CTMB4001LS

Overview

The nVent Hoffman CTMB4001LS is a current transformer mounting base designed for commercial enclosures. Constructed from 12-gauge galvanized steel, it features an electrically isolated mount and termination platform. The unit includes mechanical lugs and studs to accommodate conductor connections. It is suitable for use with 1/2-inch studs on 1-3/4-inch centers and aligns with pre-punched holes in CT enclosures. The assembly supports up to 400A applications.

Feature Summary

• Electrically isolated mount and termination platform
• Pre-punched mounting base holes for alignment with CT enclosure studs
• Combines mechanical lugs and studs for versatile conductor connection styles

Applications

• Commercial electrical enclosures
• Current transformer metering installations
• Panel building requiring isolated CT mounting bases

Procurement Notes

Verify the specific conductor connection style required for your application, as variations exist including models with mechanical lugs or specific stud configurations. Confirm compatibility with existing CT enclosure pre-punched hole patterns. Ensure the 12-gauge galvanized steel construction meets environmental protection standards for the installation site. Check if additional hardware or separate ordering of compatible HP nozzles is necessary for complete assembly.

Selection Notes

Select this base when an electrically isolated mounting solution is required for current transformers within commercial enclosures. The 12-gauge galvanized steel provides structural integrity and corrosion resistance. Consider the available conductor connection options, such as mechanical lugs versus stud-only configurations, to match the specific wiring requirements of the panel design. Ensure the 1/2-inch stud spacing aligns with the target enclosure model.

Part Context

This component belongs to the nVent Hoffman A90CM series of current transformer bases. These bases are engineered to facilitate the integration of metering devices into standard commercial electrical panels. The product line offers various configurations to suit different conductor sizes and enclosure types, ensuring standardized mounting practices across industrial and commercial electrical infrastructure projects.

Replacement Considerations

Consult official nVent Hoffman documentation for direct substitute part numbers. Verify that any replacement maintains the 12-gauge gauge, galvanized finish, and electrical isolation characteristics. Ensure the new part matches the stud spacing and lug configuration of the original design.
