The Siemens 3VA2110-5MN36-0AA0 is a SENTRON molded case circuit breaker (MCCB) designed specifically for motor protection, with a rated continuous current of 100 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. Its 3-pole construction and motor protection design mean it's built for three-phase motor branch circuits, with phase failure detection built in and an adjustable trip class that lets you match the overload curve to the motor's thermal withstand: selectable between 10A, 10E, and 20E classes.
The interrupting ratings span the voltage range you'd expect in industrial distribution: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The rated insulation voltage of 800 V gives headroom for 690 V systems, and the maximum power loss of 10 W is modest for a 100 A frame — panel thermal rise stays manageable even in a crowded enclosure.
Dimensions are 105 mm wide by 181 mm high by 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises. Operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C, so it's suitable for unconditioned electrical rooms and outdoor-rated cabinets within those limits.
