Rated for voltages from 20 to 690 V, this breaker delivers a breaking capacity of 100 kA at 240 V, 30 kA at 400 V, and 2 kA at 690 V.
Clearance requirements: 50 mm upward, 50 mm downward, 30 mm to the side, zero forward or backward. The any-position mounting lets you orient it vertically or horizontally in the enclosure. The 45 mm width matches standard 45 mm module spacing on DIN rail, so it fills one slot in a typical panel layout.
The 3RV2411-4AA20 is rated for transformer protection, not general motor or feeder duty. Its gL/gG fuse coordination limits are 80 A at 240 V, 63 A at 400 V, 50 A at 500 V, and 40 A at 690 V — these are the maximum upstream fuse sizes for selective coordination. The breaker's own breaking capacity at 400 V is 30 kA, sufficient for most industrial transformer secondaries.
