Product Positioning

The SIRIUS 3RV2021-4PA10 is a basic model of Siemens S0 frame motor protection circuit breaker with an adjustable current range of 30 to 36A and phase sequence loss sensing function, making it suitable as a main protection element for motor circuits.

Core Product Advantages and Features

Adjustable overload protection

The current adjustment range is 30 to 36A, set according to the motor's rated current, providing accurate overload protection.

CLASS 10 breakout feature

When an overload occurs, it operates according to the characteristics of CLASS 10, reacting quickly to reduce the risk of motor damage.

Phase sequence loss sensing

It has phase sequence and phase loss sensing capabilities, which can detect abnormal power conditions early and trip the protection.

Auxiliary contacts can be added.

Additional front-mounted or side-mounted auxiliary contact modules can be installed to expand control and signal feedback functions.
