The interrupting capacity reaches 187 kA at 240 V AC, stepping down to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — covering most industrial distribution voltages without needing a current-limiting upstream device. An integrated undervoltage release and two HQ auxiliary switches come factory-fitted, saving panel space versus add-on modules. The universal release (UNI) design accepts both undervoltage and shunt trip coils in the same slot. Above that, it derates linearly: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Dimensions are 130 mm height, 76.2 mm width (3 inches), and 70 mm depth.","metaTitle":"Siemens 3VA1112-5EE32-0LC0 SENTRON MCCB, 125A, 3-Pole, 187kA","metaDescription":"Siemens 3VA1112-5EE32-0LC0 SENTRON molded case circuit breaker, 125A thermal rating, 3-pole, 187kA breaking at 240V.
