Product Positioning

The 3RV2011-4AA20 is a motor starting protection circuit breaker with an S00 housing in the Siemens SIRIUS 3RV2011 series, with a current setting range of 10–16 A (one step smaller than the S0 housing used in the 3RV2021). It belongs to the upper current limit specification of this series and is commonly used in medium and large three-phase motor circuit protection applications.

Core Product Advantages and Features

Thermo-magnetic composite tripping mechanism

It integrates thermal overload components and electromagnetic instantaneous tripping to reliably cut off the circuit when there is an abnormal current of 10–16 A, protecting the motor and the circuit.

Wide current adjustment margin

The 10–16 A current setting range can cover the rated current of various medium and large motors, making it convenient to fine-tune the protection action point on site according to the actual load.

S00 Miniaturized Housing

It uses the SIRIUS 3RV2011 series S00 enclosure, which is more compact than the 3RV2021 S0 enclosure, making it easier to plan the space in the distribution box.
