The headline number here is the interrupting capacity: 220 kA at 240 V AC, dropping to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. The 32 A continuous rating holds flat from 40 °C up to 50 °C, then derates slightly to 30 A at 70 °C, which is a solid thermal curve for a panel that might run warm.
Auxiliaries and integration
That means you get remote status indication and the ability to trip the breaker from a remote pushbutton or a safety relay — useful for emergency-stop circuits or remote shutdown sequences. The shunt trip is a separate voltage-triggered release, so you don't need an undervoltage release module for that function. The breaker itself is 70 mm deep, 76.2 mm wide, and 130 mm tall, which is a standard SENTRON 3VA footprint for a 3-pole frame at this rating. It will fit existing 3VA panel cutouts and busbar arrangements without modification.
