It's built for line protection — meaning it guards feeder or branch circuits against overload and short-circuit, not motor or generator duty. The 75.6 kA interrupting rating at 240 VAC is the headline number; at 415 V it still holds 52.5 kA, and at 690 V it's 10.5 kA. That's enough SCCR headroom for most industrial panel secondary feeds without cascading upstream breakers.
Thermal derating — the real continuous current
At 55 °C it drops to 15.36 A, at 60 °C to 15.04 A, at 65 °C to 14.72 A, and at 70 °C to 14.4 A. The TM240 release is fixed, not adjustable, so there's no dial to recover headroom.
Panel fit — footprint and aux contacts
The 3VA1196-3EF32-0AB0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep. It ships with 2 auxiliary switches (HP type) built in, which saves an add-on module slot.
