suspect the OP meant 501.1
05(B)(3), [Without Make-or-Break Contacts].
This brings up one of the more unique differences between Division and conventional Zone (not US) concepts. Under NEC "Divisions", except for luminaires, where "General Purpose" equipment is permitted to be used, no special marking beyond its "ordinary use" is required for classified locations. [Section 500.8(C)(6)] Under IEC/CENELEC "Zones"
almost everything must be specifically marked for a classified location application; i.e. there is very little "General Purpose" material/equipment acceptable in IEC "Zones". (This is actually where ATEX came in, in the EU)
petersonra is right that ATEX means nothing in US/NEC domestic installations - unless a knowledgeable AHJ understands the markings and determines that the product is
suitable under Sections 500.8(A)(3) [manufacturer's evaluation] and 501.105 (B)(3) as an acceptable GP product. While I personally would have no problems with the product for the application, I wouldn't keep my hopes up.
That said, getting the product evaluated by one of the European associates of UL/FM/INTERTEK etc., and
listed/labeled by their US counterpart may be less expensive than expected. I have done this before.
