| Design Of The Product | For transformer protection |
Dimensions are 45 mm wide, 97 mm deep, 106 mm tall — the 45 mm width matches the standard S00 footprint, occupying one 45 mm module on the DIN rail. Screwdriver shaft diameter 3 mm, tip size 3.0 x 0.5 mm for the terminal actuation.
Temperature compensation is active across the full operating range.
No ground fault detection on this variant — that function is handled separately upstream or by a dedicated RCD. The breaker is for transformer primary protection only.
Both are S00 frame size breakers with the same 45 mm width and snap-on DIN rail mounting, so the mechanical fit is identical. However, the 3RV2411-0EA20 is a transformer-protection design with a Class 10 trip curve, while the 3RV2011-0BA20 is a standard motor-protective breaker — verify the trip characteristic matches your load before swapping.
The depth is 97 mm, width 45 mm, height 106 mm. The 97 mm depth includes the body and terminal projection; clearance of 50 mm above and below is required for heat dissipation and wiring access.
