The Siemens SENTRON 3VA2110-5MN36-0HC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, holding that rating flat from 40 °C through 70 °C ambient — no derating needed in a warm enclosure. It's designed specifically for motor protection, with integrated phase failure detection and a shunt trip (STL) auxiliary release for remote tripping.
Interrupting capacity and selectivity
Interrupting capacity is 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA at 240 V is high for a 100 A frame — it gives you headroom for high-fault panels where the upstream transformer is close. The steep drop at 690 V (3.7 kA) means this breaker is not your choice for 690 V motor circuits with substantial fault current; you'd step to a higher interrupting-rated frame.
Auxiliaries and releases
Comes fitted with 2 auxiliary switches (HQ type) and a shunt trip release. The shunt trip lets a safety PLC or E-stop circuit drop the breaker remotely — common for emergency-off zones or interlocked machine guards. No undervoltage release fitted, no ground-fault monitoring, no communication module on this variant.
Physical fit
Dimensions: 105 mm wide, 181 mm high, 86 mm deep. That 105 mm width is the standard 3-pole MCCB footprint for this SENTRON frame size — it fits the same panel cutouts and DIN-rail adapters as other 3VA2 breakers. No trip indicator on the front face; you'll rely on the auxiliary switch status or the handle position.
