Breaking capacity reaches 187 kA at 240 V AC, stepping down through 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V — the 690 V figure is the one that governs selectivity in 480/600 V class panels.
The 160 A frame is thermally rated at 40 °C ambient; it holds 160 A through 50 °C, then derates to 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C. It ships with 2 HQ auxiliary switches for status feedback.
Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — the 105 mm width is the standard 3-pole MCCB footprint for the 3VA2 frame, so it drops into existing SENTRON mounting bases without re-drilling.
