Technical Information

The degrees of protection provided by enclosures are defined by standards IEC 60529 (IP) and IEC 62262 (IK).

The IP rating gives the degree of protection offered by the enclosure against access to dangerous parts within the enclosure, e.g. live circuits, moving parts, etc.

Degrees of Ingress Protection are indicated by the letters IP followed by two characteristic numerals.

The first numeral refers to ingress of solid bodies, e.g. dust, tools, fingers, etc.

The second numeral refers to ingress of liquids.

A third numeral refers to protection against external mechanical impact is indicated by the letters IK.

Universal Enclosures mild steel enclosures are coated with thermosetting polyester resins based powder coating modified by epoxy resins, designed for aesthetics and to help prevent corrosion.

The performance of this coating is superior to conventional epoxy powders in terms of: Colour stability, temperature resistance and weather resistance.

Colour: RAL7035 Light Grey, structured finish.

Polyester base coating properties

Nuclear decontamination: Applicable to colours RAL7035 Light Grey, standard NFT 30901.

Accelerated aging: Standard IEC 62208: 500 h UV according to ISO 4892.

Fire behaviour: Class M1 (self-extinguishing material); Class M0 (for coating on a metal base).

Coating thickness: 50 – 70 microns.

ETA Powder-coating Process


For the first time ever, the cathodic electrocoating process has been applied to the painting of enclosures and electrical panels. The system is called E DUP – unique to ETA.

The new E DUP treatment – Double Layer Protection – includes a first layer of paint using cathode electrophoresis with epoxy resin and a topcoat of epoxy-polyester thermosetting powder, according to the standard ETA electrostatic cycle (Colour RAL7035, textured).

This treatment – which is standard for all of ETA’s painted solutions – uses a primer of undisputed chemical and physical properties, to ensure better product performance. The goal is to offer increasingly reliable, performing and suitable solutions for a variety of environments and applications.

The highly automated and innovative process has made it possible to obtain results of high qualitative characteristics, reducing the thickness of topcoats and eliminating wasted paint, in full respect of environmental sustainability.
