Its continuous current rating Iu is 63 A at ambient temperatures up to 50 °C; above that it derates to 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C — so if your panel runs hot, you lose about 10 % of the headroom by 70 °C. The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.
Panel integration and wiring notes
The breaker measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panels. The TM220 release is fixed thermal-magnetic (no electronic adjustment), and there's no auxiliary contact or communication module on this variant — if you need remote status, you'll add the separate 3VA9608-0BB25 auxiliary trip block. The undervoltage release is built in, so verify your control voltage matches the coil rating before energizing.
