The Siemens SENTRON 3VA2110-7KQ36-0AA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, with an adjustable thermal-magnetic trip unit covering 150 A to 1 200 A. Its interrupting capacity reaches 330 kA at 240 V AC, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 3.7 kA at 690 V — the 240 V figure is the one that governs most North American panelboard applications, while the 415 V rating matters for European 400 V distribution.
The adjustable trip range (150–1 200 A) lets you set the magnetic pickup to coordinate with downstream branch breakers; the 100 A thermal element is the fixed long-time pickup, so the breaker clears sustained overloads above that level regardless of the magnetic setting.
As a SENTRON series product, it carries the usual Siemens compliance documentation (UL, CSA, IEC 60947-2, RoHS, REACH) — verify the specific certification markings on the nameplate for your jurisdiction.
