The interrupting ratings tell you where it fits: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That 121 kA at 240 V puts it squarely in high-fault panels — think large transformer secondaries or busway drops where a standard 25 kA MCCB would weld closed. Thermal derating is flat to 50 °C (32 A), then drops to 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. Comes with 3 auxiliary switches HQ (high-quality) built in — no separate aux contact block to order. This is a straight line-protection breaker; if you need those options, look at the 3VA1 variants with the appropriate release code. Latching endurance is 15,000 operations — not a switching breaker for frequent motor starts, but fine for infrequent manual isolation or backup protection. The manufacturer provides RoHS and REACH declarations, plus UL and IEC certifications as standard for the SENTRON family. Always verify the specific certification mark on the nameplate for your jurisdiction.","metaTitle":"Siemens 3VA1132-4EF32-0AD0 SENTRON MCCB, 32 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1132-4EF32-0AD0 molded case circuit breaker, 32 A, 3-pole, 121 kA at 240 V.
