This breaker carries a 187 kA interrupting rating at 240 VAC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. The steep fall at 690 V is typical for an MCCB with a 100 A frame — the arc extinction limits at higher voltage. For a 480 V panel (common in North America), the 121 kA at 440 V is the closest published figure; for 400 V systems (IEC world), the 121 kA at 415 V applies.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint for the SENTRON 3VA2 frame. It mounts via the rear screw terminals to a DIN rail or direct panel-mount plate. The 86 mm depth leaves clearance for rear-connected busbars in a typical distribution cabinet.
