The Siemens SENTRON 3VA2110-5JP32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling.
This MCCB delivers 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 steep drop at 690 V is typical for this frame size — the internal arc energy scales with voltage, and the 3.7 kA figure means it is not the right choice for high-fault 690 V feeders unless the available fault current is below that threshold.
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep.
The 100 A continuous rating is confirmed at every 5 °C increment from 40 °C to 70 °C — no thermal derating curve to apply in a warm enclosure. The insulation voltage is rated 800 V, which covers 480/277 V and 600 V systems with margin. The shunt trip (STL) allows remote tripping via a control signal; the communication function supports integration with building management or SCADA systems for status and alarm monitoring.
