Just the breaker, the trip curve, and the interrupting capacity. Interrupting capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at 500 V. That's high-rupture-capacity territory — enough to handle large transformer-fed faults or tie into a high-fault utility feed without cascading upstream. Thermal derating is flat from 40 °C to 50 °C (40 A), then drops to 39 A at 55–60 °C, 38 A at 65 °C, and 37 A at 70 °C. If the panel runs hot, you lose 3 A off the top — plan the load margin accordingly. Panel footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB slot on a DIN rail or direct-mount plate. Rated insulation voltage 800 V, max operating voltage 690 V AC, 500 V DC. Power loss is 11 W maximum.","metaTitle":"Siemens 3VM1140-5ED32-0AA0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VM1140-5ED32-0AA0 molded case circuit breaker, 40 A, 3-pole, TM210 release, 187 kA at 240 V.
