Schneider Electric MG17446 Molded Case Circuit Breaker

Schneider Electric’s Square D Multi9 MG17446 is a 2-pole molded case circuit breaker rated at 15 A for 480Y/277 V operation, designed for use as a compact protective device in 480 V distribution panels and control circuits. This UL 1077-listed C60 (C-curve) breaker delivers up to 5 kA of short‑circuit interrupting capacity, making it suitable for loads with moderate inrush while providing reliable overcurrent protection. As part of the Multi9 MG family, MG17446 combines a small 2‑pole footprint with a 15 A rating to protect branch circuits in industrial and commercial environments powered by 480 V systems. Typical applications include lighting, small motors, and auxiliary loads within 480Y/277 V distribution networks where precise, predictable protection is required. When selecting components, ensure panel compatibility with the MG/Multi9 line and confirm that the 2P, 15 A, 480Y/277 V, C60 specifications meet your system’s electrical design and protection requirements.
