The interrupting ratings tell you where this breaker can live on the fault-current map: 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.
The TM220 overcurrent release is a thermal-magnetic trip — the thermal element handles overloads (slow response to sustained overcurrent), the magnetic element handles short circuits (instantaneous). It's the standard release for general distribution; no electronic adjustment, no communication module. Temperature derating is minimal up to 50 °C — the breaker holds full 25 A rating. That means in a hot panel near the top of an enclosure you still get 92% of rated current, which is better than many MCCBs that start derating at 40 °C.
Integration notes
Dimensions are 101.6 mm wide (4 inches), 130 mm tall, 70 mm deep — standard 4-pole MCCB footprint for the 3VA frame size.
