Siemens 3VA2110-7MS36-0AC0 — SENTRON MCCB, 100 A, Starter Protection
The Siemens 3VA2110-7MS36-0AC0 is a SENTRON molded case circuit breaker (MCCB) designed specifically for starter protection — meaning it's sized and coordinated to protect motor starters and their associated control circuits, not just branch feeders. Rated 100 A continuous current across the full ambient temperature range from 40 °C through 70 °C, so no derating curve to chase for typical panel conditions. Three-pole construction, with a breaking capacity of 330 kA at 240 V and 242 kA at 415 V / 440 V, dropping to 187 kA at 500 V and 3.7 kA at 690 V — the 690 V figure is the limit for this frame size at that voltage, so verify the available fault current at the point of installation if running 690 V systems.
Physical Fit and Panel Integration
Dimensions: 181 mm height, 105 mm width, 86 mm depth. The 86 mm depth is the dimension that matters for enclosure depth clearance — standard 200 mm deep enclosures accommodate this without issue. Width of 105 mm is the DIN-rail footprint for a 3-pole frame in this SENTRON series; verify the adjacent device spacing per IEC 60947-2 for heat dissipation, though the 10 W maximum power loss at rated load is modest for this class.
Configuration and Auxiliaries
Supplied with the basic switch variant 3VA21107MS360AA0. Includes 2 auxiliary switches (HQ type) factory-fitted — no separate purchase needed for status feedback to a PLC or indication lamp. No undervoltage release, no shunt trip, no communication module, no ground-fault monitoring on this variant. Operating temperature range -25 °C to +70 °C; storage range -40 °C to +80 °C.
