The interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V.
Thermal derating — when the panel runs hot
At 55 °C it derates to 24 A, at 60 °C to 23.5 A, at 65 °C to 23 A, and at 70 °C to 22.5 A. If your panel sits near a heat source or in a non-ventilated enclosure, size the load to the derated figure — not the 25 A nameplate.
Front protection is IP40.
What it protects — line protection duty
Product version is line protection — not motor protection or generator protection. The TM210 release is a thermal-magnetic type: thermal element handles overloads (inverse-time curve), magnetic element handles short-circuits (instantaneous). No phase-failure detection, no undervoltage release, no communication. It is a straightforward feeder breaker for distribution panels, sub-distribution boards, or as a main disconnect for a control cabinet.
