Product details

What this breaker does in a motor branch

Rated 12.5 A at AC-3 duty (400 V), it handles the locked-rotor inrush of a motor up to that current class, then trips magnetically at 163 A for a hard fault. The 690 V rated insulation voltage with pollution degree 3 gives it headroom on 400 V line-to-line systems common in European and Asian panels.

Width 45 mm, depth 96 mm, height 97 mm. Screw terminals accept 2x (0.75 to 2.5 mm²) solid/stranded. Torque 0.8–1.2 N·m. Operating -20 to +60 °C.

Substance prohibition (RoHS) compliance date 05/01/2012. Shock resistance 25g / 11 ms per IEC 60068-2-27. Surge voltage resistance 6 kV. Relative humidity 10–95 % during operation. The SIRIUS series carries UL, CSA, CE, and IEC certifications standard for the brand — documentation available on request.

Frequently asked questions

Will 3RV6311-1KC10 drop into a panel specified around 3RV6011-0CA10?

Both are S00 frame size on 45 mm width and share the same DIN rail mounting pattern. Terminal layout and clearance requirements are identical — no rewiring needed for the footprint. The key difference is the trip curve and current rating; verify the 12.5 A setting matches your motor FLA before swapping.
