That 25 A holds steady through 50 °C — only drops to 24 A at 55 °C and 23 A at 70 °C, so it handles warm panel environments without derating drama. The interrupting rating is the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and still 11.9 kA at 690 V.
Overcurrent release and protection design
The overcurrent release is a TM210 — a thermal-magnetic trip unit. Thermal element handles overloads (slow response to sustained overcurrent), magnetic element handles short-circuits (instantaneous on high fault current). It's a straight line-protection MCCB: bolted in, wired through, trips when it needs to. Power loss is 8.5 W max, which is modest for a 4-pole 25 A frame.
That's a standard MCCB footprint — fits most panel-mounted or DIN-rail adapter bases in the SENTRON family. The IP40 front means it belongs in a clean indoor panel, not a washdown zone.
