Interrupting capacity drops with system voltage: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. The 32 A rating holds steady from 40 °C to 50 °C, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C — so in a warm enclosure near the 70 °C operating limit, expect a 2 A reduction.
No separate UVR module to wire in — saves a DIN slot and reduces panel wiring.
220 kA at 240 V, which drops to 154 kA at 415 V and 121 kA at 440 V.
