The Siemens 3VA1132-5ED46-0AA0 is a SENTRON molded case circuit breaker, 4-pole, rated 32 A continuous at 40 °C with a TM210 thermal-magnetic release. The interrupting ratings climb to 187 kA at 240 V AC and 121 kA at 415 V AC, dropping to 75.6 kA at 440 V and 17 kA at 500 or 690 V.
That simplifies spec-in for a BOM line where the 32 A rating is locked, but it also means you cannot field-adjust the continuous current. The 800 V rated insulation voltage (Ui) and 690 V AC operating voltage cover most 400/480 V distribution panels with headroom for 600 V class. Current derating is minimal through the temperature range: 32 A holds from 40 °C to 50 °C, then drops only 1 A per 5 °C step to 30 A at 70 °C. Power loss is 10.6 W maximum — modest for a 4-pole 32 A MCCB, so internal enclosure temperature rise stays manageable without forced ventilation in most panel layouts.
That covers unheated warehouses and most plant-floor conditions without special derating.
