Its breaking capacity is 220 kA at 240 V, stepping down to 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V — the high interrupt rating at 240 V makes this a strong candidate for low-voltage distribution where fault current is severe. The 125 A rating holds flat from 40 °C through 50 °C, then derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Maximum power loss is 30.6 W — factor that into enclosure heat rise if the breaker is panel-mounted alongside other heat sources. The trip indicator is present. If your circuit requires undervoltage protection for motor starters or safety disconnects, the UVR is already built in — no separate add-on needed. The 3-pole width is standard for SENTRON 3VA switchboard and distribution panel layouts — verify busbar spacing and mounting footprint against your existing panel cutout.","metaTitle":"Siemens 3VA1112-6EF36-0DH0 SENTRON MCCB, 125A, 220kA at 240V","metaDescription":"Siemens 3VA1112-6EF36-0DH0 SENTRON molded case circuit breaker, 3-pole, 125A rated, 220kA breaking at 240V.
