The frame is sized for up to 250 A maximum, meaning you can swap the trip unit later if the load grows within that limit. Front connection via box terminals, IP40 on the front — standard for a panelboard or enclosed switchboard installation. No auxiliary contacts come fitted (0 CO contacts), so if you need remote status signaling, plan a separate auxiliary switch block.","metaTitle":"Siemens SENTRON 3VM1220-4EE46-0AA2 MCCB, 200 A, 121 kA at 24","metaDescription":"Siemens SENTRON 3VM1220-4EE46-0AA2 molded case circuit breaker, 200 A rated continuous current, 121 kA interrupting at 240 V.
