Contact ratings do not apply to Logic Level Contacts (C320MSC3L) or internally mounted auxiliary contacts (C320MSC8).

IEC Enclosure Classification

The degree of protection is indicated by two letters (IP) and two numerals. International Standard IEC 529 con-tains descriptions and associated test requirements that define the degree of protection each numeral specifies. The following table indicates the

general

degree of protection:

Table 38-2. First Numeral

Table 38-3. Second Numeral

Example:

IP41 describes an enclosure that is designed to protect against the entry of tools or objects greater than 1 mm in diameter and to protect against verti-cally dripping water under specified test conditions.
