The shunt trip lets a remote signal (emergency stop, fire alarm, PLC output) force the breaker open; the aux switches report position back to the control system. The interrupting ratings drop as voltage climbs: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. That 17 kA floor at 690 V is still respectable for most industrial secondary distribution — you'd only need a higher-rated upstream fuse if your available fault current exceeds that. The 40 A continuous rating holds steady from 40 °C to 50 °C, then derates to 37 A at 70 °C. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for a 40 A frame.","metaTitle":"Siemens 3VA1140-6EF32-0JC0 SENTRON MCCB, 40 A, 3-Pole, 220 k","metaDescription":"Siemens 3VA1140-6EF32-0JC0 SENTRON molded case circuit breaker, 40 A, 3-pole, 220 kA interrupting at 240 V.
