Enclosure for Indoor and Outdoor Use

The VEVOR NEMA 4X fiberglass electrical box is built for indoor and outdoor installations where equipment must stay dry and clean. Its SMC construction resists corrosion and impact in harsh environments. Installers mounting junction boxes on walls will find the included galvanized back plate and guide rails ready for immediate fitting.

IP66 and NEMA 3 3X Protection Limits

The enclosure meets IP66, blocking powerful water jets and dust ingress when the lid is closed and the sealing strip is intact. NEMA Type 3 and 3X ratings confirm suitability for windblown dust, rain and external ice formation. Protection applies only while the door remains latched; open-door exposure voids the rated seal.

Upgrade from Non-Rated or Lower-Rated Boxes

This unit replaces unrated steel or plastic boxes that cannot guarantee IP66 or NEMA 3X performance in wet or dusty conditions. The jump is worth it when regulations or site specifications demand documented ingress protection and a lockable hinged lid for security. It is not for applications requiring larger internal volume or higher pressure ratings.

Questions about this item

How do I decide between the outer dimensions of 40 x 30 x 20 cm and the inner dimensions of 37 x 29 x 19 cm for my installation?

Use the outer dimensions of 40 x 30 x 20 cm for wall mounting clearance and the inner dimensions of 37 x 29 x 19 cm to verify your components fit inside the enclosure.

What does the IP66 rating mean for daily outdoor use of this enclosure?

IP66 means the box is dust-tight and protected against powerful water jets, so rain, hose-downs and wind-blown dust will not enter when the lid is closed.

What protection does the NEMA Type 3, 3X rating add beyond IP66?

NEMA Type 3, 3X adds corrosion resistance and protection against wind-blown dust, rain and sleet, complementing the IP66 water-jet and dust seal.
