Above that, it derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C (–). Maximum power loss is 42 W, which matters for enclosure heat rise calculations. ## Breaking Capacity by Voltage The interrupting rating drops as system voltage climbs: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V (–). That's enough for most transformer-fed services, but verify against your available fault current. ## Auxiliaries and Releases The shunt trip lets you remotely open the breaker from a PLC or emergency-stop circuit — no undervoltage release on this variant. The trip indicator and voltage trigger are present, so you get a local mechanical flag and a remote signal when it trips. Dimensions: 105 mm wide, 158 mm high, 70 mm deep.","metaTitle":"Siemens 3VA1220-5EF32-0KH0 SENTRON MCCB, 200A, 3-Pole, 187kA","metaDescription":"Siemens 3VA1220-5EF32-0KH0 SENTRON molded case circuit breaker, 200A rated at 40°C, 3-pole, 187kA breaking at 240V.
