The Siemens SENTRON 3VA1132-4EF32-0BH0 is a 3-pole molded case circuit breaker rated for 32 A continuous current at 40 °C ambient, with no derating needed up to 50 °C — at 55 °C it still holds 31 A, and at 70 °C it holds 30 A, so in a warm panel or next to other heat sources you lose only 2 A across the full operating range. Breaking capacity is 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — that covers most industrial distribution voltages and means this breaker can interrupt a high-fault bolted short without upstream coordination issues, provided the available fault current at the panel doesn't exceed those values.
Auxiliary and release configuration
At 76.2 mm wide, 130 mm tall, and 70 mm deep, this 3-pole MCCB fits standard SENTRON mounting footprints — the width is exactly 3 inches, which matches the common DIN-rail or panel-mount cutout for three-pole breakers in this class, so a panel laid out for a 3VA1 frame will accept this unit without re-drilling.
