What this MCCB delivers
The Siemens SENTRON 3VA2110-7MN36-0DH0 is a 3-pole molded case circuit breaker rated for 100 A continuous at 40 °C through 70 °C — no derating needed across that band. Its interrupting rating hits 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 3.7 kA at 690 V. That 330 kA figure at 240 V means it can safely clear a fault on a high-capacity transformer secondary or a large motor branch without the arc flash energy escalating — the kind of SCCR that lets you avoid a series-rated cascade upstream.
Motor protection and auxiliary features
This MCCB is explicitly designed for motor protection, with phase failure detection built in. It ships with an undervoltage release (UVR) and a 2-auxiliary-switch + 1 trip-alarm-switch HQ configuration — so you get remote status of the breaker state and trip cause without adding a separate module. The trip indicator confirms the breaker opened on a fault versus manual switching. Power loss maxes at 12.5 W, which keeps panel heat manageable in a dense enclosure.
Physical fit and mounting
Dimensions: 86 mm deep, 105 mm wide, 181 mm tall. That 105 mm width is standard for a 3-pole frame in the SENTRON 3VA family — it mounts on a DIN rail or screws into a panel baseplate. The 86 mm depth leaves clearance for rear-connected busbars or cable lugs in a typical 200 mm deep enclosure.
