IP Ratings Enclosures

Our Enclosures classifies follow IP Ratings

NEMACO™ has strong knowledge and experience in design, integration, and manufacturing of electrical enclosures according to the IP ratings’ system for research, commercial and industrial applications. Nemaco designs and integrates both the NEMA and IP standards to manufacture world-class electrical enclosure products.
We offer 5 level of protection, IP24, IP54, IP66, IP67, and IP68. Each type of enclosure provides the different level of protection against solid object and entry of liquid to hazard part (get into the enclosure).

**If you don’t know what is IP ratings, how they classify the level of protection for each type of enclosures please read our page for IP ratings’ definitions. This will give you very intensively explanations about each character in a combination of IP rating, including testing procedures for each protection.
If you are already familiar with IP ratings, NEMACO™ will expound our IP ratings enclosures below.

IP24 Enclosures


Ingress of solid objects: It gives limited protection against fingers or similar objects which are bigger or equal than 12.5 mm.

Ingress of liquids: It also gives protection against water splashing from any direction(shall have no harmful effect).

IP66 Enclosures


Ingress of solid objects: It gives a complete protection against the entry of dust.

Ingress of liquids: It also gives protection against powerful water jets projects to an enclosure from any direction.

Our IP66 Enclosures is approximately equivalent to NEMA 4 Enclosures and NEMA 4X Enclosures in term of protections. You can read about what is different between NEMA 4 and NEMA 4X Enclosure (NEMA 4 vs NEMA 4X) in our blog.

IP67 Enclosures


Ingress of solid objects: It gives complete protection against dust ingress.

Ingress of liquids: It also gives a protection against short periods of immersion in water up to 1 m. of submersion.

Our IP67 Enclosures is approximately equivalent to NEMA 6 Enclosures (depended on material thickness, a thicker material can be upgraded to IP68 Enclosures for more information please read) in term of protections.
We offer many types of enclosures below.

IP68 Enclosures


Ingress of solid objects: It gives a complete protection against dust ingress.

Ingress of liquids: It also gives a protection against long, durable periods (continuous) of immersion in water 1m or more depth. This means the equipment is hermetically sealed.

Our IP68 Enclosures is approximately equivalent to NEMA 6P Enclosures (depended on material thickness) in term of protections.

We offer many types of enclosures below.

IP RATINGS (Ingress Protection)
and what it means…

Nemaco™ has strong knowledge and experience in design, integration and manufacturing of electrical enclosures according to the IP rating system for research, commercial and industrial applications. The IP rating system was developed to provide general references for the design, materials, usage and safety considerations of electrical enclosures for manufacturing companies in the USA and other countries worldwide. Nemaco designs and integrates both the NEMA and IP standards to manufacture world class electrical enclosure products.

The IP Code (“international protection rating” or  aka “ingress protection rating“) consists of a combination of letters “IP” followed by two numerical digits (for example “65”) and sometimes an optional alphabetical letter. Per the international standard IEC 60529, the standard defines degrees of “ingress protection” against the intrusion or damage from solid objects, dust and water for the purpose of protecting electrical enclosures and equipment inside the enclosures (for example, electronics or electrical wiring). The IP rating standard was designed to provide detailed levels of “ingress protection” against objects, dust resistance, dripping water resistance to submersion waterproof.   Refer to the IP ratings and descriptions for more information.

First digit: Solid particle protection

The first digit of the combination

               IP66

defines the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

LEVEL
(FIRST DIGIT)
ENCLOSURE SIZE EFFECTIVE AGAINSTDESCRIPTION
0No protection against contact and ingress of objects
1> 50 mmAny large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part
2> 12.5 mmFingers or similar objects
3> 2.5 mmTools, thick wires, etc.
4> 1 mmMost wires, slender screws, large ants etc.
5Dust protectedIngress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.
6Dust tightNo ingress of dust; complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow.

Second digit: Liquid ingress protection

The second digit of the combination

               IP66

defines the level of protection that the enclosure provides against harmful ingress of water. The ratings for water ingress are not cumulative beyond IPX6. A device which is compliant with IPX7, covering immersion in water, need not be compliant with IPX5 or IPX6, covering exposure to water jets. A device which meets both tests is indicated by listing both tests separated by a slash, e.g. IPX5/IPX7.

LEVEL
(SECOND DIGIT)
PROTECTION AGAINSTEFFECTIVE AGAINST
0None-
1Dripping waterDripping water (vertically falling drops) shall have no harmful effect on the specimen when mounted in an upright position onto a turntable and rotated at 1 RPM.
2Dripping water when tilted at 15°Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position. A total of four positions are tested within two axes.
3Spraying waterWater falling as a spray at any angle up to 60° from the vertical shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with a counterbalanced shield.
Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Test b) is conducted (with shield in place) for 5 minutes minimum.
4Splashing of waterWater splashing against the enclosure from any direction shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with no shield.
Test a) is conducted for 10 minutes. Test b) is conducted (without shield) for 5 minutes minimum.
5Water jetsWater projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.
6Powerful water jets Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects.
6KPowerful water jets with increased pressure Water projected in powerful jets (6.3 mm nozzle) against the enclosure from any direction, under elevated pressure, shall have no harmful effects. Found in DIN 40050, and not IEC 60529.
7Immersion, up to 1 m depthIngress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).
8Immersion, 1 m or more depthThe equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion.
9KPowerful high temperature water jets Protected against close-range high pressure, high temperature spray downs.
Smaller specimens rotate slowly on a turntable, from 4 specific angles. Larger specimens are mounted upright, no turntable required, and are tested freehand for at least 3 minutes at distance of 0.15–0.2 m.

There are specific requirements for the nozzle used for the testing.

This test is identified as IPx9 in IEC 60529.
