Electrical Enclosures

Polycarbonate vs ABS Enclosures: Impact, Heat, UV, and Application Inputs

NEMA Ratings For Enclosures

This guide supports planning and procurement. Confirm the final enclosure, material, rating, installation, and compliance requirements against project data, approved drawings, and supplier evidence.

Material selection follows the application

Polycarbonate and ABS are different plastic systems. The correct choice depends on impact, temperature, UV, chemicals, electrical function, mounting, machining, and service—not on a generic material label.

Questions for the design team

InputWhat to review
Impact and handlingCheck wall, cover, fasteners, mounting, and transport conditions.
Temperature and UVReview ambient, internal heat, sunlight, cycling, and material evidence.
Chemicals and cleaningConfirm compatibility of body, gasket, hardware, and finish.
ModificationReview cutouts, edge treatment, sealing, and post-modification evidence.

Provide the complete environment and equipment data. Do not claim that one plastic is universally stronger or more suitable.

Use these inputs to prepare an evidence-based enquiry and confirm the final configuration with the responsible engineer and supplier.
