Its interrupting capacity reaches 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V — the figure that governs the SCCR of the downstream panel. The adjustable Ir tracks up to the full 63 A rating, so you set the overload threshold to the actual load without oversizing the breaker frame.
In a sealed, uncooled enclosure the 17.3 W maximum power loss adds to the internal temperature rise — account for that when sizing the cabinet or the breaker will trip early on a warm day.
Rated insulation voltage Ui is 690 V, and the maximum DC operational voltage is 500 V. Mechanical endurance is rated at 12,000 operations. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth.
