The interrupting ratings speak to its fault-clearing capacity: 121 kA at 240 V AC, 76 kA at 415 V and 440 V, and 53 kA at 500 V — figures that determine whether this breaker holds its SCCR in a given fault-current study. Insulation voltage is 800 V. The 184 mm width and 248 mm height fit the standard SENTRON 3VM frame footprint. Depth is 110 mm. Panel builders should verify the mounting cutout and bus-bar spacing against the existing switchgear layout — the 4-pole form factor is wider than a 3-pole equivalent, and the TM210 release occupies the same physical envelope as other 3VM releases.
Maximum power loss is 193 W at rated current. That is the heat the breaker dumps into the enclosure — relevant for thermal management in a sealed cabinet.
