Ratings That Matter for Panel Fit
The 3VA1132-3EF32-0AH0: The 32 A rating holds flat from 40 °C through 50 °C — no derating needed in a warm enclosure until you cross 55 °C, where it drops to 30.72 A, then 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. That thermal curve is the one to check if this breaker sits near transformers or drives that push internal panel ambient above 50 °C. Mechanical endurance is listed at 15,000 operations — that's a solid number for a panel main or feeder breaker that cycles a few times a year, not a daily-switched disconnect.
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — that's a standard 3-pole MCCB envelope that drops into most DIN-rail or panel-mount SENTRON bases without re-drilling.
This is a current-production part — no last-time-buy window, no scavenging required.
