Above that, it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. Maximum power loss is 50.5 W, which matters for ventilation planning in a sealed gland plate.
Interrupting capacity by voltage
The 3VA2225-5HL42-0DC0 delivers 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. At 415 V, the 121 kA figure covers high-fault utility feeds common in European and Asian plants.
Verify the gland plate knockout pattern against the 86 mm projection; some shallow enclosures need a spacer bracket.
