That design designation means the thermal and magnetic trip curves are shaped to handle transformer inrush without nuisance tripping — a different profile from a standard motor-protective breaker. ## Breaking capacity — what 100 kA means here This breaker carries a 100 kA interrupting rating at 240 V, 400 V, 500 V, and 690 V AC. That is a flat 100 kA across the entire common industrial voltage range — you do not need to derate the fault-interrupt capability as line voltage rises. For a transformer primary circuit, that matters: a large transformer can feed a sustained fault current well above 50 kA, and this breaker clears it without cascading upstream. The rated operational voltage for AC-3 motor-switching duty is 690 V maximum, but the transformer-protection design is the primary role here. Dimensions: 97 mm deep, 45 mm wide, 144 mm tall. That zero forward clearance is useful in a tight enclosure; the breaker can sit flush against the back panel or a gland plate. Screw terminals with M4 bolts; Pozidriv size 2 tip, shaft diameter 5 to 6 mm. ## Environmental tolerance That -20 °C floor is fine for most indoor industrial panels; if the enclosure sits in an unheated warehouse in a cold climate, verify the ambient stays above that during operation. No ground-fault or phase-failure detection built in — this is a straight thermal-magnetic breaker, not an electronic protection relay.","metaTitle":"Siemens 3RV2811-0DD10 SIRIUS Circuit Breaker, 100 kA at 400","metaDescription":"Siemens SIRIUS 3RV2811-0DD10 circuit breaker for transformer protection. 100 kA breaking capacity at 400 V AC.
