It carries a 25 A rating at 40 °C (holds the same 25 A up to 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C) — so on a warm panel floor you still get full ampacity. The TM210 thermal-magnetic release handles overloads and short circuits, and the 121 kA breaking capacity at 240 V gives serious fault-current headroom on a 480Y/277 V or 208Y/120 V service.
The interrupting ratings cover the common industrial voltages: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
That 76.2 mm width is a standard 3-inch footprint — drops into a 3-pole MCCB slot in a SENTRON distribution panel or any DIN-rail-mounting enclosure that accepts 3-pole molded-case frames.
Insulation voltage rated at 800 V. The design is line protection (not motor protection — that would be a different release). The supplied basic switch is 3VA10254ED320AA0; auxiliary switch configuration is 4 auxiliary switches HQ. Ground-fault monitoring is not included on this variant.
