That full-load current holds through 50 °C — at 55 °C it steps down to 243 A, 237 A at 60 °C, and 230 A at 65 °C. The TM240 thermal-magnetic overcurrent release is factory-set for this frame. Breaking capacity is substantial: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. If you're protecting a feeder or a large motor branch on a high-fault panel, this breaker handles the interrupt without cascading upstream.
Mounting and fit
The 3VA1225-6EF42-0AD0 occupies 140 mm width, 158 mm height, and 70 mm depth — a 4-pole frame that fits standard SENTRON panel cutouts. At 57 W maximum power loss, factor the heat into your enclosure ventilation calculation, especially if the breaker is grouped with other high-current devices.
