IP Ratings Chart - Protection against Solids and Water - NEMA Ratings Equivalent

Oct 12, 2026

A reference chart for IP ratings that explains the meaning of the first digit (protection against solids) and the second digit (protection against water), including level-by-level descriptions and example objects. It also provides NEMA enclosure type equivalents with short definitions, with notes that entries apply to non-hazardous and hazardous (classified) locations separately. The chart emphasizes approximate use and warns not to convert IEC to NEMA designations.

Hazardous (Classified) Locations

IP Ratings Chart First Digit: Protection against Solids | Level | Protection against | | Example of Object and Description | | --- | --- | --- | --- | |

0 | - | | No protection | | 1 | Solid objects > 50 mm | | Back of a hand; no protection against deliberate contact with a body part | | 2 | Solid objects > 12.5 mm | | Fingers or similar objects | |

3 | Solid objects > 2.5 mm | | Tools, thick wires, etc. | | 4 | Solid objects > 1 mm | | Most wires, screws, etc. | |

5 | Dust protected | | Ingress of dust not entirely prevented, but does not interfere with operation of the equipment | |

6 | Dust tight | | No ingress of dust, complete protection against contact | Second Digit: Protection against Water | Level | Protection against | | | | | Example of Liquid and Description | | --- | --- | --- | --- | --- | --- | --- | |

0 | - | | | | | No protection | | 1 | Dripping water | | | | | Vertically falling drops have no harmful effect | | 2 | Dripping water when tilted up to 15° | | | | | Vertically falling drops have no harmful effect when enclosure is tilted at an angle up to 15° from its normal position | |

3 | Spraying water | | | | | Water falling as a spray at any angle up to 60° from the vertical has no harmful effect | | 4 | Splashing water | | | | | Water splashing against the enclosure from any direction has no harmful effect | |

5 | Water jets | | | | | Water projected by a nozzle against enclosure has no harmful effect | |

6 | Powerful water jets | | | | | Water projected in powerful jets against enclosure has no harmful effect | | 7 | Immersion up to 1 m | | | | | Ingress of water in harmful quantity when enclosure is immersed in water (up to 1 m of submersion) | |

8 | Immersion beyond 1 m | | m | | | Depends on the specification of the manufacturer. Equipment may be hermetically sealed or it means that a certain amount of water can enter the enclosure without harmful effects | Copyright © INDUSTRONIC® 1 NEMA Ratings Chart with IP Rating Equivalents All enclosure types listed below are for use in non-hazardous (non-classified) locations. Use this table only as an approximate reference. Do not convert from IEC to NEMA designations. | Enclosure Type | IP Rating Equivalent | Short Definition | | --- | --- | --- | | 1 | IP10 | For indoor use, primarily to prevent accidental contact with the enclosed equipment to provide protection against limited amounts of falling dirt. | | 2 | IP11 | For indoor use, primarily to provide a degree of protection against contact with the enclosed equipment and against limited amounts of falling water and dirt. | |

3 | IP54 | For outdoor use, primarily to provide a degree of protection against rain, sleet, wind blown dust and damage from external ice formation. | | 3R | IP14 | For outdoor use, primarily to provide a degree of protection against rain, sleet, and damage from external ice formation. | | 3S | IP54 | For outdoor use, primarily to provide a degree of protection against rain, sleet, windblown dust and to provide for operation of external mechanisms when ice laden. | | 4 | IP66 | For indoor or outdoor use, primarily to provide a degree of protection against windblown dust and rain, splashing water, hosedirected water and damage from external ice formation. | | 4X | IP66 | For indoor or outdoor use, primarily to provide a degree of protection against corrosion, windblown dust and rain, splashing water, hose-directed water, and damage from external ice formation. | |

5 | IP52 | For indoor use, primarily to provide a degree of protection against settling airborne dust, falling dirt, and dripping noncorrosive liquids. | |

6 | IP67 | For indoor or outdoor use, primarily to provide a degree of protection again hose-directed water, and the entry of water during occasional temporary submersion at a limited depth and damage from external ice

FAQs

What does the first digit in an IP rating indicate?

It indicates protection against solids, such as different sizes of solid objects and whether dust ingress is limited or sealed.

What does the second digit in an IP rating indicate?

It indicates protection against water, including dripping, spraying, splashing, water jets, and immersion levels, based on the numeric level.

How are NEMA enclosure types related to IP ratings in this chart?

The chart lists NEMA enclosure types with corresponding IP rating equivalents and provides short definitions, but it specifies that the table is only an approximate reference and should not be used for direct IEC-to-NEMA conversion.
