It is a 3-pole, line-protection design with a shunt trip (STL) release and an auxiliary switch block carrying 2 auxiliary switches plus 1 trip alarm switch (HQ). The interrupting capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. ## Panel fit and physical integration Dimensions are 105 mm wide by 181 mm tall by 86 mm deep. The 100 A rating is flat across the ambient range — no thermal derating curve to calculate. That simplifies panel design: if your load is 100 A or less and the ambient stays under 70 °C, this breaker holds. The 187 kA at 240 V is the SCCR (short-circuit current rating) at that voltage; it means the breaker can safely interrupt a fault up to 187 kA without catastrophic failure. At 690 V the rating drops to 3.7 kA, so if your system runs 690 V with high fault current, this is not the right breaker. Power loss is 10 W maximum — relevant for thermal management in a sealed enclosure.","metaTitle":"Siemens 3VA2110-5HN32-0JH0 SENTRON MCCB, 100 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2110-5HN32-0JH0 molded case circuit breaker, 100 A continuous, 187 kA breaking at 240 V.
