It carries a continuous current rating of 100 A at 40 °C, with negligible derating up to 50 °C — still 100 A — then dropping to 98 A at 55 °C and 91 A at 70 °C, so it holds its full rating in most ventilated enclosures without a derate calculation.
The interrupting rating varies sharply with line voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Dimensions are 101.6 mm wide, 130 mm high, and 70 mm deep — a 4-inch wide footprint that matches the SENTRON 3VA family mounting pattern. It bolts into a standard MCCB panel cutout; no DIN-rail adapter is needed. Maximum power dissipation is 27.5 W, so adjacent devices in a sealed enclosure need that heat accounted for in the thermal budget.
