Product details

Motor protection breaker with Class 10 trip and 100 kA SCCR

The Siemens SIRIUS 3RV2011-0KA20-ZX95 is a motor-protection circuit breaker with a Class 10 trip characteristic, meaning it disconnects the motor within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors from locked-rotor heating. It is rated 0.2 kW at 230 V AC (1 hp at 460/480 V, 0.5 hp at 575/600 V) and carries a 100 kA short-circuit breaking capacity across the 240–690 V range, so it safely interrupts high-fault currents without cascading upstream. The main circuit connects via spring-loaded terminals; no screw tightening needed on the power side. The unit occupies 45 mm width on the rail, with 97 mm depth and 106 mm height.

Frequently asked questions

What is the difference between 3RV2011-0KA20-ZX95 and 3RV2011-0BA20?

The 3RV2011-0BA20 is a sibling in the same SIRIUS frame, sharing the same Class 10 trip and DIN-rail footprint, but the -ZX95 variant carries a different accessory or factory-set option. Both mount identically on 35 mm DIN rail; panel rewiring is not required to swap between them if the terminal arrangement is the same, but verify the specific accessory configuration before substitution.

What is the depth of 3RV2011-0KA20-ZX95?

The depth is 97 mm.

What is the width of 3RV2011-0KA20-ZX95?

The width is 45 mm.

Will 3RV2011-0KA20-ZX95 drop into a panel specified around 3RV2011-0BA20 without rewiring?

Both share the same mounting footprint — screw and snap-on onto 35 mm DIN rail — and the same basic terminal arrangement, so physical fit is identical. No rewiring of the rail position is needed, but confirm that any accessory or factory-set option on the -ZX95 matches the -BA20's configuration before committing the BOM line.
