63 A MCCB with flat thermal derating to 70 °C
Its interrupting capacity hits 121 kA at 415 V and 187 kA at 240 V, dropping to 3.7 kA at 690 V — so on a 400 V distribution panel it clears high fault currents without cascading upstream.
Built-in communication and auxiliary switch complement
This breaker ships with a communication function onboard, so it can report status to a BMS or PLC without an add-on module. A shunt trip release (STL) is included for remote or emergency tripping. That's a lot of signaling packed into the standard 105 mm wide footprint — saves panel space versus adding external relay blocks.
Dimensions are 86 mm deep, 105 mm wide, 181 mm tall — standard SENTRON 3VA footprint for a 3-pole frame.
