The interrupting ratings tell you where this breaker can be applied: 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 — that's a high-fault-capacity breaker for strong utility feeds or transformer secondaries. At 200 A continuous, it carries full load without derating up to 50 °C; above that, the thermal curve steps down: 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 at rated current — factor that into enclosure ventilation if you're packing multiple breakers in a confined panel.","metaTitle":"Siemens 3VA1220-6MH32-0AF0 SENTRON MCCB, 200 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0AF0 molded case circuit breaker, 200 A, 3-pole, 220 kA at 240 V interrupting rating.
