Rated 12.5 A at 40 °C, it holds that current flat through 50 °C, then derates gradually to 11 A at 70 °C. The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — numbers that tell you this breaker is sized for high-fault industrial panels, not light commercial gear. The 76.2 mm width (3 in) and 70 mm depth (2.76 in) mean it fits standard SENTRON mounting patterns — same footprint as other 3VA frame sizes — so a panel laid out for a 3VA1110 family breaker should accept this unit without re-drilling the gland plate.
