The thermal element tracks load current over time; the magnetic element trips instantaneously on high faults. A trip indicator on the front confirms the breaker opened on a fault, not a manual switch-off — useful when you're tracing a nuisance trip on a paper-machine feeder. At 240 V it interrupts 220 kA; at 415 V, 154 kA; at 440 V, 121 kA; at 500 V and 690 V, 17 kA. The breaker occupies a 76.2 mm wide (3 in) footprint on the DIN rail or mounting plate, 130 mm tall and 70 mm deep. The 70 mm depth (2.76 in) leaves room for rear-connected bus bars or a shallow enclosure back wall. The auxiliary switch configuration is factory-fitted: one auxiliary contact plus one trip-alarm switch (HP type). That covers remote status feedback — breaker on/off and fault-tripped — without adding a separate accessory module.","metaTitle":"Siemens 3VA1140-6EF36-0AG0 SENTRON MCCB, 40 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1140-6EF36-0AG0 molded case circuit breaker, 3-pole, 40 A rated, TM240 release, 220 kA breaking at 240 V.
