The unit measures 35.77 x 35.8 x 11 inches and supports currents of 400 to 800 Amps. It features overlapping double doors with a three-point latch, lift-off hinges, and a factory-installed wiring bus. Certified under UL 50, UL 414, and CUL standards.

Feature Summary

• Provides Type 3R protection suitable for outdoor and indoor environments
• Includes a factory-installed wiring bus for 400-800 Amp applications
• Features overlapping double doors with a three-point latch mechanism
• Constructed from 14-gauge galvanized steel with a durable powder-coated finish

Applications

• Installation with window-type current transformers
• Outdoor electrical distribution environments requiring weather protection
• Indoor industrial settings needing robust enclosure protection
• Current measurement systems operating between 400 and 800 Amps

Procurement Notes

Verify that the specific installation requires Type 3R protection and accommodates window-type current transformers. Confirm the physical dimensions of 35.77 x 35.8 x 11 inches fit the designated space. Ensure the application current falls within the 400 to 800 Amp range supported by the factory-installed wiring bus. Check for necessary certifications such as UL 50 or CUL compliance in your region before ordering.

Selection Notes

Select this model when heavy-duty weather resistance is required for current transformer installations. The galvanized steel construction offers superior durability compared to standard painted enclosures. The integrated wiring bus simplifies installation by eliminating the need for separate bus bar procurement. Consider the double-door design if frequent access to internal components is anticipated.

Part Context

This component belongs to the nVent Hoffman A800HCT series of current transformer cabinets. These units are specifically engineered for high-amperage applications, distinguishing them from general-purpose NEMA enclosures. The series focuses on providing pre-configured solutions for metering and protection devices, ensuring compatibility with standard window-type CTs without custom fabrication.
