It carries a 187 kA breaking capacity at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — figures that tell you it can interrupt severe fault currents on the line side of a distribution panel without upstream coordination issues. Rated insulation voltage Ui is 800 V, and the breaker holds its full 63 A rating up to 50 °C ambient; above that it derates gradually to 56.7 A at 70 °C. The 15 000-cycle latching endurance is typical for a panelboard main or feeder breaker — not a daily-switch duty cycle.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard SENTRON 3VA frame that mounts on a DIN rail or screws into a panel backplate.
