| Design Of The Product | For motor protection |
At 690 V AC the breaking capacity drops to 4 kA, so verify your system voltage against the rating table. Rated motor power is 0.8 kW at 230 V. The auxiliary contacts handle 1 A at 24 V and 0.5 A at 230 V — enough to signal a PLC input or drop out a contactor coil.
At 45 mm wide and 97 mm deep, it takes one standard DIN module slot. The screw-type terminals on the main circuit accept 2×(0.5…1.5 mm²) solid or stranded.
This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — stock levels and lead time are confirmed at quote time.
The 3RV2021-1FA15 is a physically similar SIRIUS motor protection breaker but carries different thermal setting ranges and breaking capacities. Verify your motor full-load current and available fault current against the 3RV2021-1FA15 datasheet before substituting — the 3RV2011-1EA15-0BA0 remains the direct fit for the original BOM line.
Both mount on 35 mm DIN rail and share the same 45 mm width footprint, so mechanical fit is identical. However, the terminal layout and auxiliary contact configuration may differ — confirm wiring before swapping without a panel recheck.
