125 A MCCB with TM210 release — selectivity and SCCR headroom
The 4-pole design handles three-phase plus neutral protection, and the 50% N-conductor protection setting means the neutral pole trips at half the phase rating — standard for distribution panels where the neutral carries only unbalanced load. Breaking capacity is the headline selector here: 75.6 kA at 240 V AC, 52.5 kA at 415 V AC, 32 kA at 440 V AC, and 11.9 kA at both 500 V and 690 V AC. For a site electrical engineer building a selective coordination study, the 415 V figure is the one that governs most European industrial panels — 52.5 kA SCCR gives headroom above typical 25–36 kA fault levels at the main distribution board. The IP40 front protection means it's enclosed in a panel — not for washdown environments, but standard for switchgear cubicles.
The continuous current holds flat at 125 A from 40 °C through 50 °C, then derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C.
