Integration and panel fit
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB occupies a standard 3-pole molded-case footprint. Panel builders can plan for the same gland-plate cutout and DIN-rail or screw-mount pattern as other SENTRON 3VA frame breakers.
Thermal derating and ambient range
Rated current holds at 32 A from 40 °C up to 50 °C, then drops to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. The gap between storage and operating limits means the breaker can be warehoused in unconditioned space but must be within the narrower operating band when energized.
