The Siemens SENTRON 3VA2110-5HN36-0HL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity hits 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA figure at 240 V means it can interrupt a fault current nearly 190 times its rated load without welding or rupturing — critical for high-fault panels near large transformers or utility feeds.
Fit and integration
Footprint is 105 mm wide by 181 mm tall by 86 mm deep — a standard 3-pole MCCB envelope that fits Siemens SENTRON mounting plates and most DIN-rail adapter kits. The 10 W maximum power loss at full load is modest; no forced ventilation required in a typical IP54 enclosure, though keep it clear of heat-sensitive components above the breaker. Line protection design (no ground-fault monitoring, no communication module) keeps this a straightforward thermal-magnetic or electronic-trip MCCB — no auxiliary power wiring beyond the shunt trip (STL) if you order that option. The built-in trip indicator and voltage trigger give visual and electrical status for PLC or annunciator inputs.
