That flat thermal curve is unusual for an MCCB; most competitors start knocking current back at 50 °C. The interrupting ratings are tiered by system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That 86 mm depth is the critical number for shallow enclosures or gland-plate clearance — it's the dimension that runs into the back of the panel. The 140 mm width for a 4-pole frame is standard for this class; verify your existing busbar or lug spacing if you're swapping from a different manufacturer.","metaTitle":"3VA2010-5KQ42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU860, 187","metaDescription":"Siemens SENTRON 3VA2010-5KQ42-0AA0 molded case circuit breaker, 100 A rated, 4-pole, ETU860 trip unit, 187 kA at 240 V.
