Square D EGB24090 Two Pole Industrial Circuit Breaker

Square D by Schneider Electric EGB24090 is a two-pole molded-case circuit breaker (MCCB) in the E-Frame family, rated for 90 A on 480Y/277 VAC circuits. It provides thermal-magnetic protection with an interrupting capacity of 35 kA at 480 VAC (65 kA at 240 VAC), enabling operation in high‑fault‑current environments. This bolt-on, TAA-compliant device is designed for panelboard use and is commonly installed in NF panelboards to protect feeders and multiwire branch circuits in commercial and light industrial power distribution. Its two-pole construction ensures simultaneous opening of both conductors for safe isolation of 480Y/277 VAC circuits, and its E-Frame design is compatible with a range of Square D NF panelboard configurations. This model is used in environments requiring reliable protection for heavy loads and motors where specific trip characteristics and high interrupting capacity are essential.
