The TM240 thermal-magnetic release handles the overload curve, and the integrated undervoltage release (UVR) trips the breaker if control power drops, which is a common requirement for safety circuits or emergency-stop chains where loss of control voltage must open the main feeder. What sets this MCCB apart is the interrupting capacity: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V.
Thermal derating and ambient limits
At 55 °C it derates to 76.8 A, at 60 °C to 75.2 A, and at 70 °C to 72 A.
The 3VA1180-6EF36-0BA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep.
The mechanical endurance is rated at 15 000 operations — that's typical for a distribution MCCB; it's not a switching device for frequent motor starts.
