The Siemens SENTRON 3VA2110-5HK32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C through 70 °C — no derating across that ambient span, which simplifies panel design in warm enclosures. The interrupting ratings are 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 — figures that cover most industrial service-entrance and feeder applications.
No undervoltage release (cite:), no ground-fault monitoring (cite:), and no communication function (cite:) are built in — this is a base line-protection breaker with the ETU340 trip unit as the only adjustable element.
