Overview

The ABB AST 35/38-2 CB is a feeder terminal designed for industrial power distribution in 2- or 3-phase busbar systems compliant with UL 508 standards. This terminal supports Miniature Circuit Breakers (MCBs) and E90 fuse disconnectors, making it ideal for motor control centers, switchgear, and panelboards. The terminal features a durable PA66 housing (gray RAL 7035), brass chassis, and zinc-plated steel terminal screws for reliable performance. It offers a protection degree of IP20 and supports conductor cross-sections from 6-50 mm² (10 AWG to 1/0 AWG) for solid/stranded copper wires and 6-35 mm² (10 AWG to 2 AWG) for flexible wires with ferrules. Electrical ratings include 1,000 V AC/DC (UL) and 1,000 V AC / 1,500 V DC (IEC) for voltage, with current ratings of 115 A (UL) and 160 A (IEC). Specified tightening torques ensure secure connections, and the pin length is designed for shock protection. Certified for CE, RoHS, and REACH compliance, this terminal is cULus listed under UL 508 for supplementary protection circuits.
