At 70 °C it still holds 150 A — useful when the breaker shares a crowded enclosure with other heat sources. The TM210 thermal-magnetic overcurrent release handles the time-current curve; no undervoltage or ground-fault trip modules are integrated on this variant. Interrupting capacity hits 75.6 kA at 240 V AC and 52.5 kA at 415 V AC — enough for most industrial service-entrance or feeder duty where the available fault current is known. Front-face protection is IP40, so it keeps tools and dust out of the mechanism but is not sealed against hose-down.
Thermal performance and panel integration
Above that the thermal curve steps down: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. The storage ceiling exceeds the operating ceiling — that limit governs handling during transport and warehouse idle, not running conditions.
