A400HCTB

Overview

The Hoffman A400HCTB is a hinged current transformer cabinet constructed from galvanized steel with a polyester powder-coated ANSI 61 gray finish. It features a Type 3R rating for outdoor protection and includes a 400-amp bar-type mount with line/load lugs. The enclosure dimensions are 36.07 inches in length, 30 inches in width, and 11 inches in depth. It utilizes a quarter-turn latch lock mechanism and complies with UL 50 and CUL standards.

Feature Summary

• Hinged cover design for simplified access to internal components
• Bar-type mounting configuration with integrated line and load lugs
• Type 3R rated construction suitable for outdoor environmental exposure
• Galvanized steel body with durable polyester powder paint finish

Applications

• Protection and securing of instrument current transformers
• Outdoor electrical distribution installations requiring weather resistance
• Industrial power metering infrastructure housing

Procurement Notes

Verify the specific electrical rating requirements against the 400/800 Amp specification listed in official documentation. Confirm that the Type 3R rating aligns with the intended installation environment's weather exposure needs. Ensure the physical dimensions of 36.07 x 30 x 11 inches fit the designated mounting space. Check for compliance with local UL 50 and CUL regulations before finalizing procurement.

Selection Notes

Select this model when a hinged access method is preferred over removable doors for maintenance efficiency. Choose this unit if the application requires a pre-integrated bar-type mount with lugs rather than separate busbar assembly. Consider this option for outdoor sites where Type 3R weather protection is mandatory. Verify that the 400-amp capacity meets the circuit load requirements.
