32 A MCCB with 121 kA interrupting rating — line protection for high-fault panels
Its interrupting capacity hits 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that tell you it handles high available fault current without cascading upstream. At 690 V it still breaks 11.9 kA. The TM210 release is thermal-magnetic — fixed thermal curve for overload, magnetic pickup for short circuit. The 32 A rating holds flat from 40 °C to 50 °C, then derates to 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C.
The breaker measures 76.2 mm wide, 130 mm tall, 70 mm deep — standard SENTRON 3VA footprint. An undervoltage release (UVR) is built in; no separate undervoltage module needed.
