Product details

Its 1.25 A rated operational current (AC-3 at 400 V) and thermal-magnetic overload release (Class 10) mean it protects small motors — fractional-horsepower pumps, fans, or conveyors — from sustained overload and short-circuit faults. The magnetic short-circuit trip clears hard faults fast, while the thermal element allows a brief inrush before tripping, matching motor start curves.

Snap-on mounting onto 35 mm DIN rail per DIN EN 60715, with screw terminals for the main circuit (2x 0.75–2.5 mm² solid/stranded, or 2x 4 mm²).

Frequently asked questions

Where can I buy the 3RV6011-0KA10?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 3RV6011-0KA10 drop into a panel specified for 3RV6011-0CA10 without rewiring?

Both are SIRIUS size S00 breakers with the same 45 mm width, 96 mm depth, and screw-terminal arrangement. The 3RV6011-0KA10 is a 1.25 A Class 10 unit; the 3RV6011-0CA10 carries a different current rating. Panel fit is identical, but verify the current setting matches the motor full-load amps before swapping.

What compliance documentation does Siemens provide for 3RV6011-0KA10?

The part carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance. Standard Siemens documentation includes the declaration of conformity and environmental compliance sheets.
