Integrator's spec recap
Rated 200 A continuously at 40 °C ambient, it holds that rating flat through 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 — useful when the breaker sits in a crowded enclosure with elevated internal temperatures. The interrupting ratings are 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V, giving ample SCCR headroom for most industrial service-entrance and feeder applications. An undervoltage release (UVR) is built in, so the breaker trips on loss of control voltage — a common requirement for safety disconnects on machine tools and conveyors.
Dimensions are 158 mm high, 140 mm wide, and 70 mm deep — a standard footprint for a 4-pole SENTRON 3VA frame. The breaker mounts via screw-clamp terminals and occupies a cutout sized for the 3VA family; verify the existing panel's bus-bar spacing and phase-to-phase clearance before committing the BOM. Maximum power loss is 44.5 W, which should be factored into the enclosure's thermal budget if the panel is sealed or tightly packed.
The 121 kA interrupting capacity at 240 V and 75.6 kA at 415 V mean this breaker can be used as a main or feeder device ahead of lower-rated branch breakers, provided the let-through energy is within the downstream device's withstand ratings. No communication function or ground-fault monitoring is included on this variant — it is a pure line-protection device with undervoltage release only.
