The Schneider Electric Square D PowerPact D-Frame molded‑case circuit breaker, model DGA34150E53, is a 3‑pole protection device rated for 150 A at 480 VAC three‑phase service and built for industrial power distribution. Part of the PowerPact D‑Frame family, it uses the STR53 trip unit to deliver long‑time, short‑time, and instantaneous protection with a 100% rated continuous current, supporting dependable feeder protection in demanding environments. This I‑Line style plug‑in MCCB is UL listed, features load‑side lug terminals for straightforward wiring, and delivers up to 35 kA interrupting capacity at 480 V, making it suitable for circuits with substantial fault currents. For wiring, the terminal supports copper or aluminum conductors with a per‑terminal range of 2–600 Cu or 2–500 Al. The 3‑pole design protects three‑phase circuits and is commonly employed in main distribution panels, motor control centers, and process‑automation feeders where precise, time‑staged protection is essential. When selecting this model, confirm the STR53 series trip characteristics and ensure compatibility with your panel’s I‑Line plug‑in mounting footprint for a standard, code‑compliant installation.
