NEMA 250 Type 13 Enclosures
NEMA 250 addresses the ingress protection of enclosures for electrical equipment rated at 1000 Volts or less and intended to be installed and used in specific non-hazardous and hazardous locations. NEMA 250 has defined 20 different enclosure types.
NEMA 250 Type 13 enclosures are 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 circulating dust, lint, fibers, and flyings); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (dripping and light splashing); and, to provide a degree of protection against the spraying, splashing, and seepage of oil and non-corrosive coolants.
There are seven primary ingress protection tests associated with NEMA 250 Type 13 enclosures:
- Access to hazardous parts
- Ingress of solid foreign objects (falling dirt)
- Ingress of water (dripping and light splashing)
- Ingress of solid foreign objects (circulating dust, lint, fibers and flyings)
- Ingress of solid foreign objects (settling airborne dust, lint, fibers and flyings)
- Oil and coolant seepage
- Oil or coolant spraying and splashing
Keystone Compliance is a certified NEMA 250 testing lab. What sets Keystone Compliance’s NEMA testing apart is our experience in helping manufacturers determine ingress points in their products and also identifying potential solutions. We also have significant expertise in interpreting the NEMA 250 standard, including for NEMA 250 Type 13 enclosures. Just because some liquid or dust may enter an enclosure, does not automatically mean that the unit has not met the requirements. If the unit that requires testing is too large to move, no problem. We have experience completing ingress protection testing at the customer’s facilities.
