Its TM240 thermal-magnetic release provides overload and short-circuit protection in a single unit, sized for main feeders or large sub-distribution in industrial switchboards. ## Breaking capacity and thermal derating — what the numbers mean for your panel Breaking capacity is the fault current the breaker can safely interrupt without welding or rupturing. At 240 V this MCCB clears 220 kA; at 415 V it clears 154 kA; at 440 V it clears 36 kA; at 690 V it clears 17 kA. That 220 kA figure at 240 V puts it in the high-interrupting class — suitable for transformer secondaries or bus-tie positions where available fault current is high. The 200 A rating holds steady from 40 °C up to 50 °C, then derates linearly to 176 A at 70 °C. If the panel ambient runs above 50 °C, size the load accordingly. ## Physical fit and auxiliary contacts The breaker measures 140 mm wide, 158 mm high, and 70 mm deep. It ships with four auxiliary switches (HQ type) pre-installed — no separate add-on module needed for status feedback to a PLC or SCADA system. The front face carries an IP40 rating, meaning protection against tools and small wires, but not against water ingress; mount it inside a closed panel.","metaTitle":"Siemens 3VA1220-6EF42-0AE0 SENTRON MCCB, 200 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0AE0 molded case circuit breaker, 200 A rated continuous current, 4-pole, 220 kA breaking capacity at 240 V.
