Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that tell you it handles high-fault-current scenarios like transformer secondaries or large motor control centers without cascading failure upstream. 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.
