Line protection MCCB with TM210 release
Breaking capacity reaches 32 kA at 415 V AC, with higher fault-handling at lower voltages — 52.5 kA at 240 V — and derates to 13.6 kA at 440 V and 7.5 kA at 690 V. Dimensions are 70 mm deep by 76.2 mm wide by 130 mm tall, fitting the standard SENTRON 3VA mounting footprint.
Thermal derating and auxiliary configuration
The 63 A rating holds flat from 40 °C through 50 °C, then begins a gradual derating curve: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. For a panel running warm — say 55 °C internal ambient — the effective continuous current drops roughly 4 %, which matters when sizing for a continuous load near the breaker's nameplate. The shunt trip is factory-fitted as part of the order code — no field retrofit required.
