The breaking capacity tells you where it safely interrupts a fault: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 121 kA at 240 V is the standout — it handles high-fault-current service-entrance or sub-feed applications on 240 V delta or 277/480 Y systems where the available fault current is stiff. The TM220 overcurrent release is a thermal-magnetic trip unit — thermal for overload protection, magnetic for short-circuit. It's a straightforward line-protection breaker: mount it, land the conductors, and it clears faults within its curve. The 3VA1180-4EE46-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole MCCB that fits standard Siemens SENTRON mounting bases. Maximum power dissipation is 19.2 W at rated load. In a multi-breaker panel, that heat adds up — account for it in your thermal budget, especially if the enclosure is sealed and the ambient is already pushing 50 °C.","metaTitle":"Siemens 3VA1180-4EE46-0AA0 SENTRON MCCB, 80A, 4P, 121kA at 2","metaDescription":"Siemens SENTRON 3VA1180-4EE46-0AA0 molded case circuit breaker, 80A rated, 4-pole, TM220 trip unit.
