Scope

These standards apply to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72.5 kV. As UL and CSA are not a member of CENELEC these two are not according to the European approval marks. Wherever possible Object SCHURTER want to acquire the combined cULus approval mark: The object of these standards is to give: a) Definitions for degrees of protection provided by enclosures of electrical equipment as regards: 1. Protection of persons against access to hazardous parts inside the enclosure 2. Protection of the equipment inside the enclosure against ingress of solid foreign objects 3. Protection of the equipment inside the enclosure against harmful Since Aug. 1st. 2003 the Chinese approval mark is required for a lot of effects due to the ingress of water. products to import to China. SCHURTER strives to get the approvals b) Designations for these degrees of protection. for the concerned products. c) Requirements for each designation. d) Tests to be performed to verify that the enclosure meets the requi- rements of these standards.

Information about IP protection levels may vary depending on moun- ting or application for the various components. Following explanations are supplemented for this purpose.

There are cases where more than one IP value is mentioned for a product. Then this values are separated by a slash or by the term "or". This information is given for families or on series level to indicate that there are different variants with respective IP protection degrees. In some cases there will be further information about the respective con- ditions to ensure the tightness said. e.g.. 40 / 54 with sealing kit

This is basically the opposite to the mounting of the front side.

The protection against electric shock on electric equipment as well as their components are divided into the following parts:

The piezo disc is connected to the terminals 1 and 2. The electric circuit to be switched is connected at the terminals 3 and 4. This can be either direct voltage (DC) or alternating voltage (AC). If a pulse is applied to the piezo disc, terminal 1 becomes positive in relation to terminal 2 due to the voltage generated. The integrated switching ele- ment controls the electric circuit to be switched. In the neutral position of the piezo switching element, the terminals 3 and 4 are non-conductive, and initial switch resistance is > 10 MOhm. When the piezo disc is actuated, the initial switch resistance is redu- ced to < 20 Ohm.
