Breaking capacity runs 220 kA at 240 V AC, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V; those numbers cover most industrial service-entrance and feeder applications where high fault current is expected. The 158 mm height, 140 mm width, and 70 mm depth footprint fits standard SENTRON panel cutouts, so it swaps into existing 3VA family mounting without re-drilling the backplate. ## Thermal derating — what the 200 A rating really means at panel ambient Above that it steps down: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If your panel internal temperature runs above 50 °C — common in sealed enclosures or near heat sources — size the breaker one frame step up or verify the actual load current against the derated value. The TM240 release does not have a voltage-trip or undervoltage accessory, so it's a straight thermal-magnetic device with no add-on shunt or UVR coil. Auxiliary contacts are built in: one auxiliary switch plus one trip-alarm switch (HP type), which gives you a remote status signal without a separate module.","metaTitle":"Siemens 3VA1220-6EF42-0AG0 SENTRON MCCB, 200A, 4-Pole, 220kA","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0AG0 molded case circuit breaker, 200A rated, 4-pole, line protection.
