It holds that rating flat from 40 °C through 50 °C; above 50 °C the thermal curve begins to derate, dropping to 28.8 A by 70 °C. Breaking capacity reaches 121 kA at 240 VAC, 75.6 kA at 415 VAC, and 52.5 kA at 440 VAC — numbers that tell you it is sized for high-fault panels where a standard MCB would weld shut. The TM210 thermal-magnetic release handles the overcurrent trip, and an undervoltage release (UVR) is built in. Two auxiliary switches (HQ type) ride on the side, so you get a status signal back to the PLC without adding a separate contact block. Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — standard three-pole MCCB width for a 32 A frame.
