It carries a 121 kA breaking capacity at 240 VAC, tapering to 75.6 kA at 415 V and 52.5 kA at 440 V, with 11.9 kA available at both 500 V and 690 V — meaning it handles high fault currents on the low-voltage side of a transformer, but the interrupting rating drops sharply above 500 V, so verify the available fault current at your system voltage before specifying. The TM210 thermal-magnetic release provides fixed overload and short-circuit protection without adjustable trip settings — a straightforward choice for standard feeder circuits where you don't need the tuning flexibility of an electronic trip unit. Mounts on a DIN rail or panel base with a 76.2 mm width (3 in) and 70 mm depth (2.76 in), taking three pole spaces in a standard distribution board.
Current Derating and Thermal Performance
Rated 50 A from 40 °C through 50 °C ambient, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.
