It's a 3-pole unit rated at 12.5 A continuous current at 40 °C, with a TM110M thermal-magnetic overcurrent release that gives you fixed thermal and magnetic trip settings tailored for motor starting inrush. For a panel builder, that simplifies coordination: you can land this breaker directly on a high-capacity bus without cascading selectivity concerns.
The interrupting rating drops as system voltage rises — that's normal for any MCCB, but the curve here is worth noting. At 415 V it's still 154 kA, at 440 V it's 121 kA, then it falls sharply to 7.5 kA at 500 V and holds at 7.5 kA at 690 V.
The 12.5 A rating holds flat from 40 °C to 50 °C, then begins a gentle derating: 12.1 A at 55 °C, 11.9 A at 60 °C, 11.5 A at 65 °C, and 11 A at 70 °C. That's a 12% reduction from 50 °C to 70 °C — not aggressive, but if the breaker is mounted in a sealed enclosure near a motor or drive, the 70 °C operating limit is the hard ceiling.
The 3VA1192-6MG36-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep.
