The Siemens SENTRON 3VA2010-5KP32-0AH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, designed for line protection in distribution panels and motor control centers. Its interrupting capacity reaches 187 kA at 240 V, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — a range that covers most industrial fault-current scenarios below 690 V without needing a current-limiting upstream device.
What the ratings mean for your panel
The 100 A continuous rating holds flat from 40 °C through 70 °C ambient — no derating curve to track in a warm enclosure, which simplifies panel thermal budgeting. At 86 mm deep × 105 mm wide × 181 mm tall, it fits standard MCCB footprints in Siemens SENTRON distribution boards and most third-party enclosures with DIN-rail or screw-mount provisions. The 13.5 W maximum power loss at rated load is modest enough that adjacent devices in a crowded cabinet won't see thermal crosstalk issues.
