Its breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — meaning it safely interrupts fault currents up to those levels without upstream cascading, critical for high-fault installations like transformer secondaries or large motor control centers.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — the 105 mm width (4.13 in) is the standard 3-pole MCCB footprint for this class, so it fits existing SENTRON 3VA panel cutouts and busbar systems without rework.
