That kind of SCCR headroom means this breaker handles high-fault-capacity distribution — think large transformer secondaries or industrial mains where upstream coordination demands a stiff interrupting rating. Above that, it derates linearly: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. If the panel runs hot — say next to a drive bank or in a non-conditioned enclosure — you need to size upstream for the derated number, not the nameplate 200 A. ## Integration notes Dimensions: 140 mm wide, 158 mm tall, 70 mm deep. Mechanical endurance is rated at 15,000 operations. The TM240 trip unit is thermal-magnetic; no phase-failure detection, no ground-fault monitoring, no communication function. If your panel needs those, you'd step up to the electronic-trip variants in the same 3VA family.","metaTitle":"Siemens 3VA1220-6EF42-0DH0 SENTRON MCCB, 200 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0DH0 molded case circuit breaker, 200 A rated, 4-pole, TM240 thermal-magnetic trip, 220 kA at 240 V.
