For a 400 V distribution board, the 121 kA figure is well above typical utility fault levels (often 25–50 kA), so this breaker gives generous margin. At 690 V, the 3.7 kA limit means it's not suitable for high-fault industrial 690 V mains; you'd need a larger frame or a current-limiting design. ## Thermal Performance — Flat Derating to 70 °C That's unusual for an MCCB; many competitors start derating above 40 °C. The flat thermal curve simplifies panel design: you don't have to oversize the breaker for a warm enclosure or derate for a hot machine room. ## Panel Integration — Dimensions and Mounting Dimensions: 181 mm height, 140 mm width, 86 mm depth. Depth of 86 mm means it clears most standard enclosure backplates without a sub-panel. Mounting is via screw-clamp to the backplate; no DIN rail for this frame size. ## Trip Unit and Adjustment Range The trip unit is adjustable from 150 A minimum to 1 200 A maximum — that is the magnetic/instantaneous pickup range, not the continuous current. The continuous rating is fixed at 100 A.","metaTitle":"Siemens 3VA2110-5KQ42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2110-5KQ42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, 187 kA breaking at 240 V.
