The 3VA1140-6GF42-0AA0: The TM240 thermal-magnetic release provides overload protection adjustable Ir=28 A...40 A and short-circuit protection Ii=5...10×In, meaning the magnetic trip threshold can be set between 200 A and 400 A to coordinate with downstream branch breakers.
Maximum power loss is 10.8 W at rated current, which is low enough that forced ventilation is not required in a typical IP54 steel enclosure with natural convection.
The 415 V rating (70 kA for this H-class frame) is the typical benchmark for IEC distribution panels.
