EXE255250120

Overview

The Hoffman Enclosures EXE255250120 is a NEMA 4X explosion-proof enclosure constructed from cast aluminum. It features a square design with dimensions of 25 inches in height, 25 inches in width, and 12 inches in depth. The unit includes a hinged door with a quarter-turn latch mechanism for secure closure. This enclosure is rated for Class I, Division 1 hazardous locations containing Group D flammable gases or vapors. It provides protection against windblown dust, rain, sleet, and hose-directed water, ensuring safe operation in industrial environments where explosive atmospheres may be present.

Feature Summary

• Explosion-proof construction designed for hazardous locations
• NEMA 4X rating for environmental sealing
• Quarter-turn latch door mechanism

Applications

• Housing electrical components in Class I, Division 1 areas
• Industrial facilities handling Group D flammable substances
• Outdoor installations requiring weather resistance

Procurement Notes

Verify that the specific installation site matches the enclosure's Class and Division ratings. Confirm that the internal equipment does not exceed the thermal limits defined by the manufacturer. Ensure that all conduit entries are properly sealed to maintain the explosion-proof integrity. Check for any required accessories such as mounting brackets or gland plates before finalizing the order.

Selection Notes

Select this model when a robust, weather-resistant housing is needed for hazardous area applications. Consider the internal volume requirements to ensure adequate space for wiring and component placement. Evaluate the need for additional knockouts or custom modifications based on the specific cabling layout. Compare alternative materials if corrosion resistance beyond standard aluminum is required.

Part Context

This model belongs to Hoffman's line of explosion-proof enclosures, which are engineered for safety in volatile environments. These units typically feature heavy-duty castings to contain internal explosions. The series is widely used in petrochemical, pharmaceutical, and manufacturing sectors where compliance with strict safety standards is mandatory.

Replacement Considerations

Direct replacements must match the exact dimensional footprint and mounting hole patterns. Verify that substitute models hold equivalent NEMA 4X and Class I, Division 1 certifications. Ensure the replacement material offers similar corrosion resistance and structural integrity.
