The TM220 thermal-magnetic release handles overload and short-circuit curves without a separate trip unit — set it and forget it for fixed-threshold distribution panels. Interrupting capacity hits 220 kA at 240 V, dropping to 154 kA at 415 V and 121 kA at 440 V — still well above typical utility fault levels for most industrial services. At 690 V it holds 17 kA, so it's usable on 480Y/277 V or 600 V delta systems within that ceiling. The 3-pole footprint measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard SENTRON 3VA frame that drops into existing 3VA panel cutouts without re-drilling.
Rated 100 A from 40 °C through 50 °C; above that it derates linearly to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. The storage limits govern handling and warehousing, not running conditions.
