Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V, so it handles high-fault industrial distribution panels without cascading upstream.
At 55 °C it's 241 A, at 60 °C it's 232 A, at 65 °C it's 222 A, and at 70 °C it's 213 A. The IP40 front protection keeps dust and small tools out of the mechanism; the body dimensions (181 mm height, 105 mm width, 86 mm depth) fit standard SENTRON 3VA panel cutouts and busbar systems.
Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V.
It uses the ETU350 electronic trip unit, configured for line protection without undervoltage release or communication functions.
