The integrated shunt trip (STL) auxiliary release allows remote tripping via a separate control signal — useful for emergency-stop or interlock circuits where the breaker must open on command independent of overcurrent conditions. Breaking capacity defines where this MCCB can safely interrupt a fault. At 240 V it clears 75.6 kA; at 415 V, 52.5 kA; at 440 V, 32 kA; and at both 500 V and 690 V, 11.9 kA. These are the maximum prospective short-circuit currents the breaker can interrupt at each voltage — critical for coordination studies and ensuring the SCCR of the downstream panel is not exceeded. The 80 A rating holds from 40 °C through 50 °C, then derates gradually: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard Siemens SENTRON mounting footprints and accepts busbar or cable connections typical of 3-pole distribution blocks. No trip indicator is fitted; the voltage trigger (shunt trip) is present as specified by the order code suffix.","metaTitle":"Siemens 3VA1180-3EF32-0HA0 SENTRON MCCB, 80 A, 3-Pole, Shunt","metaDescription":"Siemens 3VA1180-3EF32-0HA0 SENTRON molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 70 mm depth, 75.6 kA at 240 V.
