The 3VA1132-4GF42-0AA0: Breaking capacity is the headline here: 121 kA at 240 VAC, dropping to 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 V and 690 VAC. That's a high-interrupting rating for a 32 A frame — it handles fault currents at the service entrance or near large transformers without cascading upstream.
Thermal derating and panel fit
The 32 A rating holds solid up to 50 °C ambient; above that it derates to 31 A at 55–60 °C and 30 A at 65–70 °C. If the panel runs hot — near a drive cabinet or in a non-climate-controlled enclosure — factor in the 1 A drop per 5 °C above 50 °C. The TM240 release is a fixed thermal-magnetic, not electronic, so there's no adjustment dial; the trip curve is set at the factory. Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep. IP40 on the front.
