The rated insulation voltage is 800 V, and the interrupting ratings span 187 kA at 240 V down to 17 kA at 690 V, giving the selectivity headroom needed for high-fault-capacity installations.
Breaking capacity and thermal derating
The interrupting capacity drops with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. The continuous current rating holds at 200 A from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C — the full thermal curve is on the nameplate, so panel builders can size for elevated ambient without guessing.
The case measures 70 mm deep, 140 mm wide, and 158 mm high.
Environmental and approvals
The 3VA series carries UL, CSA, and IEC certifications per the SENTRON platform.
