Overview

The nVent HOFFMAN A24NTMA3 Terminal Block Bracket Kit provides robust, versatile mounting supports for terminal blocks in industrial enclosures. Designed for Type 4, 12, and 13 enclosures, this kit fits 24.00-inch (610 mm) enclosures and includes three white steel brackets with a pretreated finish for corrosion resistance. Each bracket assembly mounts parallel to the A or B dimension of the enclosure, allowing flexible installation for horizontal or vertical terminal strap orientation. The kit does not include terminal blocks or straps, which must be ordered separately based on enclosure dimensions and mounting requirements. Compatible with large Type 1 enclosures, Type 3R hinged cover lift-off enclosures, and two-door Type 12 wall-mounted enclosures, this solution simplifies wiring and supports future expansions. Brackets are secured to collar studs using standard hardware, and straps can be positioned anywhere along the brackets for customized terminal block layouts. Ideal for industrial control panels, junction boxes, and electrical enclosures where organized wiring and modular mounting are critical.

  • One bracket is required for each row of collar studs parallel to the brackets
