The TM210 thermal-magnetic release handles overloads and short-circuits without external control power.
Breaking capacity — what it means for fault duty
At 240 V it breaks 75.6 kA; at 415 V, 52.5 kA; at 440 V, 32 kA; and at 500 V and 690 V it holds at 7.5 kA. For a 480 V panel with a 50 kA available fault current, this breaker covers the high-fault end at 240 V but you need to check the 440 V figure (32 kA) against your actual fault study — a common gotcha when the transformer secondary is 480 V.
Panel fit and auxiliary switch
Dimensions are 130 mm tall, 76.2 mm wide (3 in), and 70 mm deep — a standard MCCB footprint that drops into most DIN-rail or panel-mount bases without re-drilling. Power loss is 19.2 W max — account for that in a sealed enclosure thermal calc.
