The 3VA1132-5EF32-0AF0: Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and still 17 kA at 690 V. That's a high-interrupting rating that gives you headroom for high-fault panels without cascading upstream breakers. The TM240 release means the thermal trip is fixed at 32 A up to 50 °C ambient; above that, derate linearly to 28.8 A at 70 °C. If your panel runs hot, that's the number to size against, not the 32 A label.
Panel fit and wiring
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB envelope for DIN-rail or screw-mount panel integration. Front IP40 keeps out tools and dust; fine for a clean indoor panel. Comes with one auxiliary switch and one trip alarm switch (HQ type) built in. That covers remote status and trip indication without adding a separate module.
Lifecycle and compliance
Rated insulation voltage Ui is 800 V, storage range -40 to 80 °C, operating -25 to 70 °C. The 800 V Ui tells you it's rated for 690 V systems with margin, consistent with the 690 V breaking capacity rating.
