The 3VA2140-6KP36-0AA0: Breaking capacity is the headline spec on this frame: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. At typical 400 V class distribution voltages, 187 kA interrupting capacity places this breaker upstream in a high-fault-current installation — think transformer secondaries or large motor control center feeders where available fault current exceeds 100 kA. The 3-pole design suits three-phase systems. Rated insulation voltage is 800 V, which covers 480 V and 600 V class systems with margin.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep. The 105 mm width is the standard 3-pole MCCB footprint for this SENTRON frame size — verify the mounting hole pattern against your existing panel layout, but the form factor is consistent across the 3VA2 family.
