At 500 V and 690 V the rating drops to 17 kA, still sufficient for most industrial 480/600 V systems when coordinated properly. The 80 A rating holds flat from 40 °C through 50 °C, then derates gradually to 74 A at 70 °C — a thermal curve that matters when you pack breakers into a warm enclosure. The UVR drops the breaker on loss of control voltage — standard for safety circuits where a voltage dip must open the load. No ground-fault monitoring module is included; that's a separate add-on if you need it. ## Panel fit and thermal reality The 3VA1180-6EF36-0DH0 measures 76.2 mm wide, 130 mm high, and 70 mm deep — a 3-pole MCCB footprint that drops onto a standard DIN rail or mounts via the rear screw terminals. At 21.7 W maximum power loss, it dumps enough heat that adjacent breakers need spacing per the manufacturer's derating table; don't pack them tight in a sealed enclosure without airflow. The trip indicator gives a visual flag on fault — useful for panel walk-downs without opening the door.","metaTitle":"Siemens 3VA1180-6EF36-0DH0 SENTRON MCCB, 80 A, 3-Pole, 220 k","metaDescription":"Siemens 3VA1180-6EF36-0DH0 SENTRON molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 220 kA breaking capacity at 240 V.
