Breaking capacity is the headline here: 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. Thermal derating is gradual: holds 125 A up to 50 °C, then drops to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. The IP40 front protection means it's fine for indoor panel use but not washdown zones.
Maximum power loss is 28.1 W — factor that into your panel thermal budget if you're stacking several breakers in a confined enclosure. The adjustable li max (short-circuit release) goes to 1250 A. The TM220 release is fixed thermal, adjustable magnetic — typical for general-purpose feeder protection.
Optional motor drive available (product extension) for remote trip or reset — order separately if you need that. No communication function onboard, so no Modbus or PROFIBUS integration without an external module. N-conductor protection is 100% — the neutral pole is fully rated, not reduced. That matters for 4-wire systems where the neutral carries phase imbalance current.
