What criteria are used to classify NEMA enclosure types?
NEMA 1 Enclosures. Provides a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects.
What is a NEMA rated enclosure?
NEMA is a rating system for equipment that might be exposed to liquids, rain, ice, corrosion and contaminates such as dust. Protects against dust, light, and indirect splashing but is not dust-tight. Primarily prevents incidental contact with the enclosure equipment.
What does NEMA 4X enclosure mean?
The NEMA 4X definition, as established by the National Electrical Manufacturers Association, is a rating for an outdoor electrical enclosure that has the following protective qualities: Includes a gasket designed to protect against liquid and solid ingress.

What does NEMA 12 enclosure mean?
The NEMA 12 rating is a common NEMA rating used for devices that need moderate indoor protection against dust and liquid ingress. It’s a good choice for when you need basic protection at an affordable price. A NEMA 12 rated enclosure should protect the device inside against: Accidental personnel contact.
What is NEMA certification?
The National Electrical Manufacturers Association (NEMA) defines standards used in North America for various grades of electrical enclosures typically used in industrial applications. Each is rated to protect against personal access to hazardous parts, and additional type-dependent designated environmental conditions.
What is a NEMA 8 enclosure?
Type 8 NEMA enclosures are defined as: – Type 8 enclosures are intended for use indoors, in the atmospheres and locations defined as Class 1, Division I and Group A, B, C or D in the National Electrical Code.
What do NEMA numbers mean?
The NEMA (National Electrical Manufacturers Association) pattern and numbering system is made up of four main identifiers. The second identifier is a number. The first number in a NEMA listing determines the voltage rating. A 5 represents a voltage rating of 125 VAC, while a 6 identifies a rating of 250 VAC.
What is a NEMA 7 enclosure?
NEMA 7 enclosures are designed to contain an internal explosion without causing an external hazard. These enclosures are intended for indoor use in hazardous locations classified as Class I, Division I, Groups A,B,C, or D.
What is type2 enclosure?
Type 2 Enclosures constructed for indoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); and to provide a degree of protection with respect to harmful …
What are the NEMA standards?
What is NEMA ICS 6 enclosure?
NEMA standard ICS 6 categorizes enclosure types according to their ability to protect against damage due to substances such as water, dust and corrosive chemicals. A new review of these standards is published every five years.
What is a NEMA 6 enclosure?

What is NEMA type 1 enclosure?
NEMA 1 type of enclosure is typically a simple box with a screw cover and no sealing gasket. NEMA 1 enclosures are used inside buildings for electronics and small NEMA 1 enclousures might be placed inside other enclosures.
What do NEMA enclosure designations mean?
The NEMA enclosure description is similar to the IEC Index of Protection (IP) code. The NEMA designations are more descriptive and general, whereas the IEC IP codes are more precise and narrowly defined by a 2-digit code, with the first digit defining how well protected the motor is from solid objects and the second digit describing how well protected the motor is from moisture.
What is the difference between NEMA 3 and NEMA 3R enclosures?
NEMA 3R: Same as NEMA 3 but without the protection against windblown dust. The standard doesn’t say this, but typically the difference is that there is no gasketing on NEMA 3R enclosures. NEMA 3S: Same as NEMA 3 but adds the provision that external mechanism remain operable when ice laden.
What does NEMA stand for and what does it do?
NEMA stands for National Electrical Manufacturers Association and is an organization developed to form the technical standards for the manufacturing of electrical equipment and medical imaging equipment. NEMA works to set industry standards for safety, innovation, interoperability, environment, and market enhancement of our industry.
