The interrupting rating drops as voltage rises: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V.
Current rating holds flat at 63 A from 40 °C through 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Maximum power loss is 19.8 W — useful to know for enclosure heat calculations when the panel is tightly packed.
Built-in auxiliary and release options
At 130 mm high, 76.2 mm wide, and 70 mm deep, this 3-pole breaker fits the standard SENTRON 3VA mounting footprint.
