The Siemens 3VA2110-6KP32-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current, with a 3-pole configuration and an ETU850 electronic trip unit. Its breaking capacity is 242 kA at 240 V and 187 kA at 415 V and 440 V — figures that govern fault-clearing capability in low-voltage distribution. The 100 A rating holds flat across the full ambient range from 40 °C to 70 °C (–), so no derating curve to calculate for typical enclosure temperatures.
The 3VA2110-6KP32-0AA0 measures 86 mm deep, 105 mm wide, and 181 mm high (–). The 105 mm width is standard for a 3-pole frame in this class — expect it to occupy three 35 mm module spaces on a DIN rail. No undervoltage release or shunt trip is factory-installed, so add an external module if those functions are needed for emergency stop or undervoltage protection schemes.
Coordination and selectivity notes
The ETU850 electronic trip unit supports adjustable I²t curves and short-time delay settings, which are essential for selective coordination downstream of a larger feeder breaker. The 800 V rated insulation voltage allows use in 480/277 V and 600 V systems with margin. The communication function enables integration with energy management systems via optional PROFIBUS or PROFINET modules — the base breaker is ready for it.
