Ratings and deployment
Rated at 277 VAC with a 6 kA interrupting capacity, this breaker handles fault currents typical of commercial and light industrial branch circuits. The 2-pole configuration suits 480Y/277 VAC systems where line-to-neutral loads need overcurrent protection on both phases. DIN-rail mounting means it clips into the same footprint as other System pro M compact breakers — no panel rework if you're swapping in a Curve D for a C or B.
