At 70 mm deep and 76.2 mm wide, it fits the 3VA family footprint; the 130 mm height clears most distribution board gutters without a shroud.
Breaking capacity — where this MCCB clears faults
The interrupting ratings span the common industrial voltages: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.
Above that, the TM220 release begins to thermally limit: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. The latching endurance is 15 000 cycles — not a daily-switch duty, but fine for infrequent isolation or backup protection.
