Interrupting capacity by voltage
This breaker clears faults up to 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
Current range and adjustment
The trip unit adjusts from a minimum of 189 A to a maximum of 945 A, which is the short-circuit and overload pickup range, not the continuous rating. The continuous current is fixed at 63 A by the frame and thermal elements; the 189–945 A band sets the magnetic trip level for motor-starting inrush.
It measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into the same DIN-rail or panel-mount space as other SENTRON 3VA2 breakers. The depth of 86 mm leaves room for rear busbar connections in a shallow backpanel.
Environmental limits
The 4 W maximum power loss is low enough that you don't need to derate adjacent devices in a packed panel.
