The Siemens SENTRON 3VA2110-5HN36-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels. Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415/440 V, and 75.6 kA at 500 V — figures that define its fault-clearing capability for high-fault industrial feeds. The 86 mm depth and 105 mm width fit standard MCCB mounting footprints, so it swaps into existing SENTRON or third-party panel layouts without re-drilling the gland plate.
Ratings and what they mean for the panel
The 100 A rating holds flat across 40 °C to 70 °C ambient — no derating curve to chase. That means the breaker delivers its full continuous current in a warm enclosure without a size-up. The 187 kA at 240 V is the short-circuit current rating (SCCR) the breaker can safely interrupt; at 690 V the capacity drops to 3.7 kA, so verify the available fault current at the installation point if running higher line voltages. Insulation voltage rated 800 V gives headroom for 480/600 V systems.
Integration notes
Mounts on a DIN rail or panel-mount plate; the 105 mm width occupies three pole spaces in a standard MCCB lineup. The supplied basic switch (order code 3VA21105HN360AA0) and two auxiliary switches (HP type) are factory-fitted — no field assembly of the aux contact block. No undervoltage release, no ground-fault monitoring, and no communication module on this variant, so keep a separate shunt trip or UVR if the circuit requires one.
