SENTRON 3VA2010-5KP32-0AC0 — 100 A MCCB with Communication for Line Protection
The Siemens SENTRON 3VA2010-5KP32-0AC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in industrial distribution panels. Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415 V — enough to handle high-fault utility feeds without cascading upstream. 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.
Physical Fit and Panel Integration
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep. Power dissipation is 13.5 W maximum.
Environmental and Compliance
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Insulation voltage is rated at 800 V. The breaker is designed for line protection with no undervoltage release or ground-fault monitoring.
