Overview

The ABB TB57 is a 1-1/2 inch Form 7 conduit body engineered for Rigid and IMC conduit systems in industrial electrical installations. Constructed from durable gray iron, this conduit body features a triple-layer protective coating system: zinc plating for base corrosion resistance, a baked-on epoxy powder coat for exterior durability, and ABB’s proprietary BlueKote internal coating to reduce friction during wire pulling. The precision-cast and machined surfaces ensure smooth conductor paths, minimizing abrasion and facilitating safer, faster installations. With a cubic content of 27.50 cubic inches (450.64 cm³), the TB57 accommodates ample conductor volume for branch circuits, pull outlets, or 90° bends in conduit runs. The deep-slotted steel cover screws and neoprene gasket provide reliable sealing and quick access for maintenance or future modifications. Compatible with Rigid and IMC conduit, the TB57 meets UL 514B standards and is designed for long-term performance in harsh environments where corrosion resistance and mechanical integrity are critical. Ideal for connecting conduit sections, providing access for splices, or enabling easy wiring adjustments, this conduit body combines robust construction with practical features for industrial applications.
