Its interrupting capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V AC, 75.6 kA at 500 V AC, and 3 kA at 690 V AC — these figures govern the available fault current the breaker can safely clear at each system voltage without upstream cascading.
Auxiliary functions and integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — the width is the critical panel cutout dimension for a 3-pole SENTRON 3VA frame; verify the mounting footprint against your existing busbar or DIN-rail adapter.
