That flat curve means a panel running at 60 °C ambient still gets full 100 A capacity, which simplifies thermal budgeting in a crowded enclosure. ## MCS110 overcurrent release — fixed I²t, no trip indicator The overcurrent release is the MCS110, a fixed thermal-magnetic design with no adjustable I²t curve. The trip indicator is absent, so fault diagnosis relies on the breaker position or an external auxiliary contact — none are included (0 CO contacts for auxiliary contacts). The protection function is I (instantaneous only, no ground-fault or undervoltage release). For DC network applications, Siemens directs to the 3VA device manual. The breaker measures 75.1 mm deep, 50.8 mm wide, and 129.4 mm high — a 2-inch wide body that fits a standard DIN-rail or panel-mount cutout. Front protection is IP40, meaning tools or fingers won't contact live parts from the front, but the sides and back are not sealed against dust ingress. Maximum power loss is 12.3 W, which should be factored into enclosure ventilation if several breakers are ganged. ## Current lifecycle — no EOL notice No successor MPN is listed in the evidence. For BOM planning, the part remains in active catalog status; any future PCN would be managed through the standard Siemens obsolescence process.","metaTitle":"Siemens 3VA4110-1BB24-0AA0 SENTRON MCCB, 100 A, 2-Pole","metaDescription":"Siemens SENTRON 3VA4110-1BB24-0AA0 molded-case circuit breaker, 100 A at 40 °C, 2-pole, 415 V AC, IP40 front, UL HEAB.
