The interrupting capacity drops as line voltage climbs: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. Above that it starts stepping down: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. ## Auxiliary wiring and undervoltage release The UVR drops the breaker if control voltage falls — common on safety circuits or emergency-stop chains where you need the load to drop on power loss. The auxiliary contacts let a PLC or status lamp read the breaker position without climbing into the main lugs.","metaTitle":"Siemens 3VA1220-6MH32-0DH0 SENTRON MCCB, 200 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0DH0 molded case circuit breaker, 200 A, 3-pole, 220 kA at 240 V.
