It carries a TM210 thermal-magnetic release, so the thermal element handles sustained overloads and the magnetic element clears high-fault events fast. Rated 32 A continuous at 40 °C ambient, with no derating needed up to 50 °C — still 32 A at 50 °C — then drops to 31 A at 55 °C and 30 A at 70 °C. That thermal stability is useful in a crowded enclosure where ambient heat builds. Breaking capacity is the headline number for an MCCB: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
If you need those options, you'd step to a different suffix.
That simplifies ordering but means if your load draws 30 A continuous in a 55 °C panel, the breaker still holds at 31 A, so no nuisance tripping from ambient heat alone. At 415 V, the 32 kA interrupting rating covers most industrial 400 V distribution boards where the transformer impedance keeps fault levels under that threshold. Power loss is listed at 10.6 W maximum — that's the heat dissipated inside the enclosure at rated current. In a sealed panel with multiple breakers, that number feeds into the thermal budget for the cabinet cooling calculation.
