It handles 277 VAC and 500 VDC circuits, with an interrupting capacity of 6 kA AC and 10 kA DC. The DIN-rail mount fits standard panel enclosures.
Trip Curve K and application fit
Trip Curve K provides a magnetic trip threshold of 8 to 12 times the rated current, which means it tolerates the inrush of inductive loads like motors and transformers without nuisance tripping, while still protecting against short circuits. For a 16 A breaker, that magnetic pickup starts around 128 A. This makes it a fit for motor branch circuits and transformer primary protection where a standard Curve C might trip on startup.
DC rating and interrupting capacity
Rated for 500 VDC with a 10 kA interrupting capacity, this breaker handles DC bus circuits in drives or solar combiner boxes. The 6 kA AC rating at 277 VAC covers single-phase line-to-neutral applications. The DC interrupting rating is higher than the AC rating, which is typical for breakers designed to break DC arcs.
