Rated insulation voltage is 800 V, and the interrupting ratings climb to 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. 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.
