A built-in trip indicator gives a local visual of the breaker state — saves the service tech a meter check on a tripped circuit.
Ratings that matter for fit
The 32 A rating holds flat from 40 °C to 50 °C (–), then derates to 30 A at 70 °C. Interrupting capacity drops from 121 kA at 240 V to 75.6 kA at 415 V and 52.5 kA at 440 V — still high enough for most secondary distribution, but verify the available fault current at your service voltage before committing the BOM line.
The 3VA1132-4EF36-0HH0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most Siemens SENTRON panelboards and distribution blocks without re-drilling the gland plate.
