Scheider Electric Polyester Enclosures
Schneider Electric polyester enclosures are the ideal solution for protecting electrical and electronic installations. They are made from a special type of polyester reinforced with fiberglass—a material that is much stronger and more stable dimensionally than what is found in most everyday plastics. This lends the enclosures excellent mechanical strength and fantastic dimensional stability, two qualities that are absolutely necessary for the kind of long-term performance that is expected from an industrial electrical enclosure.
Polyester is a very poor conductor of electricity, and this makes it a great material to insulate electrical components in. The properties of this synthetic material enable it to conduct a very small amount of static electricity, much less than is conducted by the typical structural material with which it has been compared—a wall, for instance. When electrically powered units are assembled in a polyester enclosure and operated, any electricity conducted by the units can accumulate only on or in a polyester surface.

FAQs
What does an IK degree of protection and IP degree of protection mean?
The IK degree of protection indicates the resistance of an enclosure to mechanical impacts, while the IP degree of protection specifies the enclosure's ability to protect against ingress of dust and water.
Non-Metallic Enclosure Types
Characteristics of non-metallic enclosures:
NEMA 4x rating for outdoor use providing chemical resistance and protection from dust, debris, water and rain.
High insulation value, which provides insulation from cold and hot temperatures, but does not dissipate heat from inside the enclosure.
Non-conductive, meaning components cannot be grounded to the enclosure, but it still provides the same security and tamper resistance levels as metallic enclosures when properly locked.
Types of non-metallic enclosures:
Fiberglass
A thermoset polyester material reinforced with glass fibers. It is the most widely used non-metallic material in the industry. It has high impact strength and rigidity (dimensional stability), a superior working temperature range (-31˚F to 300˚F), excellent electrical properties, moisture and chemical resistance, as well as being cost effective.
Polycarbonate
High-performance thermoplastic resin processed by injection molding or sheet extrusion. It has superior impact resistance, good rigidity (dimensional stability), an extended temperature range (-31˚F to 180˚F), excellent electrical properties, fire retention, UV stability and corrosion resistance in some acidic surroundings. It is not suitable for environments with strong alkalis and organic solvents.
ABS or ABS blends
Acrylonitrile Butadiene Styrene is a common thermoplastic polymer processed by injection molding. It has high impact resistance, but less impact resistance in cold weather compared to polycarbonate, excellent electrical properties, superior chemical and moisture resistance, but a narrower temperature range than fiberglass (-40˚F to 248˚F).
Polyester
High-performance unfilled thermal plastic processed by injection molding. It has high impact resistance, but less impact resistance in cold weather than polycarbonate, excellent electrical properties, superior chemical and moisture resistance, but a narrower temperature range than fiberglass (-40˚F to 248˚F).
