The Siemens SENTRON 3VA2010-5HN36-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a 187 kA interrupting capacity at 240 VAC. It's built for line protection in distribution panels and switchgear, carrying an undervoltage release (UVR) as the auxiliary release — meaning it trips automatically if the control voltage drops, which is standard for motor control centers and safety disconnects where you need loss-of-voltage protection.
Breaking capacity and selectivity
The interrupting rating drops as system voltage climbs: 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V. That 3 kA at 690 V is the number to watch if you're feeding a 690 V drive — it's still adequate for most downstream faults but confirms this MCCB is primarily sized for 240–500 V distribution where the high fault current matters.
Thermal performance and panel fit
Rated continuous current holds at 100 A from 40 °C through 70 °C ambient — no derating needed up to that ceiling. Power loss maxes at 16 W, which is modest for a 100 A frame; ventilation in a standard enclosure handles it. Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — fits a standard 3-pole MCCB footprint on the DIN rail or panel-mount baseplate.
