Four poles, line-protection duty. The interrupting ratings are the headline: 187 kA at 240 V AC, 121 kA at 415 V AC, 75.6 kA at 440 V AC, and 17 kA at 500 V and 690 V AC.
At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. That's a shallow derating curve — only 9 A lost over a 30 °C rise — so it keeps its full rating in most ventilated enclosures.
What the TM210 release means for coordination
The TM210 is a thermal-magnetic release — fixed thermal pickup, fixed magnetic short-circuit pickup. That makes it a straightforward line-protection breaker for feeder circuits where you don't need selective coordination curves or remote tripping. The 100% rated N-conductor protection (4-pole, all poles protected) suits it for 3-phase + neutral systems where the neutral carries load current.
