For a panel builder, the 70 °C derated figure matters if the breaker sits next to high-heat devices like contactors or drives. The interrupting capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. The 3VA1220-4EF32-0DH0 measures 70 mm deep, 105 mm wide, and 158 mm tall (–). The depth of 70 mm means it clears most shallow enclosures, but check gland-plate clearance if the panel is under 200 mm deep. The trip indicator is present, so you get a visible flag on the front when it has tripped. This is a line-protection MCCB — it protects cables and busbars from overloads and short circuits in a distribution board or main switchboard. It is not a motor-protection breaker (no thermal-magnetic curve tuned for motor inrush), so use it for feeder and distribution circuits. The 200 A frame size suits sub-distribution to smaller panels or large branch circuits. Power loss is 44.5 W maximum, which factors into enclosure thermal calculations.","metaTitle":"Siemens 3VA1220-4EF32-0DH0 SENTRON MCCB, 200A 3-Pole, 121kA","metaDescription":"Siemens 3VA1220-4EF32-0DH0 SENTRON molded case circuit breaker, 200A at 40°C, 3-pole, 121 kA breaking at 240 V.
