The TM220 thermal-magnetic release provides inverse-time overload protection (thermal) and instantaneous short-circuit protection (magnetic), set at a fixed 10x In for the magnetic trip. Breaking capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. For a 480 V system, the 75.6 kA rating at 440 V is the closest published value; the actual SCCR at 480 V would need to be confirmed from the full UL/CSA curve, but this breaker is clearly intended for high-fault installations. Operating temperature range is -25 to 70 °C, with a derating curve above 55 °C that drops the rating from 63 A down to 58 A at 70 °C. Storage range is -40 to 80 °C.
Panel integration and dimensions
The 3VA1163-5EE36-0AC0 measures 70 mm deep, 76.2 mm wide, and 130 mm high — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. Depth of 70 mm (2.76 in) is shallow enough for most shallow-backpan enclosures, but verify clearance for the arc-chamber venting and cable bending radius.
