E-abel’s NEMA 3 Electrical Enclosure is engineered for environments that require protection against rain, sleet, windblown dust, and external ice formation. Designed according to UL and ANSI standards, this enclosure is a reliable solution for both indoor and outdoor applications, particularly in projects where weather resistance and cost-effective durability are key.
Whether installed at a construction site, rooftop, or building perimeter, E-abel’s NEMA 3 enclosures provide essential protection for electrical and electronic components in moderate outdoor exposure.
Material Options: Cold-rolled steel or galvanized steel with corrosion-resistant coating.
Surface Finish: Electrostatic powder-coated (default RAL7035 light gray) or available in customized colors.
Drip Shield Top: Extended top flange to redirect rainwater away from the enclosure’s front access.
Gasket Sealing: Weather-tight gaskets around the door to prevent ingress of dust and precipitation.
Mounting Flange or Brackets: Welded or detachable wall-mounting flanges support secure installation.
Secure Closure: Quarter-turn latch or padlockable handle for restricted access.
Weather Protection: NEMA 3-rated housing ensures protection from falling rain, sleet, snow, and windblown dust.
Ice-Resistant Design: Maintains integrity even when ice forms on the enclosure exterior.
Reinforced Door Structure: Minimizes deformation and ensures long-lasting door sealing.
Universal Configuration: Compatible with mounting backplates, DIN rails, or terminal blocks.
Versatile Installation: Supports wall, pole, or floor-mounted installations depending on application needs.
Standards Compliance: Meets NEMA 3 requirements and ANSI/IEC safety standards for electrical enclosures.
Case: A general contractor uses E-abel’s NEMA 3 enclosures to protect temporary power equipment from rain and dust on active job sites.
Case: Building automation engineers mount HVAC relay panels in rooftop NEMA 3 enclosures to secure controls from weather exposure.
Case: Enclosures used to house pump controllers for irrigation systems, guarding against dirt, insects, and water spray in open fields.
Case: Solar EPCs install NEMA 3 enclosures as load-break disconnect panels for residential and small commercial solar systems.
Case: Property managers use NEMA 3 panels to house timers and contactors for outdoor lighting systems on warehouse buildings.

Custom dimensions, mounting options, and material finishes are available upon request.
Mounting: Ensure level installation on a wall or pole using provided mounting flanges.
Sealing: Check gasket compression upon closure to maintain weatherproof seal.
Cable Routing: Use appropriate outdoor-rated glands; seal entries to maintain NEMA 3 rating.
Inspection: Regularly inspect gasket integrity and hardware tightness in seasonal environments.
Cleaning: Wipe with a damp cloth; avoid high-pressure hosing which may exceed NEMA 3 limits.
