Rated insulation voltage is 800 V, and the interrupting ratings climb steeply with lower system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.
The 32 A rating holds flat from 40 °C to 50 °C — no derating needed in a warm panel — then drops only to 30.72 A at 55 °C and 28.8 A at 70 °C. That thermal curve means you can size it for 32 A of continuous load in a ventilated enclosure without padding for ambient drift. The shunt trip (STL) release is factory-integrated (order code 3VA9688-0BL33 for the trip unit itself); if you need remote trip capability, this variant has it onboard.
