The interrupting ratings tell the real story: 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. That's a lot of fault-clearing headroom for a 200 A frame — the 415 V figure alone covers most industrial secondary-distribution panels without worrying about upstream coordination. The TM240 release is a fixed-thermal, fixed-magnetic design — no field-adjustable trip settings. For a line-protection role, that's fine: you size the breaker to the cable or bus, not to a variable load. ## Derating and panel fit The breaker holds 200 A flat from 40 °C to 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C.","metaTitle":"Siemens 3VA1220-6EF32-0AG0 SENTRON MCCB, 200 A, 220 kA at 24","metaDescription":"Siemens 3VA1220-6EF32-0AG0 SENTRON molded case circuit breaker, 200 A rated, 220 kA interrupting at 240 VAC. 3-pole line protection with TM240 release.
