Breaking capacity and selectivity
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. The ETU850 electronic trip unit provides adjustable overload and short-circuit protection curves, with communication capability for integration into a power monitoring or selective coordination scheme. Rated insulation voltage is 800 V, which covers 480 V and 600 V class systems with margin.
Physical fit and panel integration
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. Front protection is IP40, suitable for enclosed panel mounting where no water ingress is expected.
