The TM210 thermal-magnetic release handles overload and short-circuit curves for feeder and distribution circuits in industrial panels. Breaking capacity reaches 220 kA at 240 V AC, dropping to 154 kA at 415 V and 121 kA at 440 V — figures that match high-fault installations like transformer secondaries or large motor control centers.
Above that, derating begins: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm tall — a 4-pole footprint that fits standard Siemens SENTRON panelboards and DIN-rail adapters.
