Rated 125 A continuously at 40 °C, it handles the same current up to 50 °C without derating; above that the curve drops to 114 A at 70 °C. Breaking capacity is 75.6 kA at 240 V AC and 52.5 kA at 415 V AC, which covers most low-voltage distribution fault levels in North American and IEC panels.
The 101.6 mm wide (4 in), 130 mm tall, 70 mm deep footprint fits standard panel-mounted MCCB cutouts.
75.6 kA at 240 V AC, 52.5 kA at 415 V AC, 32 kA at 440 V AC, and 11.9 kA at 500 V / 690 V AC.
