The TM240 thermal-magnetic release handles overload and short-circuit trip curves — the 240 frame size means the trip unit is matched to this 63 A rating, not a higher-tap adjustable unit. Breaking capacity is 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V, which gives solid headroom for high-fault commercial or light industrial service where the available fault current is known to be substantial. That is a common requirement for safety circuits where a loss of control power must open the main breaker to prevent automatic restart. The UVR is factory-fitted; no field kit to install.
Above that, derating is gradual: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Maximum power loss is 19.8 W, which is low enough that side-by-side mounting in a standard distribution panel is fine as long as natural convection is not blocked. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole footprint that fits standard Siemens 3VA panelboard and enclosure cutouts.
