It's a 3-pole unit, rated 32 A continuous at 40 °C, with an interrupting capacity that climbs to 52.5 kA at 240 V and still holds 7.5 kA at 690 V. That spread tells you it's sized for industrial feeders where fault current varies by voltage level, not just a light commercial panel. The built-in undervoltage release (UVR) drops the breaker if control voltage falls below the dropout threshold — a common requirement for safety disconnects on machine tools or conveyors where loss of control power should kill the load. The auxiliary switch complement (2 aux + 1 trip alarm HQ) gives the PLC or BMS a status feedback path without adding a separate accessory.
Above that it derates in 1 A steps: 31 A at 55 °C and 60 °C, then 30 A at 65 °C and 70 °C.
