The TM210 designation means the thermal (overload) element is fixed at 63 A — no adjustable thermal dial — and the magnetic (short-circuit) pickup is fixed at 10× In, or 630 A. This is a line-protection design, not a motor-protection breaker; it is sized for feeder or distribution circuits where the load current is stable and the trip curve does not need to accommodate motor inrush. The interrupting ratings span the common industrial voltages: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Thermal derating is published across the full operating range: the breaker carries 63 A continuously up to 50 °C ambient, then steps down to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C.
Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. The 101.6 mm width (4 inches) is the standard footprint for a 4-pole 63 A frame in the 3VA1 series; it occupies four 25 mm module spaces on a DIN rail if the breaker is rail-mounted, though the 3VA1 can also be screw-mounted on a mounting plate.
