Thank you.
but there is no label or marking on the switch to indicate that'' this switch is hermetically sealed'' or this is rated for C1D2..
but based on switch construction, it is hermetically sealed and from manufacture datasheet we can find that is hermetally sealed.
what is you opinion??
SO-why didn't you say all that in the first place?
Nevertheless, the key term in the Section 501.125(B) clause "... unless such sliding contacts, switching mechanisms, and resistance devices are provided with enclosures identified for Class I, Division 2 locations in accordance with 501.105(B)" is
identified (not listed or
labeled). Since the switch is not specifically required to be
listed or
labeled and referring to Section 501.105(B)(1)
Exception part (2), according to the manufacturer's datasheet, the contacts are
hermetically sealed and are thus
suitable (identified) for Class I, Division 2. See also Section 500.8(A)(3).
