Rated 160 A continuous at 40 °C, it holds that full rating through 50 °C before derating begins: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, 142 A at 70 °C (–). That thermal curve matters when the breaker shares a warm panel with drives or transformers — you don't lose headroom until the ambient climbs past 50 °C. Breaking capacity is the headline number that decides coordination: 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. That's a selectivity win for the panel designer. The TM120M overcurrent release is a thermal-magnetic type — thermal element handles overloads (inverse time), magnetic element handles short-circuits (instantaneous). This is a straightforward, field-reliable MCCB for motor branch circuits where adjustable electronic trip isn't needed.
