SENTRON 3VA2010-5KP32-0AC0 — 100 A MCCB with Communication for Line Protection
The part carries a communication function, so it can report status or trip events back to a PLC or BMS over a fieldbus gateway, which saves a maintenance electrician from walking the panel line after every fault.
Interrupting Capacity and Selectivity Planning
The 3VA2010-5KP32-0AC0 delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That steep derating above 500 V is normal for MCCBs in this frame size — at 690 V the internal arc energy limits the break. For a 480 V panel (common in North America), the 75.6 kA SCCR at 500 V gives headroom above typical 65 kA or 100 kA available fault currents. When coordinating with downstream breakers, the 100 A continuous rating and the communication output let you map trip curves in software rather than guessing from a table.
Power dissipation is 13.5 W maximum.
Insulation voltage is rated at 800 V.
