100 A MCCB with 187 kA interrupting capacity — current-production SENTRON
The Siemens SENTRON 3VA2010-5HN32-0CH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C through 70 °C, with no derating across that ambient span — per the datasheet, the 100 A rating holds flat from 40 °C to 70 °C. Interrupting capacity reaches 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 — these are the fault-clearing limits the breaker can safely interrupt without upstream cascade. Designed for line protection (feeder duty) per the product designation, with an integrated undervoltage release and a factory-fitted auxiliary switch block carrying 2 auxiliary switches plus 1 trip alarm switch HQ.
Physical fit and panel integration
Dimensions: 181 mm height, 105 mm width, 86 mm depth — mounts on a standard DIN rail or panel-mount footprint typical of SENTRON 3VA frame sizes. Maximum power loss is 16 W at rated load, which governs the enclosure ventilation requirement if multiple breakers are ganged in a sealed panel.
Environmental and storage limits
Operating ambient range: -25 °C to 70 °C. Storage range: -40 °C to 80 °C — the storage limit governs handling during transport and warehouse hold, not running conditions.
