At 415/440 V it still holds 187 kA, dropping to 121 kA at 500 V and 5 kA at 690 V.
The shunt trip (STL) allows remote tripping from a PLC or emergency-stop circuit.
Rated 63 A straight through 50 °C ambient; above that it derates — 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, 53.6 A at 70 °C. The 105 mm width, 181 mm height, and 86 mm depth match the standard 3VA2 panel cutout. Max power loss is 4 W.
It uses an ETU320 electronic overcurrent release with adjustable long-time, short-time, and instantaneous protection. No ground-fault monitoring on this variant.
